The moderating effect of gender on the relationships between obesity, well-being, and stress perception in Korean adolescents

Sex difference in nocturnal blood pressure dipping in adolescents with varying degrees of adiposity

BACKGROUND

For adolescents, abnormal dipping patterns in blood pressure (BP) are associated with early-onset organ damage and a higher risk of cardiovascular disorders in adulthood. Obesity is one of the most common reasons for abnormal BP dipping in young people. However, it is unknown whether the severity of obesity is associated with BP dipping status and whether this association is sex-dependent.

METHODS

499 participants between 12 and 17 years old with overweight or obesity underwent ambulatory blood pressure monitoring (ABPM) between April 2018 and January 2019 in Beijing and Baoding. Participants were grouped by body mass index (BMI) into overweight (BMI 85th-95th percentile), obese (BMI ≥ 95th percentile) and severely obese (BMI ≥ 120% of 95th percentile or ≥ 35 kg/m2) groups. Non-dipping was defined as a < 10% reduction in BP from day to night. The interaction effect between sex and obesity degree was also analyzed.

RESULTS

326 boys and 173 girls were included, of whom 130 were overweight, 189 were obese, and 180 were severely obese. Girls with severe obesity had a higher prevalence of non-dipping, but boys showed no significant differences in BP dipping status between obesity categories. In addition, as obesity severity went up, a more evident increase in night-time SBP was observed in girls than in boys.

CONCLUSIONS

Severely obese is associated with a higher prevalence of non-BP dipping patterns in girls than in boys, which suggests that the relationship between the severity of obesity and BP dipping status might be sex-specific.

Association between weight, weight perception, weight teasing and mental health among adolescents

BACKGROUND

Adolescent mental health problems are becoming increasingly prevalent, and there are correlations between weight-related concerns and adolescent mental health. The aim of this study is to explore the association between three weight-related factors (actual weight, weight perception, and weight teasing) and mental health problems (depressive symptoms, anxiety symptoms, and loneliness) in Chinese adolescents.

METHODS

10,070 adolescents between the ages of 11-18 from schools in Shanghai, China were selected using a stratified random cluster sampling method. Self-reported questionnaires were collected to investigate weight-related factors and mental health problems. Logistic regression analysis was used to examine the relationship.

RESULTS

The prevalence of depressive symptoms, loneliness, mild anxiety symptoms, and moderate to severe anxiety symptoms among adolescents were 18.0%, 53.8%, 26.5%, and 12.3%, respectively, with a higher prevalence found in females. After adjusting for weight perception and weight teasing, actual weight had no harmful impact on adolescents' mental health. Adolescents' perception of being overweight increased the risk of depressive symptoms, loneliness, mild anxiety symptoms, and moderate to severe anxiety symptoms, while the perception of being underweight had a similar but more profound impact (depressive symptoms OR = 1.590, 95% CI: 1.342-1.883; loneliness OR = 1.537, 95% CI: 1.353-1.746; mild anxiety symptoms OR = 1.368, 95% CI: 1.178-1.589; moderate to severe anxiety symptoms OR = 1.780, 95% CI: 1.449-2.186). Experiencing weight teasing more than once a year had a greater effect on adolescents' mental health, especially among adolescents with overweight/obesity (depressive symptoms OR = 2.970, 95% CI: 2.325-3.793; loneliness OR = 3.839, 95% CI: 3.119-4.727; mild anxiety symptoms OR = 2.822, 95% CI: 2.236-3.562; moderate to severe anxiety symptoms OR = 5.212, 95% CI: 3.846-7.065).

CONCLUSIONS

The prevalence of mental health problems among adolescents was high, especially loneliness. Weight perception and weight teasing, but not the actual weight, independently influenced adolescent mental health.

Application of the extended parallel process model and risk perception attitude framework to obesity knowledge and obesity prevention behaviors among Korean adults

BACKGROUND

Perceiving oneself as obese has been associated with weight loss attempts. However, such a perception may not sufficiently drive significant weight reduction in many individuals. Hence, relying solely on the traditionally emphasized perceived risk of behavioral changes in obesity is challenging. This study used an extended parallel process model and a risk perception attitude framework to explore the influence of perceived risk and perceived efficacy on individual obesity knowledge and obesity prevention behaviors.

METHODS

Data were obtained from 1,100 Korean adults aged 40-69 years through an online survey conducted in October 2022. Multinomial logistic regression and analysis of variance were employed to assess the relationships among perceived risk, perceived efficacy, obesity knowledge, and obesity prevention behaviors.

RESULTS

Sex was associated with being underweight, overweight, and obese. Moreover, perceived severity was associated with obesity, whereas perceived susceptibility was associated with overweight and obese. Response efficacy was related to being overweight alone, whereas self-efficacy was associated with being underweight, overweight, and obese. The main effects of sex and perceived risk, and their interaction effect were statistically significant for obesity knowledge. Additionally, the main effects of sex, perceived risk, and perceived efficacy on obesity prevention behaviors were statistically significant.

CONCLUSIONS

The extended parallel process model and risk perception attitude framework proved effective in classifying obesity based on body mass index, obesity knowledge, and obesity prevention behaviors.

Evaluation of maternal performance about food security in dietary diversity for children aged 12-24 months and its relationship with anthropometric measurements

BACKGROUND

Despite growing awareness of the problem of food security, some areas of Iran continue to experience food insecurity. The aim of the present study was to evaluate maternal performance about food security in dietary diversity for children aged between 12-24 months and its relationship with anthropometric measurements in Bushehr.

METHODS

A cross-sectional study was carried out using 400 mothers of children aged from 12 to 24 months in Bushehr selected via quota sampling. Data were collected using a reliable localized version of a 32-item food frequency questionnaire, consisting of six subscales, with a Cronbach's α: 0.81. The anthropometric measurements of height and weight were also calculated. Data analysis was performed using median, Mean±SD and multinomial logistic regression test, and odds ratio in SPSS, version 18.

RESULTS

According to standard servings, only 24% of the mothers fed their infants cereals, whereas 54.8%, 36.3%, 39.8%, and 20.3% of the mothers used meat, fruits, vegetables, and dairy products, respectively. The strongest associations were between attendance at educational classes and vegetable consumption (OR=2.09, CI=1.03-4.21), age at the onset of complementary feeding and the consumption of meat (OR=1.30, CI=1.02-1.66) and fruits (OR=1.44, CI=1.03-2.03), and the mothers' level of education and use of dairy products (OR=0.29, CI=0.09-0.90). No evidence of a significant association was found between consumption of any food groups and the anthropometric measurements.

CONCLUSIONS

Mothers in Bushehr performed poorly in providing their infants with the required nutrition with regard to dietary diversity and amount of food. However, their performance can be improved by enhancing their basic nutrition knowledge, holding practical classes on food preparation for them, and focusing on mothers with infants in high-risk groups, e.g. infants suffering from excessive weight gain, obesity, and malnutrition.

Lifestyle, psychological well-being, and body mass index of indigenous women

Lifestyle, psychological well-being, and body mass index of indigenous women. Introduction. Obesity is more common in women and has also been found to be present in indigenous populations. During university studies, obesity-related lifestyles are in the process of consolidation, and although this is known, research is limited to addressing physical activity and diet, ignoring other lifestyle components, such as life appreciation. Additionally, there is a need to corroborate whether psychological well-being contributes to excess weight in indigenous women. Objective. To determine whether there is an association between lifestyle, psychological well-being, and body mass index (BMI) in indigenous women. Materials and methods. A cross-sectional study was conducted among 110 female Zapotec university students in Juchitán, Oaxaca, Mexico. The Psychological Well-Being Scale, the Healthy Lifestyle Scale for University Students, and a questionnaire about personal data were used. Body weight and height were measured to calculate BMI. Results. There was a negative correlation between BMI, self-acceptance (r = -0.33; p < 0.01), and life appreciation (r = -0.22; p < 0.05). Positive correlations were found between lifestyle and psychological well-being dimensions, with the strongest correlations being observed between life appreciation and purpose in life (r = 0.55) and self-acceptance (r = 0.48). The multivariable models determined that life appreciation and self-acceptance are associated with BMI. Conclusion. Life appreciation and self-acceptance are predictors of BMI and are even more strongly associated than exercise and nutrition behaviors.
