Brief Summary

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.

Study Arms (1)

Cross-sectional assessment of adolescent girls

Adolescent girls' diet, nutritional status, socioeconomic conditions, and female autonomy, and climate change impacts on food access and nutrition will be assessed in two seasons.

Other: Assess natural behavior

Interventions

Assess natural behavior OTHER

No intervention

Also known as: No intervention

Cross-sectional assessment of adolescent girls

Eligibility Criteria

• Age: 12 Years - 17 Years
• Sex: female
• Healthy Volunteers: Yes
• Age Groups: Child (0-17)
• Sampling Method: Probability Sample

Study Population

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.

You may qualify if:

• 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

You may not qualify if:

• Any health condition that may affect anthropometric measurements
• Severe illness that may interfere with physical or biochemical assessments
