Data confidence 70 medium

How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

OBJECTIVE: Obesity has been recognized as a major public health problem globally. The COVID-19 pandemic has negatively affected behavioral patterns and, as a result, the weight gain of people around the world. We aimed to explore factors associated with perceived weight gain among the adult population of Kazakhstan during the COVID-19 pandemic. METHODS: A cross-sectional study using a multi-stage sampling approach was conducted in Kazakhstan in the summer of 2021. We collected socio-demographic characteristics, information about health-related factors, behavioral risk factors, and self-reported weight change during the pandemic. Multivariable logistic regression was performed to identify factors related to weight gain during the pandemic. Data were analyzed using SAS 9.4 Software. RESULTS: Among 931 participants, 20.95% (N = 195) of individuals gained weight. In the multivariable regression model, the weight gain was associated with increased snacking (AOR = 3.36, 95% CI: 2.20-5.12, p-value < .0001), decreased physical activity (AOR = 1.83, 95% CI: 1.24-2.70, p-value = 0.002), and increased alcohol consumption (AOR = 3.64, 95% CI: 1.72-7.70, p-value < 0.001). We found that older age (≥60 y.o.) was a protective factor for weight gain (AOR = 0.31, 95% CI: 0.15-0.62, p-value = 0.001). CONCLUSION: One-fifth of adults have gained weight during the COVID-19 pandemic which was associated with potentially modifiable unhealthy behavioral patterns. Our findings highlight that targeted health promotion strategies on global and national levels are needed to emphasize the avoidance of unhealthy behavioral patterns in times of crisis, like the COVID-19 pandemic.
