RESUMEN
CONTEXT: Wisconsin-specific data revealed that not all Medicaid providers were testing children appropriately for blood lead levels and not all blood lead tests were reported to the Department of Health Services, Childhood Lead Poisoning Prevention Program. The Medicaid program requires blood lead screening for all Medicaid-enrolled children at specific ages. Wisconsin state law requires reporting of all blood lead test results. Projects were implemented to encourage appropriate testing for Medicaid-enrolled children and improve blood lead surveillance. METHODS: Medicaid billing data were linked to blood lead data to identify Medicaid-enrolled children who had not received the required tests. Medicaid provider report cards were distributed annually from 2006 to 2011 to inform providers of their compliance with federal testing requirements and of the names of children within their practice who had not been tested. Blood lead tests billed to Medicaid but not in the blood lead database were identified and billing providers were contacted to obtain the test report. RESULTS: The number of children tested increased from 81 834 children per year in 2006 to 106 003 children per year in 2010. Testing of Medicaid-enrolled children increased by 31% from 2006 to 2010. The percentage of Medicaid-enrolled children receiving an age-appropriate test increased from 46% in 2004 to a high of 55% in 2010. There were 9035 blood lead tests identified in the Medicaid billing data that had not been reported from 2007 to 2015. There were 468 billing providers who had unreported tests. All sites with unreported tests were contacted, 84% of test results were obtained, and 14% of test records could not be retrieved. Outpatient clinics accounted for the majority of all unreported tests (72%) and irretrievable test records (74%). DISCUSSION: Childhood lead poisoning prevention programs can effectively utilize Medicaid data to increase testing and improve blood lead surveillance. Primary health care providers should ensure that Medicaid-enrolled children in their care receive the age-appropriate tests. Many Wisconsin health care providers lack awareness of blood lead test reporting requirements. Outpatient clinics account for the largest proportion of unreported tests and highest priority should be given working with these sites to improve reporting practices.

BACKGROUND: Perfluoroalkyl substances (PFAS) are an emerging class of contaminants. Certain PFAS are regulated or voluntarily limited due to concern about environmental persistence and adverse health effects, including thyroid disease and dyslipidemia. The major source of PFAS exposure in the general population is thought to be consumption of seafood. OBJECTIVES: In this analysis we examine PFAS levels and their determinants, as well as associations between PFAS levels and self-reported fish and shellfish consumption, using a representative sample of the U.S. METHODS: Data on PFAS levels and self-reported fish consumption over the past 30 days were collected from the 2007-2008, 2009-2010, 2011-2012, and 2013-2014 cycles of the National Health and Nutrition Examination Survey. Twelve different PFAS were measured in serum samples from participants. Ordinary least squares regression models were used to identify factors (demographic characteristics and fish consumption habits) associated with serum PFAS concentrations. Additional models were further adjusted for other potential exposures including military service and consumption of ready-to-eat and fast foods. RESULTS: Seven PFAS were detected in at least 30% of participants and were examined in subsequent analyses (PFDA, PFOA, PFOS, PFHxS, MPAH, PFNA, PFUA). The PFAS with the highest concentrations were PFOS, followed by PFOA, PFHxS and PFNA (medians of 8.3, 2.7, 1.5 and 1.0ng/mL). Fish consumption was generally low, with a median of 1.2 fish meals and 0.14 shellfish meals, reported over the past 30 days. After adjusting for demographic characteristics, total fish consumption was associated with reduced MPAH, and with elevated PFDE, PFNA and PFuDA. Shellfish consumption was associated with elevations of all PFAS examined except MPAH. Certain specific fish and shellfish types were also associated with specific PFAS. Adjustment for additional exposure variables resulted in little to no change in effect estimates for seafood variables. CONCLUSIONS: PFAS are emerging contaminants with widespread exposure, persistence, and potential for adverse health effects. In the general population, fish and shellfish consumption are associated with PFAS levels, which may indicate an avenue for education and outreach.

Although awareness of Wisconsin's fish consumption guidelines is high among older male anglers, little is known about comprehension of guideline content, and many anglers have levels of contaminants high enough to be associated with adverse health outcomes. The Environmental Protection Agency Great Lakes Restoration Initiative supported evaluation and revision of Wisconsin's fish consumption guideline program, using a web based survey of male Wisconsin anglers over the age of 50. A total of 3740 men completed the online survey; the median age of respondents was 62 years, and nearly all had lived and fished in Wisconsin for over 10 years. Comprehension of guideline content was relatively high, although two knowledge gaps were identified, one relating to mercury exposures and fish preparation, and the other to polychlorinated biphenyl content of certain fish species. The fishing regulations booklet distributed with annual fishing licenses and warning signs posted at fishing locations were commonly reported sources of guideline information in Wisconsin. Residents of coastal counties and consumers of Great Lakes fish were more likely to report guideline knowledge and behavior changes reflective of guideline knowledge, when compared to inland residents and those not consuming Great Lakes fish, respectively. In general, Wisconsin's consumption guidelines do not appear to discourage men from eating the fish they catch; rather, the most common behavioral changes included modifying the species eaten or the water body source of their meals. Continued efforts to educate anglers about the risks and benefits of fish consumption are needed.

Fish is an important source of nutrients including omega-3 fatty acids, which may reduce risk of adverse health outcomes such as cardiovascular disease; however, fish may also contain significant amounts of environmental pollutants. The Wisconsin Departments of Health Services and Natural Resources developed a survey instrument, along with a strategy to collect human biological samples to assess the risks and benefits associated with long-term fish consumption among older male anglers in Wisconsin. The target population was men aged 50 years and older, who fish Wisconsin waters and live in the state of Wisconsin. Participants provided blood and hair samples and completed a detailed (paper) questionnaire, which included questions on basic demographics, health status, location of catch and species of fish caught/eaten, consumption of locally caught and commercially purchased fish, and awareness and source of information for local and statewide consumption guidelines. Biological samples were used to assess levels of docosahexaenoic acid (DHA), docosapentaenoic acid (DPA), eicosapentaenoic acid (EPA); vitamin D; and selenium in blood. Quantile regression analysis was used to investigate the associations between biomarker levels and self-reported consumption of fish from the Great Lakes and other areas of concern, other locally caught fish, and commercially purchased fish (meals per year). Respondents were largely non-Hispanic white men in their 60's with at least some college education, and about half were retired. Fish consumption was high (median of 54.5 meals per year), with most fish meals coming from locally-caught fish. Multivariate regression models showed that the effect of supplement use was much greater than that of fish consumption, on nutrient levels, although consumption of fish from the Great Lakes and areas of concern was significantly associated with higher levels of vitamin D even after controlling for supplement usage.

OBJECTIVES: We described disparities in infectious disease (ID) hospitalizations for American Indian/Alaska Native (AI/AN) people. METHODS: We analyzed hospitalizations with an ID listed as the first discharge diagnosis in 1998-2006 for AI/AN people from the Indian Health Service National Patient Information Reporting System and compared them with records for the general U.S. population from the Nationwide Inpatient Survey. RESULTS: The ID hospitalization rate for AI/AN people declined during the study period. The 2004-2006 mean annual age-adjusted ID hospitalization rate for AI/AN people (1,708 per 100,000 populiation) was slightly higher than that for the U.S. population (1,610 per 100,000 population). The rate for AI/AN people was highest in the Southwest (2,314 per 100,000 population), Alaska (2,063 per 100,000 population), and Northern Plains West (1,957 per 100,000 population) regions, and among infants (9,315 per 100,000 population). ID hospitalizations accounted for approximately 22% of all AI/AN hospitalizations. Lower-respiratory-tract infections accounted for the largest proportion of ID hospitalizations among AI/AN people (35%) followed by skin and soft tissue infections (19%), and infections of the kidney, urinary tract, and bladder (11%). CONCLUSIONS: Although the ID hospitalization rate for AI/AN people has declined, it remains higher than that for the U.S. general population, and is highest in the Southwest, Northern Plains West, and Alaska regions. Lower-respiratory-tract infections; skin and soft tissue infections; and kidney, urinary tract, and bladder infections contributed most to these health disparities. Future prevention strategies should focus on high-risk regions and age groups, along with illnesses contributing to health disparities.

Phthalate exposure is ubiquitous and may affect child and adolescent health through both in utero exposure and direct exposure during childhood. Variability in exposure within women is not well documented. We analyzed 90 first-morning urine samples collected by ten reproductive-age women for phthalate metabolites and creatinine. Monoethyl [122 ng/mL (geometric mean concentration = 139 microg/g creatinine)], monobutyl [85.4 ng/mL (97.0 microg/g creatinine)], monobenzyl [37.2 ng/mL (42.2 microg/g creatinine)], and mono-2-ethylhexyl phthalate [9.4 ng/mL (10.7 microg/g creatinine)] were detected in most (94.4%) samples. The concentrations ranged from 23.8-1090 ng/mL, 43-437 ng/mL, 12.4-186 ng/mL, and 1.3-31.1 ng/mL, respectively. We observed considerable variation in phthalate concentrations by day for individual women. The intraclass correlation coefficient, indicating the proportion of variance explained by differences between subjects, ranged from 0.40 (monobutyl) to 0.68 (monoethyl). Monobenzyl and monoethyl phthalates showed higher levels on weekends as compared with weekdays (p = .01 for both). We found no significant difference between monoester levels from different menstrual cycles. Phthalate concentrations vary considerably for an individual and may require multiple samples for accurate assessment

OBJECTIVE: To describe the occurrence of Kawasaki syndrome (KS) among different racial/ethnic groups in Hawaii. METHODS: Retrospective analysis of children <18 years of age, with a focus on children <5 years of age, living in Hawaii who were hospitalized with KS using the 1996-2006 Hawaii State Inpatient Data. RESULTS: Children <5 years of age accounted for 84% of the 528 patients <18 years of age with KS. The average annual incidence among this age group was 50.4 per 100,000 children <5 years of age, ranging from 45.5 to 56.5. Asian and Pacific Islander children accounted for 92% of the children <5 years of age with KS during the study period; the average annual incidence was 62.9 per 100,000. Within this group, Japanese children had the highest incidence (210.5), followed by Native Hawaiian children (86.9), other Asian children (84.9), and Chinese children (83.2). The incidence for white children (13.7) was lower than for these racial/ethnic groups. The median age of KS admission for children <5 years of age was 21 months overall, 24 months for Japanese children, 14.5 months for Native Hawaiian children and 26.5 months for white children. CONCLUSIONS: The high average annual KS incidence for children <5 years of age in Hawaii compared to the rest of the United States population reflects an increased KS incidence among Asian and Pacific Islander children, especially Japanese children. The incidence for white children was slightly higher than or similar to that generally reported nationwide.

BACKGROUND: Perfluoroalkyl substances (PFAS) are a class of contaminants used in many industrial applications and consumer products. Certain PFAS are regulated or voluntarily limited due to concern about environmental persistence and adverse health effects. OBJECTIVES: In this analysis we examine PFAS levels and their association with metabolic syndrome and its components, using a representative sample of the U.S. METHODS: Data on PFAS levels and metabolic syndrome components were collected from the 2007-2008, 2009-2010, 2011-2012, and 2013-2014 cycles of the National Health and Nutrition Examination Survey. Twelve different PFAS were measured in serum samples from participants. Logistic regression models were used to identify associations between metabolic syndrome, its individual components, and serum PFAS concentrations. RESULTS: Over one-third (37%) of participants met the definition for metabolic syndrome, with increased waist circumference and elevated glucose being the most commonly reported components. Seven PFAS were detected in at least 30% of participants and were examined in subsequent analyses (PFDA, PFOA, PFOS, PFHxS, MPAH, PFNA, PFUnDA). The PFAS with the highest concentrations was PFOS (median 8.4â¯ng/mL), followed by PFOA, PFHxS and PFNA. After adjusting for potential confounders, PFNA was associated with increased risk of metabolic syndrome and well as several individual components, while the highest levels of PFHxS were associated with elevated triglycerides. Other PFAS were associated with decreased risk of at least one outcome. CONCLUSIONS: Associations between PFAS and metabolic syndrome are inconsistent within and across studies. PFNA was consistently associated with increased risk for components of the syndrome, a finding that warrants further investigation.

OBJECTIVES: The aim of the study was to describe mesothelioma occurrence in Wisconsin from 1997 to 2013 by usual industry and occupation (I&O), including occupations generally considered low risk. METHODS: Population-based rates and standardized incidence and mortality ratios were calculated. Two case-control analyses were designed to compare mesothelioma incidence and mortality in specific I&O groups with occurrence of (1) brain and central nervous system cancers and (2) other causes of death, using logistic regression. RESULTS: Mesothelioma incidence and mortality were elevated in Wisconsin (SIRadj = 1.20 [1.13 to 1.28]; SMRadj = 1.30 [1.22 to 1.38]). Certain industry (construction, manufacturing) and occupation (construction and extraction) groups were associated with increased odds of mesothelioma, with some evidence of increased risk among teachers. CONCLUSIONS: Forty years after the Occupational and Safety Health Act, mesothelioma incidence and mortality remain elevated in Wisconsin, with increased risk continuing for certain I&O groups.

OBJECTIVE: In March 2016, the state health departments of Wisconsin and Minnesota learned of three shipyard workers with blood lead levels (BLLs) more than 40âµg/dL. An investigation was conducted to determine the extent of and risk factors for the exposure. METHODS: We defined a case as an elevated BLL more than or equal to 5âµg/dL in a shipyard worker. Workers were interviewed regarding their symptoms and personal protective equipment (PPE) use. RESULTS: Of 357 workers, 65.0% had received more than or equal to 1 BLL test. Among tested workers, 171 (73.7%) had BLLmax more than or equal to 5âµg/dL. Workers who received respirator training or fit testing had a median BLLmax of 18.0âµg/dL, similar to the median BLLmax of workers who did not receive such training (22.6âµg/dL, Pâ=â0.20). CONCLUSIONS: Our findings emphasize the importance of adequate provision and use of PPE to prevent occupational lead exposure.

OBJECTIVE: Describe mercury exposures among women of childbearing age before and after an educational intervention. METHODS: Women age 18 to 45 were recruited to participate in an educational intervention concerning fish consumption. Fish consumption habits and total mercury concentration in hair were assessed pre- and post-intervention. Regression models examined associations between mercury, fish consumption, and demographics. RESULTS: Overall, 234 women completed the study. On average, mercury concentrations increased by 0.01âppm (parts per million) following the intervention, despite declines in fish consumption; however, women in the 90th percentile for mercury at baseline decreased concentrations significantly while maintaining high rates of fish consumption. Mercury concentrations were positively correlated with fish consumption and certain demographic characteristics. CONCLUSIONS: The intervention reached individuals most at-risk. Healthcare providers should discuss fish consumption habits with women to encourage consumption of low-risk fish, and identify women needing education and counseling.

OBJECTIVE: The aim of this study was to determine fish consumption habits and contaminant exposures associated with adverse cardiovascular outcomes among older male anglers. METHODS: One hundred fifty-four men aged 50 years and older living and fishing in Wisconsin completed a detailed survey and provided hair and blood samples. Associations between fish consumption and body burdens of several contaminants, with self-reported cardiovascular outcomes, were evaluated. RESULTS: Consuming fish species with higher methyl mercury content was positively associated with odds of angina, coronary heart disease (CHD), or heart attack, while consuming fattier species was negatively associated with high blood pressure or high cholesterol. Total mercury in blood was associated with 27% higher odds of heart attack, and certain classes of polychlorinated biphenyls were positively associated with CHD. CONCLUSION: Total mercury exposures may affect cardiovascular outcomes. Educational interventions promoting consumption of fish low in methyl mercury among older male anglers are needed.

OBJECTIVE: The aim of this study was to examine associations between endocrine disorders, fish consumption habits, and biomarkers of contaminants and nutrients METHODS: : Male anglers aged at least 50 years living in Wisconsin (nâ=â154) completed a questionnaire and provided biological samples. Adjusted logistic regression models were used to evaluate risk factors for endocrine outcomes. RESULTS: Nineteen percent of anglers reported either pre-diabetes or diabetes, while 4.6% reported thyroid disease. There were few associations between endocrine disease and fish consumption, fish meal source, or species, aside from a notable increase in diabetes risk with lake trout consumption. Docosahexaenoic acid, certain polychlorinated biphenyls (PCBs), and perfluorinated compounds were associated with an increased risk of diabetes or pre-diabetes. PCBs were associated with a decreased risk of thyroid disease. CONCLUSION: Fish consumption patterns may affect risk for endocrine outcomes, but direction and magnitude of association may depend on the balance of the contaminants and nutrients in the individual diet.

BACKGROUND: Perfluoroalkyl substances (PFAS) are an emerging class of contaminants. Certain PFAS are regulated or voluntarily limited due to concern about environmental persistence and adverse health effects, including thyroid disease and to dyslipidemia. The major source of PFAS exposure in the general population is seafood. OBJECTIVES: In this analysis we examine PFAS levels and their determinants, as well as associations between PFAS levels and self-reported health outcomes, in a group of older male anglers in Wisconsin with high fish consumption. METHODS: A biomonitoring study of male anglers aged 50 and older living in Wisconsin collected detailed information on fish consumption, demographics and self-reported health outcomes, along with hair and blood samples for biomarker analysis. Sixteen different PFAS were extracted from serum samples. Regression models were used to identify factors (demographic characteristics and fish consumption habits) associated with PFAS biomarker levels in blood, as well as associations between PFAS and self-reported health outcomes, adjusting for potential confounders. RESULTS: Seven PFAS were detected in at least 30% of participants and were used in subsequent analyses (PFDA, PFHpS, PFHxS, PFNA, PFOA, PFOS, PFuDA). The PFAS with the highest levels were PFOS, followed by PFOA, PFHxS and PFNA (medians of 19.0, 2.5, 1.8 and 1.4ng/mL). In general, increasing age was associated with higher PFAS levels, while increasing BMI were associated with lower PFAS levels. Greater alcohol consumption was associated with higher levels of PFHpS, PFHxS and PFOA. Associations with smoking and employment did not show a consistent pattern. Associations between fish consumption and PFAS were generally weak, with the exception of notably higher PFDA and PFHpS with both other locally-caught fish, and restaurant-purchased fish. Regarding associations with health outcomes, PFuDA, PFNA and PFDA were all associated with increased risk of pre-diabetes and/or diabetes. PFHpS was associated with a significantly increased risk of high cholesterol; PFDA and PFuDA also showed notable, though non-significant associations. All PFAS evaluated were associated with lower risk of hypertension although the only significant odds ratio was that for PFNA. There were no associations between any of the PFAS examined and either coronary heart disease, or the grouped outcome of any cardiovascular condition. CONCLUSIONS: PFAS are emerging contaminants with widespread exposure, persistence, and potential for adverse health effects. In this study population, demographic patterns may reflect differences in exposure sources, or possibly differences in adsorption and metabolism. PFAS were associated mainly with endocrine related outcomes, with a general trend towards increased risk of glucose intolerance and high cholesterol. Continued research on the risks and benefits of fish consumption is important due to potential exposure to PFAS and noted associations with highly prevalent adverse health outcomes.

Fish are an important source of nutrients which may reduce risk of adverse health outcomes such as cardiovascular disease; however, fish may also contain significant amounts of environmental pollutants such as mercury, polychlorinated biphenyls (PCBs), polybrominated diphenyl ethers (PBDEs), and perfluorinated compounds (PFCs, also called perfluoroalkyl compounds), which confer increased risk for adverse health effects. The Wisconsin Departments of Health Services and Natural Resources developed a survey instrument, along with a strategy to collect human biological samples to assess the risks and benefits associated with long-term fish consumption among older male anglers in Wisconsin. The target population was men aged 50 years and older, who fish Wisconsin waters and live in the state of Wisconsin. Participants provided blood and hair samples and completed a detailed (paper) questionnaire, which included questions on basic demographics, health status, location of catch and species of fish caught/eaten, consumption of locally caught and commercially purchased fish, and awareness and source of information for local and statewide consumption guidelines. Biological samples were used to assess levels of PCBs, PBDEs, PFCs (blood), and mercury (hair and blood). Quantile regression analysis was used to investigate the associations between biomarker levels and self-reported consumption of fish from the Great Lakes and other areas of concern, other locally caught fish, and commercially purchased fish (meals per year). Respondents had a median age of 60.5 (interquartile range: 56, 67) years. The median fish consumption was 54.5 meals per year, with most fish meals coming from locally-caught fish. Participants had somewhat higher mercury levels compared with the US general population, while levels of other contaminants were similar or lower. Multivariate regression models showed that consumption of fish from the Great Lakes and areas of concern was associated with higher levels of each of the contaminants with the exception of PBDEs, as was consumption of locally caught fish from other water bodies. All commercial fish consumption was also associated with both hair and blood mercury. When looking at specific PCB, PBDE and PFC analytes, consumption of fish from the Great Lakes and areas of concern was associated with higher levels of each of the individual PCB congeners examined, as well as higher levels of all of the PFCs examined, with the exception of PFHxS. Among the PFCs, locally caught fish from other water bodies was also associated with higher levels of each of the congeners examined except PFHxS. Finally, all commercial fish was associated with higher levels of PFHxS.

There is limited research on the combined effects of smoking and asbestos exposure on risk of localized pleural thickening (LPT). This analysis uses data from the Marysville cohort of workers occupationally exposed to Libby amphibole asbestos (LAA). Workers were interviewed to obtain work and health history, including ever/never smoking and chest X-rays. Cumulative exposure estimates were developed on the basis of fiber measurements from the plant and work history. Benchmark concentration (BMC) methodology was used to evaluate the exposure-response relationship for exposure to LAA and a 10% increased risk of LPT, considering potential confounders and statistical model forms. There were 12 LPT cases among 118 workers in the selected study population. The mean exposure was 0.42 (SD=0.77) fibers/cc-year, and the prevalence of smoking history was 75.0% among cases and 51.9% among non-cases. When controlling for LAA exposure, smoking history was of borderline statistical significance (P-value=0.099), and its inclusion improved model fit, as measured by Akaike's Information Criterion. A comparison of BMC estimates was made to gauge the potential effect of smoking status. The BMC was 0.36 fibers/cc-year, overall. The BMC for non-smokers was approximately three times as high (1.02 fibers/cc-year) as that for the full cohort, whereas the BMC for smokers was about 1/2 that of the full cohort (0.17 fibers/cc-year).

BACKGROUND: The present study describes the rate and trends of childhood hospitalizations with Kawasaki syndrome (KS) in the United States. METHODS: Retrospective analysis of hospitalizations with KS among children <18 years of age in the United States using the Kids' Inpatient Database (1997, 2000, 2003, and 2006) and the Nationwide Inpatient Sample (1998-2007). RESULTS: The KS-associated hospitalization rate for children <5 years of age was 20.8 (95% CI: 18.5-23.1) per 100,000 children in 2006. Annual rates remained constant during the study period, except for a peak in 2005. In 2006, 76.8% (SE = 0.9%) of an estimated 5523 (SE = 289) KS-associated hospitalizations among children <18 years of age were <5 years of age. The mean age for all children at hospitalization was 3.0 years (SE <0.1); 25.7 months (SE = 0.3) for children <5 years of age, and 24.8 months (SE = 0.4) and 27.1 months (SE = 0.5) for boys and girls, respectively. The rate for boys was higher than that for girls (24.2 [95% CI: 21.3-27.1] and 16.8 [95% CI: 14.7-18.9], respectively). The rate for Asian/Pacific Islander children (30.3 [95% CI: 20.2-40.4]) was the highest among the racial groups. CONCLUSIONS: The national KS-associated annual hospitalization rate for children <5 years of age from 1997 to 2007 was relatively stable and was similar to previously published rates, except for an increase in 2005. Most hospitalizations were in children <3 years of age with few hospitalizations during the first 2 months of age. Children of Asian/Pacific Islander descent had the highest hospitalization rate.

PURPOSE: Patterns of pubertal development reflect underlying endocrine function and exposures, and could affect future health outcomes. We used data from a longitudinal cohort to describe factors associated with breast and pubic hair stage and estimate average duration of puberty. METHODS: Data from the Avon Longitudinal Study of Parents and Children were used to describe timing and duration of pubertal development in girls. Self-reported Tanner stage of breast and pubic hair and menarche status were collected from ages 8-14 through mailed questionnaires. Factors associated with breast and pubic hair stage were identified using ordinal probit models. Age at entry into breast and pubic hair stages, and duration of puberty were estimated using interval-censored parametric survival analysis. RESULTS: Among the 3,938 participants, being overweight or obese, of non-white race, being the firstborn, and younger maternal age at menarche were associated with more advanced breast and pubic hair stages. Having an overweight or obese mother was associated with more advanced breast stages. Time spent in breast stages 2 and 3 was longer (1.5 years) than time spent in pubic hair stages 2 and 3 (1 year). The average age at menarche was 12.9 (95% CI, 12.8-12.9) years, and average duration of puberty (time from initiation of puberty to menarche) was 2.7 years. CONCLUSIONS: Girls in Avon Longitudinal Study of Parents and Children had a slightly longer duration of puberty compared to an earlier British cohort study. Various maternal and child characteristics were associated with breast and pubic hair stage, including both child and maternal body mass.
