Objective: The prevalence of overweight and obesity is gradually increasing in both developed and developing countries. Obesity, for instance, can present multifactorial causes that interact with each other. Among the important factors, parental obesity plays a prominent role in the onset of obesity during childhood and teenage years through genetics and ambient aspects. This study aims to verify the possible existence of an association between overweight/obesity of schoolchildren and cardiovascular risk (CVR) factors for their parents.
Subjetcs and methods: For this purpose, a cross-sectional study was conducted with a sample of 1,243 children and adolescents, aged between 7 and 17. Out of the total number of participants, 563 (45.3%) were boys who were selected across 19 schools in the urban and rural areas of Santa Cruz do Sul, Rio Grande do Sul (Brazil). The overweight/obesity status of the schoolchildren was evaluated through their body mass index (BMI). Additionally, a self-reference questionnaire was employed to measure their parents' CVR.
Results: The results of this study revealed that students with overweight/obesity have a higher probability of having a father with hypertension (OR = 1.49; p = 0.038) and obesity (OR = 2.36; p = 0.002) and a mother with obesity (OR = 1.72; p = 0.016).
Conclusion: To conclude, this study confirms a relationship between overweight/obesity of schoolchildren with CVR for their parents.
