Stunting and Combined Overweight with Stunting among Schoolchildren in Kuwait: Trends over a 13-Year Period.

objectivesThis study aimed to investigate the sex- and age-specific trends of stunting and combined overweight with stunting among schoolchildren over a 13-year period in Kuwait. SUBJECTS AND

methodsThe Kuwait Nutrition Surveillance System objectively measured the height of 172,573 schoolchildren (5-19 years) over a 13-year period (2007-2019). Data on gender and date of birth were extracted from school records. Stunting was defined as height 2 standard deviations (SD) below the World Health Organization growth reference median. Logistic regression models were used to examine the trends of stunting over the study period while stratifying by gender.

resultsIn males, the prevalence of stunting increased from 2.46% in 2007 to 4.18% in 2019 (p for trend <0.001). In females, the prevalence of stunting fluctuated but remained around 3.80% in both 2007 and 2019. The odds of stunting significantly increased in the period 2017-2019 compared to the period 2007-2010 among males, adjusted odds ratio (AOR) 1.04 (95% confidence interval [CI]: 1.14-1.76); p = 0.009, but not females, AOR 0.89 (95% CI: 0.73-1.07); p = 0.176. Although not statistically significant, there was a tendency for the odds of combined overweight with stunting to increase in males, AOR 1.65 (95% CI: 0.90-3.04); p = 0.087, but not females, AOR 1.13 (95% CI: 0.88-1.45); p = 0.248.

conclusionAlthough the prevalence of stunting and combined stunting with overweight is low, there is an emerging upward trend in schoolboys that warrants further investigation and monitoring. This highlights the need for gender-specific interventions to reduce nutritional abnormalities in high-income countries in the Middle East countries like Kuwait.
