Determinants of nutritional knowledge, attitude, and practice among southwestern Iranian households: A community-based study

Background: Malnutrition is generally due to a lack of nutritional information rather than food deficiency. Therefore, the current knowledge, attitudes, and practice (KAP) of the target audience should be evaluated to eliminate malnutrition. However, KAP varies across demographic status and socioeconomic status (SES). Aim: The associations of nutritional KAP with demographic and socioeconomic variables were evaluated among households living in urban and rural areas of southwestern Iran. Methods: A cross-sectional, population-based study was conducted on 842 household heads (492 urban and 350 rural) using a standardized NUTRIKAP Household Questionnaire. The data evaluating nutritional KAP as well as demographic and socioeconomic information were obtained using a multi-stage cluster sampling method. SES score was also computed. Results: Urban households had a higher level of nutritional knowledge (p < 0.05) but a lower level of nutritional attitude (p < 0.001) and practice (p < 0.001) compared with the rural ones. Rural households with the poorest quintiles of SES were 0.4 times less likely to have good nutritional knowledge (adjusted odds ratio = 0.4, confidence interval: 0.2, 0.9; p < 0.05), compared with higher quintiles. Households with an over-60-years-old household head had significantly higher nutritional attitude (p < 0.05) and practice (p
