Development of a bioelectrical impedance analysis-based prediction equation for body composition of rural children aged 4-8 years in Myanmar.

Background: Reliable and accurate estimates of body composition are essential when studying the various health correlates of disease. Bioelectrical impedance analysis (BIA) is an affordable and feasible body composition assessment technique for clinical and field settings. Total body water (TBW) and hence fat-free mass is estimated by predictive regression algorithms using anthropometric measurements plus the resistance index. Aim: The study aimed to develop a BIA prediction equation for TBW in children in Myanmar using the deuterium dilution technique as the reference method. Methods: The study design was cross-sectional in a school setting with convenience sampling of participants. One hundred and two healthy children (57 boys and 45 girls) with aged 4 and 8 years participated; randomly divided into the prediction group (29 boys and 22 girls) and cross-validation group (28 boys and 23 girls). Whole-body impedance, anthropometric and TBW (by D2O dilution) measurements. The prediction equation was cross-validated using a split-group design and compared to published equations for contemporaneous populations. Results: TBW could be predicted by the following equation. TBW = 0.4597 * Weight (kg) + 0.1564 * Impedance index + 0.6075 (R2 = 0.891, P < 0.0001) with a correlation coefficient of 0.942 and limits of agreement of 0.98 kg TBW on cross-validation. Conclusions: This equation can be used to predict body composition in young (aged 4-8 years) children in Myanmar but because the age range of the participants in the present study was relatively narrow, more research in different age groups is required to establish its broader applicability.

Scaling Up Breastfeeding in Myanmar through the Becoming Breastfeeding Friendly Initiative.

BACKGROUND: Optimal breastfeeding practices in Myanmar are above global averages, and the Ministry of Health and Sports (MoHS) has demonstrated its commitment to support nutrition and breastfeeding through continued policy and program actions. In 2017, the MoHS, in partnership with Save the Children, led the piloting of the Becoming Breastfeeding Friendly (BBF) Initiative. BBF provides a guide for countries to assess the enabling environment for breastfeeding and a country's readiness to scale up breastfeeding policies and programs. OBJECTIVE: The aim of this study was to document the BBF process and outcomes in Myanmar. METHODS: A Working Group (WG) of 14 members, led by a chair and 2 cochairs, conducted the BBF assessment using the BBF Index (BBFI), generated and prioritized recommendations, and disseminated the findings over the course of 5 meetings. Additional meetings were held to gain stakeholder endorsement and approval of the BBF process and WG before commencement and MoHS endorsement of the findings. RESULTS: The BBFI score for Myanmar was 1.2 out of 3.0, which indicates a moderate environment for scaling up breastfeeding policies and programs. The Funding and Resources gear earned the lowest score (0.5), whereas Political Will earned the highest score (2.0). Overall, 4 gears were weak and 4 were moderate in strength. Nine recommendation themes were generated and prioritized. The top priority recommendation was to form a National Infant and Young Child Feeding Alliance. The MoHS endorsed the 9 recommendations in December 2018 and has provided leadership for the formation of the alliance. CONCLUSIONS: The BBF Initiative was successfully conducted in Myanmar, resulting in 9 prioritized recommendations for strengthening the breastfeeding enabling environment and substantial interagency collaborations. Adaptations to the BBF process were made for the context, and we note numerous lessons learned that should be considered by other countries that plan to commit to the BBF Initiative.

Calcium Intake among Myanmar Residing in Bago, Kayin, and Yangon Areas.

A cross-sectional survey combined with 24-hour dietary recall and food diary was undertaken to assess the calcium intake of the Myanmar population. The study was conducted from November 2003 to October 2005. A total of 886 subjects of both sexes aged above 2 years from three States and Divisions (Bago, Kayin, and Yangon) of Myanmar were included in the study. The major measures were mean daily calcium intake (mg/day) and major sources of calcium in the diet. Overall mean calcium intake was 197+13mg/day (2-9 years), 421+2mg/day (10-19 years), 399+21 mg/day (20-49 years), and 383+25mg/day (>50 years) for males, while the corresponding values for females were 207+17 mg/day, 366+19 mg/day, 387+16 mg/day, and 327 +19 mg/day. Calcium intake was less than 80% of the recommended dietary allowances (RDA) for Myanmar for ages 2-9 years and 10-29 years in all the study areas, and for the 50 years and above age group in Yangon. Fish paste was found to be the major source of calcium. Milk and milk products contributed very little to total calcium intake, contributing 2.1% for residents in Yangon, 5.1% in Pa-an and none in Bago. Consumption of calcium rich foods, particularly milk and milk products, should be encouraged among the Myanmar people. Towards this end, appropriate nutrition education materials should be developed for promotional purposes.
