(P13-038-24) Characteristics of Korean Women With High BMI According to Clusters of Lifestyle Factors: Interim Analysis

Objectives: The objective of this study is to identify characteristics of Korean women with high body mass index (BMI) according to clusters of eight lifestyle factors including diet quality, food addiction, physical activity, depression, anxiety, alcohol drinking, morningness-eveningness, and total energy intake.

Methods: This study is currently in progress, aiming to recruit 600 adults with a BMI of 25 or higher and examine weight change patterns according to lifestyle factors. This interim analysis included a total of 406 women who completed the baseline questionnaires and weight measurements out of the 460 recruited participants. K means cluster analysis was performed using eight obesity-related lifestyle variables, including depression, anxiety, food addiction, alcohol consumption, morningness-eveningness, physical activity levels, total energy intake and diet quality. Least-squares means and standard errors adjusted for age were calculated using the GLM procedure.

Results: Two clusters, characterized by unhealthy and healthy lifestyle patterns, were identified. Compared to the healthy lifestyle pattern group, the unhealthy lifestyle pattern group was younger (32.0±7.1 vs. 35.7±8.9; p < .0001) and had higher levels of depression scores (11.0±0.4 vs. 4.0±0.4; p < .0001), anxiety scores (9.1±0.4 vs. 2.9±0.4; p < .0001), food addiction scores (4.1±0.2 vs. 0.9±0.2; p < .0001), alcohol consumption (1.5±0.1 vs. 0.8±0.1 frequency/week; p</em> < .0001), and total energy intake (2359.5±60.1 vs. 1675.2±60.7 kcal/day; p < .0001), while they had significantly lower morningness-eveningness scores (11.3±0.2 vs. 14.0±0.2; p < .0001), physical activity levels (31.9±4.9 vs. 53.6±4.9 METs hours/day; p=0.0021) and modified dietary approaches to stop hypertension (DASH) scores (19.4±0.3 vs. 22.5±0.3; p < .0001). However, there was no significant difference in BMI between two groups (29.9±0.3 vs. 29.5±0.3; p=0.2469).

Conclusions: Our interim analysis of Korean women with high BMI identified two distinct clusters of lifestyle patterns known to be associated with obesity.
