Age

18 Years to 30 Years

Inclusion criteria

Inclusion criteria: Nulliparous and non-pregnant female garment workers aged 18-30 years.

Exclusion criteria

Design outcomes

Primary

Measure	Time frame
Body weight: Measured at baseline and endline (after 6 month) to the nearest 0.01kg using a SECA-UNICEF scale (SECA, Hamburg, Germany).	—

Secondary

Measure	Time frame
BMI, triceps skinfold thickness & mid-upper arm circumference: Measured at baseline and endline. Body height will be measured using a calibrated height scale. A non-stretchable measuring tape will be used to measure mid-upper arm circumference. A skinfold caliper will be used to measure triceps skinfold thickness. Iron, VitA, folate & VitB12 status: Measured at baseline and endline. Ferritin, soluble transferrin receptor, C-reactive protein, alpha-1-acid glycoprotein and retinol-binding protein concentrations will be determined by enzyme-immunoassays. Plasma folate and vitamin B12 concentrations will be determined using a commercial radio-immunoassay. Elevated C-reactive protein & alpha-1-acid glycoprotein concentrations, will be used to indicate the presence of subclinical inflammation/infection. Anemia: Measured at baseline and endline. Using a HemoCue HB301 photometer (HemoCue, Ängelholm, Sweden). Handgrip strength: Measured at baseline and endline. Will be measured in a sitting position using a Jamar handgrip dynamometer (Lafayette Instruments). Morbidity: Measured at baseline, endline and after 3 months, using a pre-tested semi-quantitative questionnaire collecting data on illness history within the last 2 weeks prior the survey.	—
