title: Early Signs of Atherogenesis in Adolescents in a Havana Family Medicine Catchment Area.
abstract: INTRODUCTION Atherosclerosis is the common underlying cause of cardiovascular diseases; the leading cause of morbidity and mortality globally. It is a major contributor to disability and poorer quality of life and is costly to health systems, individuals, families and society. Early signs of atherogenesis are manifestations of atherosclerosis and known atherogenic risk factors occurring at young ages and detectable by health professionals. Early detection of such signs in children and adolescents enables actions to prevent short- and long-term complications. OBJECTIVE Detect early signs of atherogenesis in adolescents in Family Doctor-and-Nurse Office No. 13 of the Raúl Gómez García Polyclinic in Havana's 10 de Octubre Municipality. METHODS An observational, cross-sectional descriptive study was conducted: the universe consisted of 110 adolescents and, once exclusion criteria were applied, the sample was made up of 96 adolescents in the office's geographical catchment area. Variables included sociodemographic data; measurements from physical and anthropometric examinations (weight, height, body mass index, waist circumference, blood pressure, presence of acanthosis nigricans); maternal history of diabetes mellitus and hypertension, smoking during pregnancy; birth weight and duration of exclusive breastfeeding; lifestyle (physical activity, dietary habits by frequency of consumption of fruits and vegetables, salt intake, and smoking); and a history of atherogenic risk factors and atherosclerotic diseases (hypertension, diabetes mellitus, heart disease, cerebrovascular disease, peripheral arterial disease and chronic kidney disease) in adolescents and their families. The number of early signs of atherogenesis was determined. Descriptive statistics and a chi-square test, with significance threshold set at p = 0.05, were used to examine differences by sex and age. RESULTS A total of 62.5% of participating adolescents were female and the same percent of the total were in early adolescence. Prevalent risk factors were poor dietary habits (81.3%), passive smoking (54.2%) and sedentary lifestyle (45.8%). The latter was more frequent among female and adolescents aged 10-14 years. Prehypertension and active smoking were prevalent during late adolescence. Hypertension was the disease most often found in family history (91.7%). All adolescents had at least one early sign of atherogenesis, and 72.9% had ≥3 signs, noted especially in female participants. CONCLUSIONS The high prevalence of ≥3 early signs of atherogenesis in this study suggests the need to initiate primary prevention before onset of adolescence, and even prior to birth, using a gender perspective, to conduct educational interventions designed to change the risk factors highlighted in the study and reduce cardiovascular risk in adolescents.
