Background: During May–June 2010, a childhood lead poisoning outbreak related to gold ore processing was confirmed in two villages in Zamfara State, Nigeria. During June–September of that year, villages with suspected or confirmed childhood lead poisoning continued to be identified in Zamfara State.Objectives: We investigated the extent of childhood lead poisoning [≥ 1 child with a blood lead level (BLL) ≥ 10 µg/dL] and lead contamination (≥ 1 soil/dust sample with a lead level > 400 parts per million) among villages in Zamfara State and identified villages that should be prioritized for urgent interventions.Methods: We used chain-referral sampling to identify villages of interest, defined as villages suspected of participation in gold ore processing during the previous 12 months. We interviewed villagers, determined BLLs among children < 5 years of age, and analyzed soil/dust from public areas and homes for lead.Results: We identified 131 villages of interest and visited 74 (56%) villages in three local government areas. Fifty-four (77%) of 70 villages that completed the survey reported gold ore processing. Ore-processing villages were more likely to have ≥ 1 child < 5 years of age with lead poisoning (68% vs. 50%, p = 0.17) or death following convulsions (74% vs. 44%, p = 0.02). Soil/dust contamination and BLL ≥ 45 µg/dL were identified in ore-processing villages only [50% (p < 0.001) and 15% (p = 0.22), respectively]. The odds of childhood lead poisoning or lead contamination was 3.5 times as high in ore-processing villages than the other villages (95% confidence interval: 1.1, 11.3).Conclusion: Childhood lead poisoning and lead contamination were widespread in surveyed areas, particularly among villages that had processed ore recently. Urgent interventions are required to reduce lead exposure, morbidity, and mortality in affected communities.

BACKGROUND We describe the prevalence of behaviors that put American Indian and Alaska Native (AI/AN) high school students at risk for teen pregnancy and sexually transmitted infections (STIs) and the relationships among race/ethnicity and these behaviors. METHODS We analyzed merged 2007 and 2009 data from the national Youth Risk Behavior Survey, a biennial, self-administered, school-based survey of US students in grades 9–12 (N =27,912). Prevalence estimates and logistic regression, controlling for sex and grade, were used to examine the associations between race/ethnicity, and substance use, and sexual risk behaviors. RESULTS Of the 26 variables studied, the adjusted odds ratios (AOR) were higher among AI/AN than White students for 18 variables (ranging from 1.4 to 2.3), higher among AI/AN than Black students for 13 variables (ranging from 1.4 to 4.2), and higher among AI/AN than Hispanic students for 5 variables (ranging from 1.4 to 1.5). Odds were lower among AI/AN than Black students for many of the sexual risk-related behaviors. CONCLUSIONS The data suggest it is necessary to develop targeted, adolescent-specific interventions aimed at reducing behaviors that put AI/AN high school students at risk for teen pregnancy, STI/HIV, and other health conditions.

Incarcerated American Indian/Alaska Native (AI/AN) women have multiple physical, social, and emotional concerns, many of which may stem from adverse childhood experiences (ACE). We interviewed 36 AI/AN women incarcerated in the New Mexico prison system to determine the relationship between ACE and adult outcomes. ACE assessment included physical neglect, dysfunctional family (e.g., household members who abused substances, were mentally ill or suicidal, or who were incarcerated), violence witnessed in the home, physical abuse, and sexual abuse. The most prevalent ACE was dysfunctional family (75%), followed by witnessing violence (72%), sexual abuse (53%), physical abuse (42%), and physical neglect (22%). ACE scores were positively associated with arrests for violent offenses, lifetime suicide attempt(s), and intimate partner violence.

Recommendations for STD control in this population include improved local surveillance and incorporation of existing frameworks of health and healing into prevention and intervention efforts. Research defining the parameters of cultural context and social epidemiology of STDs is necessary.
