Sleep duration and physical activity were associated with healthy eating habits among Peruvian secondary school students, with students sleeping 7 hours having higher odds of healthy eating and students with low physical activity having lower odds of healthy eating.
Key Findings
Results
Students who slept 7 hours had significantly higher odds of having healthy eating habits compared with those who slept 6 hours or less.
Adjusted odds ratio (aOR) = 2.525; 95% CI: 1.181–5.536; p = 0.018
Analysis was performed using multivariable binary logistic regression
Study population consisted of 275 secondary school students aged 12 to 17 years in Peru
Sleep duration was assessed using a validated questionnaire
Results
Students with low levels of physical activity showed lower odds of having healthy eating habits compared with those with high levels of physical activity.
Adjusted odds ratio (aOR) = 0.097; 95% CI: 0.005–0.564; p = 0.032
Physical activity level was assessed using a validated questionnaire
The comparison was between low physical activity and high physical activity groups
Association was identified through multivariable binary logistic regression analysis
Methods
The study was conducted among Peruvian secondary school students using an observational, analytical, cross-sectional design.
Sample size was 275 secondary school students
Age range was 12 to 17 years
Sleep duration, physical activity, and eating habits were all assessed using validated questionnaires
Associations were analyzed using both Pearson's chi-square test and multivariable binary logistic regression
Background
A considerable proportion of Peruvian school students do not meet recommended levels of physical activity and may also experience insufficient sleep.
The authors identified insufficient sleep and inadequate physical activity as potentially negatively affecting eating habits among this population
These behavioral factors were described as 'key behavioral components in the development of healthy lifestyles during adolescence'
The study context was Peru, where these lifestyle deficiencies were noted as a public health concern among school-aged youth
Conclusions
The authors concluded that integrated school-based strategies jointly addressing sleep, physical activity, and nutrition are important during adolescence.
Findings were interpreted as supporting the promotion of multi-component school-based interventions
The recommendation was to address sleep, physical activity, and nutrition together rather than in isolation
The target population for such strategies was identified as adolescents in the school setting
What This Means
This research examined whether sleep duration and physical activity levels are linked to healthy eating habits in Peruvian middle and high school students. The study surveyed 275 students between the ages of 12 and 17, asking them about their sleep, exercise habits, and what they eat. Researchers then used statistical methods to determine whether these behaviors were related to one another.
The study found two notable associations. First, students who slept 7 hours per night were about 2.5 times more likely to have healthy eating habits compared to students who slept 6 hours or less. Second, students who had low levels of physical activity were much less likely to have healthy eating habits compared to those who were highly active. These findings held up even after accounting for other factors through statistical adjustment.
This research suggests that sleep, exercise, and diet during the teenage years are interconnected behaviors rather than independent ones. Because all three factors appear to cluster together, programs aimed at improving adolescent health may be more effective if they address sleep, physical activity, and nutrition at the same time, rather than targeting each one separately. The authors point to schools as a practical setting for implementing such combined approaches.
