ABSTRACT
Objective
Several studies have been conducted on the relationship between breakfast consumption and mental health with conflicting results. Therefore, the present systematic review and meta-analysis was undertaken to summarize evidences on the association between skipping breakfast and mental health.
Methods
We searched online databases for all related papers through the comprehensive international data bases of Institute of PubMed/ MEDLINE, ISI/WOS and Scopus up to December 2019, using relevant keywords. Overall, 14 studies were included in this systematic review and meta-analysis.
Results
The total sample size of all selected studies was 399,550 individuals with age range of 6 to ≥65 years old. We found a significant positive association between skipping breakfast and Odds Ratio (OR) of depression (pooled OR: 1.39; 95% CI: 1.34–1.44), stress (pooled OR: 1.23; 95% CI: 1.04–1.43) and psychological distress (pooled OR: 1.55; 95% CI: 1.47–1.62). In contrast, there was no significant association between skipping breakfast and anxiety in all age cohort (pooled OR: 1.31; 95% CI: 0.97–1.65). However, subgroup analysis based on age stratification showed that there was a significant positive association between skipping breakfast and anxiety in adolescences (pooled OR: 1.51; 95% CI: 1.25–1.77).
Conclusion
In conclusion, skipping breakfast was positively associated with odds of depression, stress and psychological distress in all age groups and anxiety in adolescence, underlining impact of breakfast on mental health.
