Zatrucie ołowiem
Epidemiologia
Zatrucie ołowiem stanowi istotne wyzwanie zdrowia publicznego, szczególnie w populacjach dzieci i kobiet w wieku rozrodczym, z globalnym obciążeniem przekraczającym 1,5 miliona zgonów w 2021 roku, głównie z powodu chorób układu sercowo-naczyniowego. Epidemiologiczne dane wskazują, że około 1 na 3 dzieci na świecie ma poziom ołowiu we krwi przekraczający wytyczne WHO, a w USA około 500 000 dzieci w wieku 1-5 lat ma stężenie ołowiu ≥5 µg/dL. Mimo spadku standaryzowanych wskaźników śmiertelności o 20,66% i DALY o 29,23% w latach 1990-2019, bezwzględna liczba zgonów i lat życia skorygowanych niepełnosprawnością wzrosła odpowiednio o 70,19% i 35,26%, co wiąże się ze starzeniem się i wzrostem populacji. Dzieci poniżej 3 roku życia są szczególnie narażone na zatrucie, absorbując nawet 45-krotnie więcej ołowiu niż dorośli, a ekspozycja jest silnie skorelowana z niższym statusem społeczno-ekonomicznym. Wartości referencyjne dla interwencji zostały obniżone do 3,5 µg/dL (CDC, USA) i 5 µg/dL (UKHSA, Wielka Brytania), podkreślając brak bezpiecznego poziomu ołowiu w organizmie.

Epidemiologia zatrucia ołowiem
Zatrucie ołowiem pozostaje jednym z najważniejszych problemów zdrowia środowiskowego na świecie, stanowiąc znaczące zagrożenie dla zdrowia publicznego, szczególnie dla dzieci i kobiet w wieku rozrodczym. Według danych Światowej Organizacji Zdrowia (WHO), ekspozycja na ołów przyczyniła się do ponad 1,5 miliona zgonów na świecie w 2021 roku, głównie z powodu działania na układ sercowo-naczyniowy.1 Mimo że zatrucie ołowiem jest całkowicie możliwe do zapobiegania, nadal stanowi powszechne zagrożenie dla zdrowia, zwłaszcza w krajach rozwijających się.
Skala problemu na świecie
Według danych epidemiologicznych, około jedno na 38 dzieci w Stanach Zjednoczonych doświadcza zatrucia ołowiem, a szacuje się, że około pół miliona dzieci w wieku 1-5 lat ma poziom ołowiu we krwi powyżej 5 mikrogramów na decylitr (µg/dL).2 Światowa skala problemu jest jeszcze większa – WHO informuje, że 1 na 3 dzieci na świecie ma podwyższony poziom ołowiu we krwi, przekraczający wytyczne zdrowotne WHO.3
W badaniu globalnego obciążenia chorobami związanymi z ekspozycją na ołów w latach 1990-2019 wykazano, że chociaż standaryzowane względem wieku wskaźniki śmiertelności i obciążenia chorobami zmniejszyły się odpowiednio o 20,66% i 29,23%, to bezwzględna liczba zgonów i lat życia skorygowanych niepełnosprawnością (DALY) wzrosła o 70,19% i 35,26% w kontekście starzenia się populacji i jej wzrostu.4 Najwyższe wartości frakcji przypisanej populacji (PAF) odnotowano głównie w Azji Południowej, Azji Wschodniej, na Bliskim Wschodzie i w Afryce Północnej.5
Czynniki ryzyka i epidemiologia w grupach wrażliwych
Dzieci są szczególnie narażone na zatrucie ołowiem, mogąc wchłaniać nawet 45 razy więcej ołowiu niż dorośli z przyjętej dawki.6 Najwyższe ryzyko występuje u dzieci poniżej 3 roku życia, głównie ze względu na częstsze zachowania typu „ręka-usta” oraz lepsze wchłanianie żołądkowo-jelitowe ołowiu.78
Dane demograficzne wskazują na nierówności w narażeniu na ołów. W Stanach Zjednoczonych i Wielkiej Brytanii wyższy odsetek przypadków zatrucia ołowiem występuje u dzieci mieszkających w obszarach o niższym statusie społeczno-ekonomicznym. W raporcie z brytyjskiego systemu nadzoru nad ekspozycją na ołów u dzieci (LEICSS) z 2023 roku, 72% przypadków pochodziło z dwóch najbardziej zubożałych kwintyli według wskaźnika deprywacji wieloczynnikowej (IMD), a ponad 50% przypadków zamieszkiwało obszary o najwyższym poziomie deprywacji.9 Podobne dane raportowano w 2024 roku, gdzie 66% przypadków pochodziło z dwóch najbardziej zubożałych kwintyli IMD.10
Chociaż brak jest dowodów na biologiczne predyspozycje rasowe do toksyczności ołowiu, współistniejące czynniki, takie jak niedożywienie i niższy status społeczno-ekonomiczny, są wyraźnie związane z przewlekłym zatruciem ołowiem.11 Zatrucie ołowiem zwykle wpływa w równym stopniu na mężczyzn i kobiety, chociaż u dorosłych mężczyźni mogą mieć wyższe poziomy ołowiu ze względu na narażenie zawodowe.12 Dane z systemów nadzoru wskazują jednak, że wśród dzieci z zatruciem ołowiem przeważają chłopcy – np. w Wielkiej Brytanii stanowili oni 68% przypadków w 2022 roku i 65% w 2023 roku.1314
Trendy epidemiologiczne i postępy w ograniczaniu ekspozycji
Na przestrzeni ostatnich dekad w wielu krajach rozwiniętych obserwuje się stopniowy spadek poziomów ołowiu we krwi. W Stanach Zjednoczonych wycofanie benzyny ołowiowej między 1976 a 1995 rokiem wiązało się z ponad 90% redukcją średniego stężenia ołowiu we krwi.15 Według danych z systemu nadzoru ABLES, w ciągu ostatnich 18 lat udokumentowano 54% spadek krajowych wskaźników rozpowszechnienia poziomów ołowiu we krwi ≥25 µg/dL.16
W Wisconsin odsetek dzieci z poziomem ołowiu we krwi równym lub wyższym niż 5 µg/dL zmniejszył się z 6,2% w 2012 roku do 3,2% w 2023 roku.17 Podobne trendy spadkowe obserwuje się w innych stanach USA i krajach rozwiniętych, chociaż warto zaznaczyć, że obniżenie wartości referencyjnej ołowiu we krwi przez CDC z 5 µg/dL do 3,5 µg/dL spowodowało dwukrotny wzrost liczby dzieci klasyfikowanych jako zatrucie ołowiem – w Wisconsin 6,3% testowanych dzieci miało poziom ołowiu we krwi równy lub większy niż 3,5 µg/dL w 2023 roku.18
Systemy nadzoru nad zatruciem ołowiem
Nadzór nad zatruciem ołowiem jest kluczowym elementem strategii zdrowia publicznego w zakresie identyfikacji, monitorowania i eliminacji tego problemu. W 1995 roku raportowanie poziomów ołowiu we krwi stało się pierwszym stanem nieinfekacyjnym podlegającym obowiązkowi zgłaszania na poziomie krajowym w USA.19 Systemy nadzoru są niezbędne do identyfikacji pozostałych obszarów ryzyka, śledzenia trendów czasowych i oceny skuteczności interwencji.
Krajowe systemy nadzoru
W Stanach Zjednoczonych Centra Kontroli i Prewencji Chorób (CDC) współpracują z Radą Epidemiologów Państwowych i Terytorialnych (CSTE) w celu rozwijania krajowego systemu nadzoru monitorującego poziomy ołowiu we krwi.20 Głównym źródłem danych nadzoru nad ołowiem na poziomie stanowym lub lokalnym są zwykle stanowe Programy Zapobiegania Zatruciom Ołowiem u Dzieci (CLPPP) i/lub stanowe Programy Nadzoru Epidemiologicznego nad Ołowiem we Krwi Dorosłych (ABLES).21
CDC wspiera rozwój Systemu Nadzoru nad Zdrowymi Domami i Zatruciem Ołowiem (HHLPSS) jako platformy zarządzania danymi do nadzoru nad ołowiem we krwi.22 Dane nadzoru nad ołowiem we krwi są cennym zasobem do zarządzania programami i identyfikacji obszarów geograficznych pozostających w grupie ryzyka.23
W Wielkiej Brytanii funkcjonuje System Nadzoru nad Ekspozycją na Ołów u Dzieci (LEICSS), koordynowany przez Brytyjską Agencję Bezpieczeństwa Zdrowotnego (UKHSA). System ten powiadamia Zespoły Ochrony Zdrowia (HPT) o przypadkach podwyższonego stężenia ołowiu we krwi u dzieci w wieku 0-15 lat w Anglii, co inicjuje zarządzanie przypadkami i interwencje zdrowia publicznego mające na celu usunięcie źródeł ekspozycji.24
Zmiany wartości referencyjnych i progowych
Na przestrzeni lat wartości progowe dla interwencji w przypadku zatrucia ołowiem ulegały zmianom, odzwierciedlając rosnącą świadomość szkodliwości nawet niskich poziomów ołowiu. Aktualnie nie istnieje bezpieczny poziom ołowiu w organizmie, a ekspozycja nawet na niewielkie ilości może prowadzić do obniżenia IQ i problemów behawioralnych.2526
CDC w roku 2021 obniżyło wartość referencyjną ołowiu we krwi z 5 µg/dL do 3,5 µg/dL dla dzieci w wieku 1-5 lat.27 Wartość ta opiera się na 97,5 percentylu rozkładu poziomów ołowiu we krwi u dzieci w USA w wieku 1-5 lat.28 Wiele stanów i krajów dostosowało swoje wytyczne do tej nowej wartości referencyjnej.
W Wielkiej Brytanii, po przeglądzie dowodów dotyczących szkodliwości ekspozycji na ołów u dzieci, UKHSA zaleciła obniżenie progu interwencji zdrowia publicznego dla Anglii z 10 µg/dL (0,48 µmol/L) do 5 µg/dL (0,24 µmol/L) od 5 lipca 2021 roku.29 Jak oczekiwano, doprowadziło to do gwałtownego wzrostu liczby zgłaszanych przypadków.
Nadzór nad zatruciem ołowiem u dorosłych
Program Nadzoru Epidemiologicznego i Monitorowania Ołowiu we Krwi Dorosłych (ABLES) jest systemem nadzoru koordynowanym przez Narodowy Instytut Bezpieczeństwa i Zdrowia Zawodowego (NIOSH), odział CDC. W wielu stanach USA, jak np. Oklahoma, program ten rozpoczął działalność w 1995 roku.30
Misją programu ABLES jest realizacja celu Healthy People 2020 dotyczącego Bezpieczeństwa i Zdrowia Zawodowego (OSH-7), który zakłada 10% redukcję liczby osób z podwyższonym stężeniem ołowiu we krwi w wyniku narażenia zawodowego.31 Program ABLES ma na celu:
- Utrzymywanie systemu nadzoru nad ołowiem we krwi dorosłych oraz gromadzenie i analizę danych w celu identyfikacji częstości występowania i rozpowszechnienia podwyższonych poziomów ołowiu we krwi w populacji dorosłych (w wieku 16 lat lub starszych)32
- Dostarczanie rocznych danych do NIOSH, które są uwzględniane w artykułach Morbidity and Mortality Weekly Report (MMWR) dotyczących poziomów ołowiu we krwi dorosłych w skali krajowej33
- Pomoc NIOSH w identyfikacji niebezpiecznych branż i zawodów w celu wdrożenia strategii profilaktyki pierwotnej dla eliminacji zatrucia ołowiem u dorosłych i powiązanego zatrucia u dzieci34
W 2007 roku w Stanach Zjednoczonych ponad 9800 dorosłych zgłoszono przez 38 stanów jako osoby z podwyższonym poziomem ołowiu we krwi równym lub większym niż 25 µg/dL. 95% tych dorosłych, u których zidentyfikowano źródło ekspozycji na ołów, było narażonych w miejscu pracy.35 Dla porównania, średni poziom ołowiu we krwi dla ogółu populacji w USA wynosi 2 µg/dL.36
Regionalne różnice w nadzorze i wykrywalności
Istnieją znaczące różnice regionalne w systemach nadzoru i wykrywalności zatrucia ołowiem. W Anglii w 2023 roku wskaźnik wykrywalności przypadków na milion dla dzieci w wieku 0-15 lat wynosił 21 przypadków na milion, ale występowały duże różnice regionalne. Najwyższe wskaźniki zgłoszeń odnotowano w regionie Yorkshire i Humber (75 na milion), a najniższe w regionie East of England (8 na milion).37
Podobnie w USA występują znaczące różnice między stanami i regionami. Według statystyk z międzynarodowych badań populacyjnych, liczba przypadków zgłaszanych do systemów nadzoru jest znacznie niższa niż szacowana częstość występowania ekspozycji na ołów.3839 W Nowym Meksyku, mimo wzrostu rocznych wskaźników badań przesiewowych, tylko około 10% dzieci w wieku 1-5 lat zostało przebadanych pod kątem ekspozycji na ołów w 2010 roku.40
Rola systemów nadzoru w profilaktyce zatrucia ołowiem
Systemy nadzoru nad zatruciem ołowiem pełnią kluczową rolę w strategiach zdrowia publicznego, umożliwiając terminowe działania zarówno na poziomie indywidualnym, jak i populacyjnym. Dane gromadzone przez te systemy służą do kierowania interwencjami, identyfikacji trendów i oceny skuteczności programów profilaktycznych.
Wykorzystanie danych nadzoru do interwencji zdrowotnych
Dane z nadzoru nad zatruciem ołowiem są wykorzystywane do identyfikacji przypadków wymagających interwencji medycznej i środowiskowej. Systemy nadzoru ułatwiają terminowe działania w przypadku indywidualnych przypadków, co jest kluczowe, ponieważ głównym sposobem leczenia przypadków ekspozycji na ołów jest szybkie usunięcie domniemanego źródła narażenia.41
W wielu stanach USA i krajach na świecie dane nadzoru są wykorzystywane do:
- Zapewnienia, że dzieci potencjalnie narażone na działanie ołowiu otrzymują odpowiednią opiekę42
- Identyfikacji i remediacji źródeł ekspozycji na ołów43
- Kierowania wysiłków związanych z badaniami przesiewowymi, działaniami informacyjnymi i zasobami edukacyjnymi44
- Monitorowania postępów w kierunku obniżenia poziomów ołowiu we krwi45
Departament Zdrowia Nowego Jorku otrzymuje corocznie wyniki badań poziomu ołowiu we krwi dla ponad 300 000 dzieci poniżej 6 roku życia i zapewnia szereg usług dla dzieci w zależności od poziomu ołowiu we krwi, wieku i ryzyka ekspozycji.46 Podobnie, Teksaski Program Zapobiegania Zatruciom Ołowiem u Dzieci (TXCLPPP) nadzoruje monitoring wyników badań ołowiu we krwi u dzieci w wieku poniżej 15 lat i wykorzystuje te dane do opracowywania i oceny bieżących wysiłków na rzecz zapobiegania zatruciom ołowiem w całym stanie.47
Wdrażanie nowych technologii w systemach nadzoru
Nowoczesne systemy nadzoru nad zatruciem ołowiem wykorzystują zaawansowane technologie do poprawy efektywności gromadzenia i analizy danych. W Michigan organizacja Altarum prowadzi wysiłki na rzecz poprawy wydajności i dokładności danych, które trafiają do Michigan Childhood Lead Poisoning Surveillance System, współpracując z Departamentem Zdrowia i Usług Społecznych Michigan (MDHHS), dostawcami usług medycznych i dostawcami elektronicznej dokumentacji medycznej (EHR).48
W Wielkiej Brytanii, postęp w rozwoju nadzoru nad przypadkami zatrucia ołowiem kontynuowano w 2023 roku, wdrażając nowe narzędzia, takie jak kwestionariusz ekspozycji środowiskowej (ESQ), który pomaga w identyfikacji potencjalnych źródeł ołowiu w zarządzaniu przypadkami. Ponadto, Environmental Public Health Surveillance System (EPHSS) gromadzi i integruje dane z wybranych baz danych dotyczących zagrożeń środowiskowych, ekspozycji i danych dotyczących wyników zdrowotnych.49
Międzynarodowe inicjatywy nadzoru
Zatrucie ołowiem jest problemem globalnym, wymagającym współpracy międzynarodowej. Organizacja Pure Earth współpracuje z rządami w celu wzmocnienia nadzoru zdrowotnego. Od 2018 roku Pure Earth współpracowała z dziewięcioma krajami (Bangladesz, Kolumbia, Ghana, Indie, Indonezja, Kirgistan, Meksyk, Peru i Filipiny) w celu wdrożenia badań poziomu ołowiu we krwi na dużą skalę.5051
Te pionierskie oceny, często przeprowadzane po raz pierwszy w dotkniętych krajach, dostarczają podstaw dla krajowych planów działania i stanowią bazę do śledzenia postępów i identyfikacji potencjalnych nowych źródeł ekspozycji na ołów.52 W Meksyku Narodowy Serwis Zdrowia uwzględnił badania poziomu ołowiu we krwi w swoim krajowym badaniu zdrowotnym po raz drugi, zapewniając ciągłość nadzoru.53
W Peru organizacja Vital Strategies współpracowała z Ministerstwem Zdrowia Peru i jego Krajowym Centrum Kontroli i Zapobiegania Chorobom w celu zaprojektowania i uruchomienia pierwszego krajowego nadzoru, który testował poziom ołowiu we krwi u ponad 1000 dzieci.54 Wysiłki związane z nadzorem są rozszerzane na Kolumbię, Indonezję i inne stany indyjskie (np. Tamil Nadu i Maharashtra).55
Wyzwania i przyszłość nadzoru nad zatruciem ołowiem
Mimo postępów w nadzorze nad zatruciem ołowiem, wciąż istnieją znaczące wyzwania, które wymagają dalszych działań. Identyfikacja nowych źródeł ekspozycji, doskonalenie metod nadzoru i zwiększanie dostępności badań przesiewowych to kluczowe obszary wymagające uwagi.
Nowe źródła ekspozycji i wyzwania nadzoru
Chociaż tradycyjnie głównym źródłem ekspozycji na ołów dla dzieci w USA były farby zawierające ołów i zanieczyszczony kurz domowy56, badanie przeprowadzone w czterech jurysdykcjach w Kalifornii, Oregonie, Nowym Jorku i hrabstwie King w stanie Waszyngton wykazało, że produkty konsumenckie (np. przyprawy, kosmetyki, metalowe naczynia kuchenne i ceramika) były źródłem ekspozycji na ołów w 15-38% przypadków zatrucia ołowiem.57
Implikacje wyników tego badania wykraczają daleko poza Stany Zjednoczone. Odkrywając globalne pochodzenie tych skażonych produktów, badacze podkreślają pilną potrzebę międzynarodowej współpracy w rozwiązywaniu kryzysu zatrucia ołowiem.58 Autorzy podkreślają trudność w przypisaniu pojedynczego źródła ekspozycji na ołów do podwyższonych poziomów ołowiu we krwi, dodając, że dzieci mogą być narażone na kombinację źródeł ołowiu, w tym źródeł związanych z mieszkaniem i zanieczyszczonych produktów konsumenckich.59
W Anglii, dowody z systemu LEICSS wykazały, że drogi ekspozycji na ołów obejmują spożywanie wody, gleby lub kurzu zanieczyszczonego ołowiem, a także preparaty ziołowe, zanieczyszczoną żywność i przyprawy oraz używanie produktów konsumenckich, które nie spełniają standardów regulacyjnych.60
Poprawa nadzoru i badań przesiewowych
Istnieje potrzeba poprawy systemów nadzoru i zwiększenia zakresu badań przesiewowych, zwłaszcza w populacjach o wysokim ryzyku. Mimo federalnego wymogu w USA, że dzieci kwalifikujące się do Medicaid powinny być badane pod kątem ekspozycji na ołów, badania te nie zawsze są przeprowadzane.61 W Nowym Meksyku, mimo wzrostu rocznych wskaźników badań przesiewowych, tylko około 10% dzieci w wieku 1-5 lat zostało przebadanych pod kątem ekspozycji na ołów w 2010 roku.62
Badacze wzywają do utworzenia krajowej bazy danych śledzenia w celu identyfikacji produktów zawierających ołów, które są związane z podwyższonymi poziomami ołowiu we krwi w USA, co może informować o interwencjach w krajach, w których ma miejsce zanieczyszczenie.63 Taka baza danych nadzoru nad produktami konsumenckimi zbieranymi przez różne jurysdykcje podczas dochodzeń w sprawie zatrucia ołowiem pomogłaby zidentyfikować szerszy zakres produktów konsumenckich zawierających ołów, które mają wpływ na wrażliwe społeczności w USA.64
Przyszłość nadzoru nad zatruciem ołowiem
Przyszłość nadzoru nad zatruciem ołowiem obejmuje dalsze doskonalenie metod, rozszerzanie współpracy międzynarodowej i integrację z innymi systemami zdrowia publicznego. W USA, EPA kontynuuje rozwój analizy danych i nauki mapowania dla ołowiu, aby stany i społeczności miały informacje potrzebne do ukierunkowania i priorytetyzacji działań mających na celu zmniejszenie, zapobieganie i łagodzenie ryzyka ekspozycji na ołów, szczególnie dla dzieci.65
Agencja niedawno ogłosiła dostępność projektu zewnętrznego przeglądu Zintegrowanej Oceny Naukowej Ołowiu (ISA) z 2023 roku. Określa on kluczowe wnioski istotne dla polityki, w tym dotyczące populacji o zwiększonym ryzyku skutków związanych z ołowiem, stężeń ekspozycji na ołów, przy których takie skutki występują, oraz ogólnej siły dowodów potwierdzających związki między ekspozycją na ołów a skutkami zdrowotnymi lub środowiskowymi.66
Na poziomie globalnym, silne dowody epidemiologiczne, takie jak kompleksowa ocena ilościowa obciążenia chorobami przypisywanymi ekspozycji na ołów, pomogłyby w opracowaniu skutecznych strategii profilaktycznych, które zmniejszają zagrożenia związane z ekspozycją na ołów.67 Obciążenie chorobami spowodowanymi ekspozycją na ołów jest negatywnie skorelowane z Indeksem Rozwoju Społeczno-Demograficznego (SDI), dlatego odpowiednie strategie kontroli ołowiu w krajach o niskim SDI powinny być stale doskonalone poprzez takie środki, jak wzmacnianie monitorowania ołowiu we krwi w narażonych populacjach i zwiększanie świadomości na temat toksyczności ołowiu.68

Podsumowanie epidemiologii i nadzoru zatrucia ołowiem
Zatrucie ołowiem pozostaje znaczącym problemem zdrowia publicznego na całym świecie, szczególnie dla dzieci i w krajach o niskim i średnim dochodzie. Chociaż w wielu krajach rozwiniętych poczyniono znaczące postępy w zmniejszaniu ekspozycji na ołów, szacuje się, że około 1 na 3 dzieci na świecie ma podwyższone poziomy ołowiu we krwi.69
Systemy nadzoru odgrywają kluczową rolę w identyfikacji i zarządzaniu przypadkami zatrucia ołowiem, a także w informowaniu o politykach i interwencjach zdrowia publicznego. Wraz z rozwojem wiedzy naukowej na temat szkodliwości ekspozycji na ołów, wiele krajów obniżyło wartości referencyjne dla interwencji, uznając, że nie istnieje bezpieczny poziom ołowiu, szczególnie dla rozwijających się dzieci.
Przyszłe wysiłki powinny koncentrować się na zwiększaniu dostępności badań przesiewowych, poprawie nadzoru, szczególnie w krajach o niskim i średnim dochodzie, oraz na wzmocnieniu międzynarodowej współpracy w celu identyfikacji i eliminacji źródeł ekspozycji na ołów. Tylko poprzez kompleksowe podejście do zapobiegania i nadzoru możemy osiągnąć cel, jakim jest eliminacja zatrucia ołowiem jako problemu zdrowia publicznego.

Exposure to lead can affect multiple body systems and is particularly harmful to young children and women of child-bearing age. […] Lead exposure was attributed to more than 1.5 million deaths globally in 2021, primarily due to cardiovascular effects. […] Young children are particularly vulnerable to lead poisoning as they may absorb up to 45 times as much lead as adults from an ingested dose. […] Exposure to lead-contaminated soil and dust resulting from battery recycling and mining has caused outbreaks of mass lead poisoning, including deaths in young children, in some countries. […] Lead exposure can have serious consequences for the health of children. […] Lead exposure causes a significant burden of disease. The Institute for Health Metrics and Evaluation (IHME) estimates that more than 1.5 million deaths globally were attributed to lead exposure in 2021, primarily due to cardiovascular effects. […] WHO identifies lead as one of 10 chemicals of major public health concern requiring action by Member States to protect the health of workers, children and women of reproductive age.
- #2 Lead poisoning epidemiology and demographics – wikidochttps://www.wikidoc.org/index.php/Lead_poisoning_epidemiology_and_demographics
Lead poisoning epidemiology and demographics On the Web […] The incidence of lead poisoning is approximately one in 38 U.S. children in the United States. […] The prevalence of lead poisoning in children, according to the CDC, in the United States is estimated to be approximately half million children ages 1-5 with blood lead levels above 5 micrograms per deciliter (g/dL). […] The case-fatality rate of lead poisoning is approximately 400,000 U.S. deaths per year. […] The incidence of lead poisoning is higher in children; the median age at diagnosis is 1-5 years. […] Lead-contaminated household dust is the major source of lead exposure to children in the U.S. […] Although children are at greater risk from lead exposure, adult exposures can also result in harmful health effects. […] There is no racial predilection to lead poisoning.
- #3 Childhood Lead Poisoning Prevention – Vital Strategieshttps://www.vitalstrategies.org/programs/childhood-lead-poisoning-prevention/
Despite clear evidence of harm, many countries do not monitor lead exposure, and only 43% of countries have limits on lead in paint that are legally binding. […] 1 in 3 of the world’s children have elevated blood levels at or above WHO health-based guidelines. […] Vital has supported governments and organizations to initiate surveillance systems that help characterize the lead poisoning problem and inform policy actions, bringing strong expertise in environmental health surveillance to well-established government and technical partnerships. […] In Peru, Vital partnered with the Ministry of Health of Peru and its National Center for Disease Control and Prevention to design and launch the first national surveillance, which tested blood lead levels in over 1,000 children. […] Surveillance efforts are being expanded to Colombia, Indonesia, and other Indian states (e.g., Tamil Nadu and Maharashtra).

Understanding the spatio-temporal patterns of the global burden of various diseases resulting from lead exposure is critical for controlling lead pollution and disease prevention. […] From 1990 to 2019, the number of deaths and DALYs resulting from lead exposure increased by 70.19% and 35.26%, respectively; however, the ASMR and ASDR decreased by 20.66% and 29.23%, respectively. […] High PAFs occurred mainly in South Asia, East Asia, the Middle East, and North Africa. […] Our findings showed that the global impact of lead exposure and its burden increased from 1990 to 2019 and varied significantly according to age, sex, region, and resulting disease. Effective public health measures and policies should be adopted to prevent and control lead exposure. […] Strong epidemiological evidence, such as a comprehensive quantitative assessment of the disease burden attributable to lead exposure, would aid the development of effective prevention strategies that reduce the hazards of lead exposure.

The Institute for Health Metrics and Evaluation (IHME) estimates that more than 1.5 million deaths globally were attributed to lead exposure in 2021, primarily due to cardiovascular effects. […] WHO identifies lead as one of 10 chemicals of major public health concern requiring action by Member States to protect the health of workers, children and women of reproductive age.
- #7 Lead Toxicity: Background, Pathophysiology, Etiologyhttps://emedicine.medscape.com/article/1009587-overview
Children are more likely than adults to have elevated blood lead levels (BLLs). More hand-to-mouth behavior and better gastrointestinal absorption of lead are some factors contributing to higher BLLs in children. In fact, lead poisoning is said to be the most common environmental illness of children in the United States. The incidence varies with age, socioeconomic status, the population of a given community, race, and the age of the home. […] Adult Blood Lead Epidemiology and Surveillance (ABLES) is a program that works with states to accurately measure trends in work-related adult BLLs, to better target interventions and prevent lead exposures. The National Institute for Occupational Safety and Health (NIOSH) in 2015 designated 5 g/dl of whole blood, in a venous blood sample, as the reference BLL for adults. A BLL 5 g/dL is considered abnormal.

Children younger than 3 years are at the greatest risk for lead poisoning. […] Adults are now believed to be affected at a lower level of exposure than was once assumed. […] Because of occupational exposures, men have higher lead levels than women. No sex difference in incidence is reported in children. […] Although no compelling evidence exists that any particular race is biologically predisposed to lead toxicity, covariant conditions such as poor nutrition and lower socioeconomic status clearly are associated with chronic lead poisoning. […] Overall, black non-Hispanic children appear to have the greatest risk of developing lead poisoning.

LEICSS is a national surveillance system coordinated by the UK Health Security Agency (UKHSA). The surveillance system notifies the Health Protection Teams (HPTs) of incident cases of elevated blood lead concentration in children aged 0 to 15 years in England. Notification initiates health protection case management and public health interventions to remove exposure sources. […] Following a review of the evidence of the harm of lead exposure in children, a UKHSA task and finish group recommended the lowering of the blood lead public health intervention concentration for England. Since 5 July 2021, the case definition for surveillance changed to half the original concentration, from 0.48 mol/L (equivalent to 10g/dL) to 0.24mol/L (equivalent to 5g/dL). As expected, this led to a steep increase in the number of cases being reported to LEICSS.

The CDC Blood Lead Reference Value based on the 97.5th percentile of blood lead level distribution in US children aged 1-5 years, is 3.5 g/dL. A child is considered to have an elevated blood lead level (EBLL) at a concentration of 3.5 g/dL or greater. […] Despite increases in New Mexicos annual screening rates, only about 10% of children aged 1-5 years were tested for lead exposure in 2010. […] The rates of elevated blood lead levels among children aged 1-5 years have remained at relatively stable levels during the past few years. […] Fortunately, rates of elevated blood lead levels in New Mexican children are lower relative to US rates. […] Despite the federal requirement that Medicaid-eligible children are to be tested for lead exposure, this testing does not always occur. […] From 2006 to 2010, 10,119 New Mexican residents aged 16 and older reported blood lead levels to the NMDOH. Of these, 31 adults had elevated blood lead levels (25 g/dL, 8 of which reported blood lead levels at 40 g/dL or greater). Of the adults with elevated blood lead levels, 19 were due to occupational exposures.
