Risk of noncommunicable diseases and associated factors in Algerian adolescents (10–19 years old)

Abstract

ObjectiveNoncommunicable diseases (NCDs) are a public health problem and their prevalence is increasing worldwide at an alarming rate. The objective of this study was to assess the predictive factors for NCDs in adolescents. Material and methodsThe study included adolescents enrolled in public establishments in Constantine (east of Algeria). Demographic variables, health variables, smoking, anthropometry, diet, and physical activity were assessed by means of a questionnaire. All data were analyzed using the software R 3.2.4. The significance threshold was set at 95%. ResultsThe sample consisted of 1,222 adolescents (56.1% girls) aged 10–19 years. Overall, 8.6% had NCDs; 23.2% were overweight (obesity included). The frequency of consumption was insufficient for dairy products and fruits and vegetables (p=0.0000) and the opposite was found for fatty and sugary products (p=0.0000). A total of 82.8% had been breastfed. Physical activity recommendations were not followed. Risk factors for the development of NCDs were family history of these diseases (odds ratio [OR]=2.89), active smoking (OR=3.18), passive smoking (OR=2.03), fetal macrosomia (OR=1.40), time in front of screens ≥3 h/day (OR=1.28), and overweight (OR=1.15). The consumption of fatty and sweet products was positively correlated with weight status (r=0.258; p=0.0000). Protective factors were breastfeeding for ≥ 6 months (OR=0.69) and moderate physical activity of ≥60 min/day (OR=0.38). ConclusionAdolescents presented predictors factors for NCDs due to harmful behaviors to their health.
