Objectives: Gastric cancer (GC) demonstrates a sex disparity that may also be associated with body mass index (BMI). This study explored whether the effect of BMI on the risk of GC varies by sex.

Methods: The study cohort included 341,999 Koreans aged 40 years or older from the National Health Insurance Service–Health Screening Cohort, with a median follow-up period of 10 years. Participants were categorized into five groups based on their BMI. The effect of BMI was evaluated using Cox proportional hazard regression. Additionally, stratification analysis was performed according to waist circumference.

Results: An increased risk of developing GC was observed across the study population among those with obesity (BMI 25.0–29.9 kg/m²; hazard ratio [HR], 1.11; 95% CI , 1.03–1.20) and severe obesity (BMI ≥30.0 kg/m²; HR, 1.22; 95% CI, 1.01–1.47), considering a 2-year latency period. Notably, the rise in GC risk was particularly pronounced among women with obesity and men with severe obesity. In the age-stratified analysis, severe obesity (BMI ≥30.0 kg/m²) was associated with an increased risk of GC in men under 50 years old (HR, 1.83; 95% CI, 0.99–3.37). For individuals aged ≥50 years, obesity was linked to a heightened risk of GC in both sexes. Furthermore, normal BMI (18.5–22.9 kg/m²) was associated with an increased GC risk in women.

Conclusion: These findings indicate a positive association between excess body weight and the risk of GC in Koreans, particularly among men with severe obesity.

Objectives

This study was conducted to determine the prevalence of hypertension in adolescents and to find the relationship between an increase of body mass index and waist circumference (WC) and blood pressure (BP).

Methods

Four hundred twenty-nine adolescents between the ages of 15 and 18 at high school in Seoul were enrolled and their anthropometric data and body composition were measured. BP was measured by oscillometric devices at least twice. Hypertension was defined according to the normative BP reference for Korean children and adolescents.

Results

The prevalence of prehypertension and hypertension was 14.0%, 9.2% in boys and 9.0%, 10.2% in girls. The prevalence of prehypertension and hypertension was 9.0%, 6.0% in the normal body mass index group, 14.6 %, 16.7% in the overweight group, 21.7%, 29.8% in the obese group. The prevalence of systolic hypertension was 3.6% in the normal group, 12.5% in the overweight group and 29.8% in the obese group. However, the prevalence of diastolic hypertension had significant differences between the groups, which were 3.3% in the normal group, 6.3% in the overweight group and 4.3% in the obese group. According to WC, the prevalence of hypertension was 6.2% in the below 75th percentile WC group, 22.2% in the75th to 90th percentile WC group and 25.6% in ≥90th percentile WC group. The risk of hypertension was 5.55 times higher in the obese group and 2.04 times higher in the overweight group, 3.93 times higher in ≥90th percentile of WC group.

Conclusion

The risk of hypertension is markedly increased with obesity in high school students.
