Dietary determinants of aflatoxin B1-lysine adduct among infants in Nepal.

BACKGROUND: Aflatoxins are mycotoxins produced by naturally occurring fungi on food, and aflatoxin B1 (AFB1) is carcinogenic, immunotoxic and hepatotoxic. This study assesses the relationship between AFB1 in Nepali infants at 12 months of age and their diet at 9 and 12 months of age. METHODS: The study used data collected from 1329 infants enrolled in the AflaCohort Study. Aflatoxin exposure was assessed at 12 months using serum AFB1-lysine pg/mg albumin biomarker measured using high performance liquid chromatography-fluorescent detection. Dietary data were collected using food frequency questionnaire. We conducted ordinary least squares and quantile regression analyses with backward elimination to assess lagged (9-month diet and 12-month AFB1) and contemporaneous (12-month diet and 12-month AFB1) associations. RESULTS: Eighty-one percent of children at 12 months had detectable levels of serum AFB1-lysine (geometric mean: 0.79 pg/mg albumin, 95% CI: 0.74-0.83). The levels ranged from 0.4 to 85 pg/mg albumin. Dietary diversity at 9 and 12 months were not associated with serum AFB1-lysine levels. Consumption of fish and groundnuts at both 9 and 12 months and infant formula and cauliflower at 9 months were associated with higher serum AFB1-lysine while consumption of bananas and mangoes at 12 months were negatively associated with serum AFB1-lysine (p < 0.05). CONCLUSIONS: High prevalence of detectable AFB1-lysine among infants, and possible links to their dietary patterns argues for more urgent research into which foods in children's diets are most contaminated, and into optimal entry points in the food chain that would allow for effective actions to minimize exposure.

Violence and sexual and reproductive health service disruption among girls and young women during COVID-19 pandemic in Nepal: A cross-sectional study using interactive voice response survey.

INTRODUCTION: There is a paucity of data on the impact of COVID-19 pandemic on girls and young women. The study examines the prevalence and correlates of violence and sexual and reproductive health (SRH) service disruption among girls and young women during COVID-19 restrictions and lockdown. METHODS: An interactive voice response survey was conducted among girls and women aged 18-24 years between 10th March to 24th April 2021. The survey enrolled 1314 participants. Descriptive analysis was used to assess prevalence of violence and SRH service disruption. Two sampled test of proportion was used to asses difference in prevalence of violence before and after the pandemic. Logistic regression was used to examine relationship between the outcome variables and socio demographic predictors. RESULTS: The study did not find significant difference in prevalence of violence before and after the pandemic. Education was found to be protective against experience of both physical and sexual violence after the pandemic. Dalit participants were four times more likely to report physical violence after the pandemic than Brahmin/Chhetri participants (OR:3.80; CI:1.41-10.24). Participants from 22-24-year age group were twice as likely to experience sexual violence compared to girls and participants from 18-21year age group (OR:2.25; CI:1.04-4.84). Participants from urban municipalities were 29% less likely to report SRH services disruption than participants from rural municipalities (OR-0.71, 95% CI: 0.55-0.91). Participants with disability were twice as likely to report disruption than participants without disability (OR-2.35, 95% CI: 1.45-3.82). CONCLUSIONS: To reduce violence against girls and women due to the pandemic, interventions should focus on Dalit women and on preventing education discontinuation among girls and women. SRH service during the pandemic needs to be improved for girls and women with focus on girls and women from rural municipalities and girls and women with disability.

Factors Associated with Anemia among Pregnant Women of Underprivileged Ethnic Groups Attending Antenatal Care at Provincial Level Hospital of Province 2, Nepal.

BACKGROUND: This study aims at determining the factors associated with anemia among pregnant women of underprivileged ethnic groups attending antenatal care at the provincial level hospital of Province 2. METHODS: A hospital-based cross-sectional study was carried out in Janakpur Provincial Hospital of Province 2, Southern Nepal. 287 pregnant women from underprivileged ethnic groups attending antenatal care were selected and interviewed. Face-to-face interviews using a structured questionnaire were undertaken. Anemia status was assessed based on hemoglobin levels determined at the hospital's laboratory. Bivariate and multiple logistic regression analyses were used to identify the factors associated with anemia. Analyses were performed using IBM SPSS version 23 software. RESULTS: The overall anemia prevalence in the study population was 66.9% (95% CI, 61.1-72.3). The women from most underprivileged ethnic groups (Terai Dalit, Terai Janajati, and Muslims) were twice more likely to be anemic than Madhesi women. Similarly, women having education lower than secondary level were about 3 times more likely to be anemic compared to those with secondary level or higher education. Women who had not completed four antenatal visits were twice more likely to be anemic than those completing all four visits. The odds of anemia were three times higher among pregnant women who had not taken deworming medication compared to their counterparts. Furthermore, women with inadequate dietary diversity were four times more likely to be anemic compared to women having adequate dietary diversity. CONCLUSIONS: The prevalence of anemia is a severe public health problem among pregnant women of underprivileged ethnic groups in Province 2. Being Dalit, Janajati, and Muslim, having lower education, less frequent antenatal visits, not receiving deworming medication, and having inadequate dietary diversity are found to be the significant factors. The present study highlights the need of improving the frequency of antenatal visits and coverage of deworming program in ethnic populations. Furthermore, promoting a dietary diversity at the household level would help lower the prevalence of anemia. The study findings also imply that the nutrition interventions to control anemia must target and reach pregnant women from the most-marginalized ethnic groups and those with lower education.
