Lead In Food And Its Correlation With Blood Lead Levels Among Pregnant Women Of Sindh, Pakistan.

BACKGROUND: With increasing control of lead (Pb) in gasoline, food has emerged as an important secondary pathway for Pb exposure globally. This study assessed Pb levels in food duplicates and blood. Furthermore, it assessed the correlation of Pb in food duplicates and blood Pb levels with common food items taken by pregnant women of Sindh, Pakistan. METHODS: A cross-sectional study was conducted from August 2014 to November 2015, in urban (Karachi) and rural (Gambat, Khairpur) area of Sindh-Pakistan. A total of 103 venous blood samples (Karachi = 63 and Gambat = 40) of pregnant women were measured for blood Pb levels at the time of delivery. One month post-delivery, food frequency questionnaire (FFQ) was administered and three-day food duplicates (same number of cooked portions of food eaten by women) were collected. Food duplicates were analysed for Pb levels. Multivariable linear regression was conducted to identify the frequency of food items which contribute to blood and food Pb levels of pregnant women, separately. RESULTS: With 90% confidence interval, chapati (local flat bread) (ß=0.20, p<0.001), boiled rice (ß=0.35, p<0.001), cooked root vegetables (ß= 0.16, p=0.03), fried savory items (ß=0.15, p=0.03), sweet snacks (ß=0.13, p=0.08) were positively associated with elevated mother blood Pb levels. While cream biscuits (ß =-0.14, p=0.04), lassi (blend of yogurt, water and spices) (ß= -0.31, p<0.01), market milk desserts (ß=-0.22, p<0.001), fish (ß= -0.16, p=0.02), soft drinks (ß= -0.19, p=0.01) and supari/gutka (betel-nut) (ß=-0.13, p= 0.06) were negatively associated with mother Pb levels. Tetra-pak market juices (ß= 0.30, p<0.001) and cooked root vegetables (ß=0.19, p=0.05) were positively associated with mother food Pb levels, at 90% CI. CONCLUSIONS: Bread, boiled rice, fried savoury items, sweet snacks and cooked root vegetables were contributing to blood Pb levels of pregnant women in Pakistan. These food items may be contaminated with Pb during processing, packaging and storage. Inverse relation of Supari/gutka and soft drinks with blood Pb levels may be due its overall reduction in absorption capacity of the gut for nutrients. Objective individual food item analysis for Pb is warranted for further intervention.

Dietary practices of school children in Sindh, Pakistan.

BACKGROUND: Malnutrition in Pakistan has remained an unresolved issue for decades. Data on nutrient intake and variety in children's diet is lacking. AIM: This paper describes the dietary practices of school children across eight districts of Sindh. METHODS: A school-based survey of dietary practices among 1109 students from classes 2-5 in 36 schools was conducted using a pre-tested interviewer-completed questionnaire. RESULTS: Descriptive and comparative analysis of data showed that more than 75% school children ate breakfast, lunch and dinner regularly. However, 10% children skipped breakfast and nearly one-third of them skipped mid-morning and evening snacks. Skipping breakfast and snacks was related to low socio-economic status and rural residence. Children's intake of protein-rich food items and fruits also illustrated that urban residence and better socio-economic status have a positive effect on the frequency and variety of daily protein and fruit intake. Though affordability and geographic location were key determinants of children's dietary practices, significantly higher percentages of children studying in class 2, 3 and 4 consumed different kinds of protein-rich food items, fruits and vegetables more frequently as opposed to children studying in class 5. Junk food consumption was more common in urban areas and better socio-economic strata. CONCLUSION: Development of school-based nutrition education programmes and behavior change strategies emphasizing the regular intake of meals and nutrient-rich snacks, and encouraging consumption of easily available and affordable food items such as dried seeds, fruits, vegetables, milk and its derivatives is essential for addressing nutrient deficiencies.

PERSPECTIVES REGARDING ANTENATAL CARE, DELIVERY AND BREAST FEEDING PRACTICES OF WOMEN FROM BALUCHISTAN, PAKISTAN.

BACKGROUND: Antenatal Care is one of the fundamental rights for women to safeguard their health. Neonatal mortality rates have remained relatively static, compared to the decline in infant and under 5 mortality rates, adverse practices regarding breast feeding and pre-lacteal feeds being the important factors responsible. This study aimed to explore the Antenatal Care, delivery and breastfeeding practices in three districts of Baluchistan. METHODS: It was a qualitative phenomenological design using Constructivist approach. The study was conducted in three districts of Baluchistan province, Gwadar, Quetta, Qila Saifullah. There were a total of 14 Focus Group Discussions with women regarding Antenatal Care, delivery and Breastfeeding practices, followed by audio taping, transcription as verbatim and analysis through Nvivo version 2. A process was deployed for identification and reporting of the components in order to ensure quality and validity of the qualitative findings. RESULTS: Across the sites, women attended ANC at least once. However, their descriptions of ANC often varied. The women preferred Dais instead of doctors, due to the affordability, customs and availability. A lack of trained doctors and long distances to get a check-up lead to home deliveries in the study setting. Colostrum was discarded by majority of the mothers, while prelacteal feed was a common practice. CONCLUSION: This paper has explored factors affecting ANC attendance, delivery and breast feeding practices across three settings. Both the demand and supply side factors have an important influence on practices.
