This study examines how seafood consumption, social changes, and climate change affect the nutrition and well-being of adolescent girls in south-western Bangladesh. Many adolescent girls face poor nutrition, early marriage, and limited access to adequate diets. Adolescent girls have high nutritional needs due to growth and potential early motherhood. Seafood, including fish, shrimp, and prawns, provides important nutrients such as omega-3 fatty acids, but little is known about how its consumption relates to nutritional status in this population.
The study will collect new data from adolescent girls in the same area as a 2017 study (IMMANA study), assessing dietary pattern, nutritional status, socioeconomic conditions, and female autonomy. It will also explore how climate change affects household food access and nutrition to provide policies linking food systems and public health.
Adolescent girls aged between 12-16 years
Residing in the same study area as the 2017 IMMANA study
Willing to participate and provide informed consent
Any health condition that may affect anthropometric measurements
Severe illness that may interfere with physical or biochemical assessments
The study will recruit 300 adolescent girls aged 12-16 years from the same study area as the 2017 IMMANA study. This will allow comparison of changes over the past 10 years in dietary patterns, nutritional status, fish consumption, and micronutrient status including blood levels of omega-3 fatty acids.

Fish consumption pattern over the last seven days
Fish consumption patterns will be assessed using a 7-day food frequency questionnaire. Higher fish consumption is expected to correspond to better omega-3 status among the adolescent girls.
Dietary pattern assessment
Dietary patterns will be assessed using a 7-day food frequency questionnaire. The number of food groups consumed will be calculated. In general consuming ≥5 food groups out of 10 is considered the minimum threshold for the dietary diversity score although this depends on age.
Female autonomy
Female autonomy will be assessed using a standardized female autonomy questionnaire. Autonomy will be scored based on a total of 32 items covering seven domains. Higher scores indicate greater female autonomy.
