Methods	Non‐randomized Controlled Study, two municipalities in the province of Aceh Indonesia
Participants	Inclusion criteria: Exclusion criteria: Age [Mean (SD)]—Intervention, Control: 28.4 (3.51), 28.2 (3.82) Occupation [n (%)]—Intervention, Control: Housewife: 67 (95.7), 65 (92.9) Working: 3 (4.3%), 5 (7.1) Education [n (%)]—Intervention, Control: 9th grades: 46 (65.7), 38 (54.3) 12th grades and higher: 24 (34.3), 32 (45.7)
Interventions	Intervention (n =) Description: Intervention for anemic pregnant women consisted of 2 home visits (45–60 min) from a well‐trained village government midwife. The period between the first home visit and the second home visit was 2 weeks. First home visit: individual education through the pictorial handbook. Second‐home visit: individual counseling. During the sessions, the midwife and women discussed how to improve the amount, variety, and frequency of iron‐rich food intake with consideration of price, preferences, and accessibility. Creating an atmosphere that supported IFA compliance, such as placing the tablet in an easily seen place, customizing the time of intake, asking the husband or a family member for a reminder and solving the IFA side‐effect problem. Nutrition counseling messaging: The information on IDA in the pictorial handbook consisted of definitions, signs and symptoms, causes and risk factors, and prevention and treatment, as well as foods rich in iron and recommendations on the intake of IFA tablets. There were pictures available to support the explanation, in addition to pictures of food rich in iron that are affordable, locally available, and recognized by the community. This visit emphasized the behaviors of iron‐rich food and IFA tablet intake, the benefits of and barriers to iron‐rich food and IFA tablet intake, how to cope with the barriers, and susceptibility to and severity of anemic pregnancy. The information and activities above were designed to fulfill the assumption of the HBM; that is, a person's beliefs about health are determinants of the possibility of the individual make changes in their lifestyle and behaviors. Intervention adapted to local context: The suitability of the handbook‚ that is, message content, literacy, pictures, and layout was evaluated through informal interviews with health professionals, including a doctor, a master of community nutrition, a Master of Health Education, and five village government midwives, selected for convenience. Due to the Islamic characteristics of society in Aceh, human figures in the book were depicted as Muslim and attached several quotes from the Quran in the handbook. Women empowerment approach: Partial empowerment model Control (n = 78) Description: On the other hand, anemic pregnant women in the control area received routine antenatal care without any further support such as that received by women in the intervention area.
