Abstract
Background: A common recommendation is to reduce the consumption of snack food and replace this consumption with nutrient-dense foods. The objective was to establish whether there were changes in adherence to the consumption of the snack pattern (SP) in Colombian children and adults in the 2010-2015 quinquennium. In addition, this study aimed to establish the relationship between the SP and some biological, socioeconomic, and geographic variables in Colombia, Sur América. Methods: Based on a Food Frequency Questionnaire (FFQ) applied both in 2010 and 2015 in the national nutritional situation surveys, the adherence to the snack consumption pattern was established through factor analysis. The change in the adherence of consumption to the SP was established for the five-year period [2015 minus 2010], using multiple linear regression models. Crude and adjusted differences were estimated by the following covariables: sex, age, marital status, food security, wealth index, ethnicity, education of the head of the household, area and region. In total, 37,981 subjects were analyzed. In 2010, 10,150 children (5 to 17 years old) and 5,145 adults (18 to 64 years old) were included, and in 2015, 13,243 children and 9,443 adults. Results: In children, the adjusted difference in the adherence to SP was -0.37 (95% CI: -0.42, -0.32), p < 0.0001. In adults, the adjusted difference in the adherence to SP was -0.27 (95% CI: -0.31, -0.24), p < 0.0001. In all categories of covariables, consumption decreased, for all p < 0.0001. In children the decrease in consumption was inversely associated with body mass index (BMI) and height and was directly associated with the level of food security in the home and the wealth index. In adults the decrease in consumption was inversely related to age and BMI and directly related to the size, the level of food security of the household, wealth index, and education level. Conclusions: In the quinquennium there is a decrease in the adherence to the SP, the region, the wealthiest, the tallest, the best BMI and the most educated displayed the greatest decrease in the SP.
