Factors associated with overweight and central adiposity in urban workers covered by the Workers Food Program of the Brazilian Amazon Region

OBJETIVO: Investigar os fatores associados ao sobrepeso e a obesidade abdominal em trabalhadores de ambos os sexos. METODO: Estudo transversal de base populacional, de uma amostra representativa de 1054 trabalhadores, com idade entre 18 e 74 anos, assistidos pelo Programa de Alimentacao do Trabalhador na regiao metropolitana de Belem do Para, na regiao norte do Brasil. Parâmetros relacionados a saude e medidas antropometricas foram obtidas e amostra de sangue foram coletadas. RESULTADOS: A prevalencia de sobrepeso foi de 38% nas mulheres e 50,4% nos homens. Dentre os individuos com sobrepeso, 6,1% das mulheres eram obesas e 10,7% dos homens tinham obesidade. Analise multivariada foi utilizada para identificar os fatores sociocomportamentais e clinico-bioquimicos associados com o aumento da adiposidade corporal (IMC > 25kg/m2 e circunferencia de cintura > 80cm para mulheres e >94cm para homens). As variaveis e a razao de prevalencia (PR) associadas ao sobrepeso e adiposidade abdominal nos homens foram: idade (1,02), renda familiar alta (1,05), fumo (1,36), hipertensao (pressao arterial sistolica 1,41 e pressao arterial diastolica 1,85) e hipertrigliceridemia (2,29). Nas mulheres as razoes de chance para sobrepeso e adiposidade abdominal foram: idade (1,02), consumo de alcool (1,42), hipertrigliceridemia (1,44), pressao arterial diastolilca (1,65) e hiperglicemia (1,71). CONCLUSAO: A associacao do sobrepeso e obesidade abdominal com parâmetros sociocomportamentais devem ser corrigidos com medidas educativas e preventivas. Alem disso, a associacao de sobrepeso e obesidade abdominal com parâmetros clinicos e bioquimicos coloca os trabalhadores de Belem do Para, assistidos pelo Programa de Alimentacao do Trabalhador, em possivel risco de morbidades e mortalidade precoce pelo aumento de adiposidade corporal.OBJECTIVE To investigate factors associated with overweight and abdominal obesity in male and female workers. METHODS This is a cross-sectional population-based study. A representative sample of 1,054 workers ranging from 18 to 74 years of age, selected among individuals covered by the Workers´ Food Program living in the Metropolitan region of Belém, Northern Brazil. Health-related behavior and anthropometry were assessed. Fasting blood samples were collected. RESULTS Overweight prevalence was 38.0% among women and 50.4% among men. Among overweight subjects, there were 6.1% obese women and 10.7% obese men. Multivariate analysis was used to identify social behavior and clinical-biochemical factors associated with increased body adiposity (BMI > 25 kg/m² and increased waist circumference: > 80 cm for women and > 94 cm for men). Variables positively and significantly associated with overweight and abdominal obesity in men according to prevalence ratio (PR) values were: age (1.02), high family income (1.05), smoking (1.36), hypertension (systolic blood pressure, 1.41; diastolic blood pressure, 1.85) and hypertriglyceridemia (2.29). In women, the PR of increased body adiposity was associated with: age (1.02), alcohol intake (1.42), hypertriglyceridemia (1.44), diastolic blood pressure (1.65) and hyperglycemia (1.71). CONCLUSIONS The association of overweight and abdominal obesity with social behavior variables should be corrected with preventive and educational measures. Furthermore, association of overweight and abdominal obesity with clinical and biochemical variables places the urban workers from the Amazon region assisted by the Workers´ Food Program at a possible risk for morbidity and mortality from increased body adiposity.
