RESUMO OBJETIVO: Analisar a associação entre atividade física durante a vida e fatores de risco cardiovasculares entre adultos. DESIGN: A amostra foi composta por 101 adultos (59 homens) entre 30 e 50 anos, os quais foram recrutados em diferentes academias de ginástica e uma universidade brasileira. Os participantes foram divididos de acordo com o engajamento prévio (autorrelatado) e atual de atividade física (mensurada por pedômetro) (participação esportiva durante a infância/adolescência e prática atual [n=26], participação esportiva durante a infância/adolescência e ausência de prática atual [n=26] e controle [n=49]). Como fatores de risco cardiovasculares foram mensurados gordura corporal (por meio de DXA), HDL, triglicérides, índice Homa, pressão arterial sistólica e diastólica, além da proteína c-reativa. Foram adotadas como covariáveis: idade cronológica, sexo, consumo de álcool e índice de massa corporal. Equações gerais de estimativa foram utilizadas adotando p<0,05. RESULTADOS: Após os ajustes no modelo final, indivíduos engajados em esporte durante a infância e adolescência e inativos durante a idade adulta apresentaram menor gordura corporal quando comparados com participantes persistentemente inativos (p<0,001). Participantes persistentemente ativos apresentaram menor gordura corporal (p<0,001) e proteína c-reativa (p=0,010) quando comparados ao grupo controle. CONCLUSÃO: Prática esportiva prévia (durante infância e adolescência) foi associada com redução da gordura corporal e ser fisicamente ativo ao longo da vida foi associado à redução da gordura corporal e proteína c-reativa.

SUMMARY OBJECTIVES: To analyze the association between physical activity during life and cardiovascular risk factors among adults. DESIGN: The sample was composed of 101 adults (59 men) between 30 and 50 years old, who were recruited from different gyms and from a University in Brasil. Participants were divided according to their engagement in sports in early life (self-reported) and current physical activity (pedometer) (sports participation during childhood/adolescence and currently active [n=26], sports participation during childhood/adolescence and currently inactive [n=26], and control [n=49]). Cardiovascular risk factors were measured, such as body fat (through DXA), HDL-C, triglycerides, HOMA index, systolic blood pressure, diastolic blood pressure, and C-reactive protein. We adopted the covariates of chronological age, sex, alcohol consumption, tobacco, and body mass index. General estimating equations were used, with p<0.05. RESULTS: After the adjustments of the final model, individuals engaged in sports during childhood and adolescence and inactive during adulthood presented lower body fat, when compared to participants persistently inactive (p<0.001). Participants persistently active presented lower body fat (p<0.001) and lower c-reactive protein (p=0.010) when compared to the control group. CONCLUSION: Early sports participation was associated with reduced body fat, and being physically active throughout life was associated with reduced body fat and C-reactive protein.

Abstract AIM The aim of this longitudinal study was to analyze the relationship between sleep disorder and intima-media thickness. METHOD Baseline measurements included carotid intima-media thickness, assessed by an ultrasound device; questionnaires about sleep and other behavioral variables; physical activity was measured by pedometer; body fatness was estimated by Dual-Energy X-ray Absorptiometry; fasting glucose, lipid profile and C-reactive protein were collected. RESULTS The occurrence rate of sleep-related disorders was 47% (95%CI= 37.2%-56.7%). Carotid intima-media thickness was related to symptoms of insomnia (r= 0.328 [0.141 to 0.493]) and, after adjustments for potential confounders, the relationship between carotid intima-media thickness and insomnia remained statistically significant (β= 0.121 [95%CI= 0.017; 0.225]). CONCLUSIONS In young adults, sleep disorder was significantly related to premature increase in carotid intima-media thickness.
