Nutritional status girls Bangladesh
Nutritional status of adolescent girls by the salinity and seasonality. BMI-for-age of adolescent girls was measured during dry (August to September 2017) and wet (April to May 2018) season. Different agro-aquatic ecological zone- HS, High saline; MS, Medium saline; LS, Low saline; FW, Fresh water, and PP, Processing plant.


Former IMMANA Grantee David Little co-authored a new paper entitled: "Factors affecting the micronutrient status of adolescent girls living in complex agro-aquatic ecological zones of Bangladesh". This study assessed multiple micronutrient status including vitamin D, iron, vitamin A, and urinary iodine concentration among adolescent girls through two seasonal cross-sectional surveys conducted during dry and wet seasons.

The majority of Bangladeshi women have their first child before reaching the age of eighteen years, which influences both the maternal and child health. Fish is significantly a good source of dietary protein and micronutrients in low- and middle-income countries. Given the importance of aquatic foods in ecological zones, the researchers sought to study how these delicate eco-systems affect the seasonal nutrition and health status of adolescent girls.

The researchers conducted a mixed-linear and logistical regression analysis to assess associations between nutrient status, salinity and seasonality. Vitamin (OH)D insufficiency was significantly higher in freshwater areas in wet season compared to dry season (wet season: 58% and dry season: 30%). The authors also found that the odds of vitamin (OH)D insufficiency was eleven times higher in fresh water areas compared with high saline areas.

In conclusion, despite the environment being enriched with micronutrient-contained aquatic food, adolescent girls in coastal areas experience different micronutrient deficiencies. Attention should be paid to the high rates of vitamin (OH)D insufficiency, particularly in freshwater areas, and seasonal iron deficiency in the high saline zones.

The government may consider food fortification on some essential foods, distribution and utilization of Various Micronutrient Supplements and Ready-to-Use Supplementary and Therapeutic Foods. In agriculture, they may used hydroponics and others to produce their own vegetables. The community should be aware of proper way of cooking their foods micronutrients especially vitamins are easily removed by over cooking. The income of family instead of eating their harvested fresh seafoods they sell it and bought unhealthy foods.
