Relationship Between Sleep Duration and Overweight/Obesity: A Comprehensive Overview of Meta-Analyses Mateus Assis Benfica, Tamiles Costa Ribeiro, Kallyane Santos Oliveira Silva, Marcelle Reis Nascimento Oliveira, Ericka Luanny Machado Maia, et al. Clinical Obesity, 2026 Overweight and obesity are increasing globally and have an important impact on individuals' health and healthcare costs. Several factors contribute to this growth, and changes in normal sleep duration (SD) have been recognised. This relationship has given rise to numerous systematic reviews with meta‐analyses (SRMAs) over the last years. Thus, synthesising these studies could help researchers and clinicians offering the highest level of evidence synthesis. Therefore, we aimed to provide a comprehensive overview of SRMAs that explored the relationship between SD and overweight/obesity. Searches were conducted in PubMed, Web of Science, Embase and Scopus. The quality of the reviews was evaluated using the Risk Of Bias In Systematic reviews (ROBIS) tool. The inverse variance heterogeneity model (IVhet) was adopted to assess the pooled relative risks (RR) and 95% confidence intervals (CIs) of SRMAs. After the selection process, 18 SRMAs were included in the synthesis. Short SD increased the risk of being overweight/obese in younger children (RR = 1.39; 95% CI: 1.27–153), older children (RR = 2.21; 95% CI: 1.59–3.07), adolescents (RR = 1.36; 95% CI: 1.22–1.51) and adults (RR = 1.30; 95% CI: 1.17–1.44). Long SD increases the risk in adults (RR = 1.05; 95% CI: 1.02–1.08), but has a protective effect in children (RR = 0.86; 95% CI: 0.78–0.95). These findings reinforce the role of SD as a significant and modifiable risk factor for overweight and obesity.
Criterion Validity and Reliability of the IPAQ-SF for Assessing Sedentary Behavior in Adults Using Different Accelerometer Cut-Off Points Tamiles Costa Ribeiro, Ana Luiza Oliveira Santos Nascimento, Marcelle Reis Nascimento Oliveira, Aritana Pereira Ramos, Marcus Edson Carilo de Mello Vieira, et al. Perceptual and Motor Skills, 2026 This study aimed to investigate the criterion validity and reliability of the International Physical Activity Questionnaire - Short Form (IPAQ-SF) for estimating sedentary behavior (SB) across different time contexts (weekdays, weekends, and total weekly time) and using different accelerometer cut-off points. A total of 80 university students (73.7% women; mean age 26.0 ± 6.2 years) from a public higher education institution in Bahia, Brazil, participated in this methodological validation study. Sedentary time was objectively measured using an ActiGraph wGT3X-BT accelerometer over seven consecutive days, applying two cut-off points (<100 and <150 counts per minute). Self-reported sitting time was obtained using the IPAQ-SF, and test-retest reliability was assessed in a subsample of 20 participants after 14 days using the intraclass correlation coefficient (ICC). Criterion validity was examined using Spearman’s correlation and Bland-Altman analysis. The IPAQ-SF demonstrated moderate to almost perfect reliability (ICC = 0.622-0.856). Criterion validity was weak but statistically significant when using the <150 cpm cut-off for weekdays and total weekly sedentary time. Bland-Altman analysis indicated that the IPAQ-SF underestimated sitting time by 56% (≈214 min/day) at <100 cpm and overestimated it by 17.8% (≈117 min/day) at <150 cpm. Correlations were stronger for weekdays than weekends. In conclusion, the IPAQ-SF showed excellent reproducibility but limited criterion validity, highlighting the need for cautious interpretation of self-reported sedentary behavior in population-based studies.
