RESUMO
BACKGROUND: Lifestyle changes when transitioning from high-school to college expose students to unhealthy behaviors associated with high cardiovascular risk. The study aimed to assess the cardiovascular behavior metrics according to the AHA criteria, in freshman college adolescents from Northwest Mexico. METHODS: The study was cross-sectional. Demographics and health history were collected by questionnaires. Four behaviors were evaluated: diet quality using a duplicated FFQ, physical activity (PA) using the IPAQ, smoking, and body mass index (BMI) percentile; blood pressure was measured as a biological metric. Intakes were averaged and summed for each food group; sodium and saturated fat were calculated using the Mexican System of Food Equivalents or the USDA Database. Metrics were categorized into ideal, intermediate or poor level according to the AHA criteria. Diet outliers (± 3 SD) were trimmed and data was tested for normality. Mean±SD were calculated for continuous and percentages for categorical variables. Chi-square test compared the prevalence of demographic variables and levels of each cardiovascular metric by sex. Independent T-test evaluated differences in anthropometrics, dietary, and PA by sex, and the prevalence of ideal vs. non-ideal dietary intakes. RESULTS: Participants were n = 228, 55.6% men, age = 18.5±0.4 y. A higher prevalence of men indicated working, playing sports, and family history hypertriglyceridemia (p < 0.05). Men showed higher weight, height, BMI, waist, blood pressure, and lower PA and body fat (p < 0.05). Concerning diet quality, significant differences by sex were observed in nuts and seeds (1.1±0.6 and 0.9±0.6 oz/week, p = 0.042) and processed meats (749.8±639 and 503.6±300.3 g/week, p = 0.002); only fish and shellfish group reached AHA recommendations (513.1 ± 450.7 vs. 501.7 ± 428 g/week, p = 0.671) for men and women, respectively. Ideal level was reached by 70.9% participants for BMI percentile, 87% for smoking, 67.2% for blood pressure, 25.9% for PA, and 12.2% for diet score. Regarding food groups and nutrients, the lower prevalence in the ideal level was for sugar-sweetened beverages (10%, p = 0.013) and processed meats (4.8%, p = 0.208), and the highest for fish and shellfish (87.8%, p = 0.281) . CONCLUSIONS: The diet and PA patterns of Northwest Mexican freshman adolescents make them a high-risk group for developing long-term unhealthy habits and cardiovascular complications early in adulthood.

Los problemas relacionados con los trastornos metabólicos se han incrementado en la actualidad en población joven. Promover un estilo de vida saludable en estudiantes universitarios puede ayudar a prevenir diabetes, enfermedades cardiovasculares y diferentes tipos de cáncer. Objetivo. Calcular el Índice de Masa Corporal (IMC) de universitarios para identificar la prevalencia de obesidad e hipertensión como factores de riesgo metabólico. Materiales y método. Se utilizó muestreo probabilístico aleatorio simple (n= 282, edad 19,1 ± 1,8, 54,6% mujeres, 48,5% hombres). Se realizaron mediciones de peso y estatura para calcular el IMC, circunferencia de cintura y presión arterial. Resultados. Los resultados promedio para mujeres y hombres respectivamente fueron: IMC 24,0 ±5,5 y 25,2 ±5,2 kg/m2 (p= 0,25); cintura 76,25 ± 11,87 y 82,32 ± 15,85 cm (p= 0,001), indicando un riesgo bajo en 73,1% de mujeres y 82,5% de hombres; y presión arterial 127,73/86,03 y 142,3/94,2 mmHg (p= 0,001). La probabilidad de tener hipertensión arterial fue mayor al tener una relación cintura/estatura (RCE) alterada en mujeres y hombres (OR=3,037; IC95% 1,385-6,657 y OR=3,664; IC95% 1,249-2,179, respectivamente). Conclusiones. La población universitaria presenta factores de riesgo que pueden derivar en enfermedades crónicas no transmisibles en un futuro próximo, por lo cual es necesario modificar sus estilos de vida. La RCE es un buen predictor de riesgo de hipertensión en esta población(AU)
The problems related to metabolic disorders have now increased in the young population. Promoting a healthy lifestyle in college students can help prevent diabetes, cardiovascular disease, and different types of cancer. Objective. To calculate the Body Mass Index (BMI) in college students to identify the prevalence of obesity and hypertension as metabolic risk factors. Materials and methods. Simple random probability sampling was used (n = 282, age 19,1 ± 1,8, 54,6% women, 48,5% men). BMI was calculated with weight and height, waist circumference, and blood pressure. Results. The average results for women and men respectively were: BMI 24,0 ± 5,5 and 25,2 ± 5,2 kg/m2 (p = 0,25); waist 76,25 ± 11,87 and 82,32 ± 15,85 cm (p = 0,001), indicating a low risk in 73,1% of women and 82,5% of men; and blood pressure 127,73 / 86,03 and 142,3 / 94,2 mm Hg (p = 0,001). The probability of having arterial hypertension was higher when there was an altered waist / height ratio (WHR) in women and men (OR = 3,037; 95% CI 1,385-6,657 and OR = 3,664; 95% CI 1,249-2,179, respectively). Conclusions. The university population presents risk factors that could lead to chronic diseases. It is necessary to modify their lifestyles to prevent future diseases. WHR is a good predictor of hypertension risk in this population(AU)
