Individual Food Consumption/Dietary Survey [hh/ifcs]
The overall aim of the project was to contribute to the development of preventive strategies for obesity and chronic noncommunicable diseases (NCDs) in the context of nutrition transition. The specific objectives were:
- Characterize the nature and magnitude of the double burden of malnutrition at household level.
- Assess the magnitude of the double burden of overweight and micronutrient deficiency, in particular iron deficiency at the individual level.
- Estimate the prevalence of overweight, obesity, biological and behavioral risk factors for diet-related noncommunicable diseases.
- Investigate behavioral-associated risk factors including physical activity and diet quality.
- Characterize the psycho-sociocultural determinants of obesity and chronic noncommunicable diseases (NCDs).
Sample survey data [ssd]
Individuals
Scope
The survey collected information on:
- SUBJECTS: information on the participants such as age, sex and geographical location
- CONSUMPTION: information on all foods consumed by each participant in each survey day, including quantities and nutrient values
Coverage
Sub-national coverage, both urban and rural areas.
The population groups covered were children, adolescents, and adults between 10 and 50 years of age.

Sampling
The study was a cross-sectional survey conducted between March 2009 and January 2010. The sample size was calculated using the prevalence of double burden (obesity + anaemia) among women aged 20 to 49 years as the main variable to be estimated by the survey. The setting accounted for a precision of 2 percent, a type I error risk (alpha) equal to 5 percent, a cluster effect of 2, and a non-response rate of 5 percent. According to the Population and Housing Census of 2004, the population of women aged 20 to 49 years represents approximately 23 percent of the total population, and the average household size is equal to 4.53 persons. Based on these parameters, 1511 households were required, resulting in a sampling rate of 1 in 328 households.
Sampling was carried out by the National Institute of Statistics using a two-stage stratified random sampling method. In the first stage, 76 census districts were sampled with probability proportional to size. In the second stage, twenty eligible households (i.e. featuring at least one woman aged between 20 and 49 years) were randomly selected in each district, and all individuals aged 10 to 49 years living in the household were included.
Weighted coefficients were calculated taking into account the characteristics of the sampling plan and the response rates.

In this study, dietary intake was assessed using a 3-day food record (two weekdays and one weekend day) to collect the types and amounts of meals, foods, and beverages consumed. Trained dieticians visited the selected households to give participants detailed information about the objectives and the process of the survey, as well as instructions on how to record the amount of food consumed using household tableware. Dieticians emphasized to respondents the importance of not changing their eating habits. The first step of the 3-day food record was self-administered by the subjects at home. The day of the survey, dieticians reviewed unclear descriptions, errors, omissions, or doubtful entries in the filled pre-printed form and asked the participants to clarify them. For each dish, a list of ingredients, the estimated weight of the raw edible portion and method of preparation were collected from the women in charge of food preparation. Information was collected on the state of the food consumed (as purchased, raw edible part, cooked edible portion). The accuracy of portion size of consumed foods was checked using photos of food portions and known weight/specific portions.
