Diabetes and associated dietary intake among urban adults: COPEN (Colombian Nutritional Profiles)—a cross-sectional study

Abstract

ObjectivesDiabetes is increasing rapidly in low-income and middle-income countries. We aimed to estimate the prevalence of diabetes, describe its correlates and its associated dietary intake in urban adults from Colombia.SettingThe Colombian Study of Nutritional Profiles was a population-based, cross-sectional, multi-stage probabilistic sampling survey designed to represent the five main Colombian cities.ParticipantsBetween June and November 2018, we studied 736 non-pregnant participants aged 18 or older. Diabetes was defined as a random plasma glucose ≥200 mg/dL, self-reported prior diagnosis of diabetes or use of any oral or injectable antidiabetic medication(s). Participants also fulfilled a detailed 157-item food-frequency questionnaire.Primary and secondary outcome measuresPrevalence of diabetes, dietary intake of key nutrients, achievement of dietary goals among individuals with diabetes.ResultsThe overall estimated prevalence of diabetes was 10.1%, with no difference by sex (9.6% in women, 10.8% in men, p=0.43). The association between diabetes and education level depended on sex, diabetes was more prevalent among more educated men and less educated women. Abdominal obesity was associated with a 65% increase in diabetes prevalence among men, and a 163% increase in women. Individuals with diabetes reported lower mean consumption of all nutrients, but after adjustment by sex, age, socioeconomic level (SEL) and body mass index, only their lower sodium consumption remained significant (p=0.013). The proportion of non-achievement of dietary intake goals among participants with diabetes was 94.4% for saturated fats, 86.7% for sodium, 84.4% for fibre and 80% for trans fats. In multivariate logistic regression models, age was the strongest independent correlate of diabetes.ConclusionsDiabetes by self-report, random plasma glucose or medication use was highly prevalent among Colombian adults. There were large differences by abdominal obesity status, region of residence, SEL and educational level. The proportion of individuals with diabetes meeting dietary recommendations was alarmingly low.

“…Diabetes is a severe chronic disease that affects around 422 million individuals worldwide [6], with the highest prevalence observed in countries with low and middle-income populations. Colombia, with an estimated population of 50 million, has a diabetes prevalence rate of around 10,1% [7]. The International Diabetes Federation estimates that the current prevalence of diabetes in Colombia is 9,9% [8].…”

Impact of metabolic control on all-cause mortality in a nationwide cohort of patients with diabetes from Colombia

“…Over the recent years, diabetes seems to be on the rise in Colombia. Despite a scarcity of large population-based data, the prevalence among adult urban residents was estimated at about 10% in 2018 (1,17). In addition, diabetes holds an important place as a cause of mortality in Colombia (8 th place (18)) and countries of a similar sociodemographic and cultural background.…”
