Knowledge, Attitude and practice of households and health care staff towards nutrition and micronutrients (NUT-KAP) in provinces under the pilot study on flour fortification with Iron: study design and sampling method

A "healthy human being" is the cornerstone of stable development in every country. Thus, an important part of the development process is the nutritional improvement of the society. Although a great proportion of the familie's income is spent on food, nutritional problems are still prominent in this country. This fact demonstrates that diets are mostly influenced by the education and knowledge of the households, rather than any new developments in food production. This study was designed to investigate the knowledge, attitude and practices of the households and health care providers regarding nutrition and micronutrients in provinces of Boushehr, Golestan, and Sistan and Balouchestan. The results of this study can help the Community Nutrition Office in the design and effective implementation of interventions aimed at improving nutritional health in households. The sampling method for households was the single-stage cluster sampling with equal-sized clusters. The sampling method for health staff was stratified random sampling. The number of samples in each stratum was proportion to its size. A total of 2304 households and 360 health care workers were selected for this study.The data were gathered through a structured questionnaire and via interviews with eligible people in each household, and also some levels of health staff. At the level of the health staff, physicians and other health professionals, data collection was done through self-administered questionnaires.
