Psychosocial Predictors of Body Weight Congruence in Adolescents Aged 15 and 17 Years in Poland: Findings from the Health Behaviour in School-Aged Children (HBSC) Study. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2022; 19:ijerph19042342. [PMID: 35206529 PMCID: PMC8872581 DOI: 10.3390/ijerph19042342] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 12/30/2021] [Revised: 02/16/2022] [Accepted: 02/17/2022] [Indexed: 01/25/2023]
Abstract
Background: Body weight congruence (BWC) has implications for adolescent health. The main goal of this study was to examine the distribution of BWC and its relationship with six psychosocial factors. Methods: A representative sample of N = 3508 adolescents aged 15 and 17 years (52.4% girls) derived from the Health Behaviour in School-aged Children study, conducted in 2017/2018 in Poland, was used. BWC groups were defined based on self-reported BMI and subjective assessment of weight: (1) correct perception; (2) overestimation, and (3). underestimation. Principal component analysis (PCA) extracted the following two factors: a socio-relational factor (SR) related to perceived social support and social self-efficacy, and a body attitudes and social media exposure factor (BAME). Using the total sample, multinomial logistic regression was applied to estimate their impact on the BWC, and gender-specific models were compared. Results: Half (48.6%) of the adolescents correctly estimated their body weight, 31.0% overestimated it (girls 43.9%, boys 17.1%), and 20.0% underestimated it (boys 37.2%, girls 9.0%). Overestimation of body weight concerns 48.0% of normal weight girls, 50.0% of underweight girls, and 21.3% and 32.1% of normal weight and underweight boys, respectively. The percentage of normal weight (34.4%), and overweight and obese (30.8%) boys who underestimated their body weight was three times higher than the respective percentages of girls that underestimated their weight (9.0% and 11.9%). The SR factor protected adolescents from both underestimation (only in girls) and overestimation in the total sample (OR 0.74, 95%CI 0.68–0.81) and both genders. BAME increased this risk of overestimation in both genders (OR = 1.83, 95%CI 1.67–2.0), and the risk of underestimation among boys. Conclusions: Prevention programmes should include a wide range of psychosocial factors to improve BWC among adolescents.

Abstract
OBJECTIVE Weight-based victimization (WBV) involves being the target of intentional physical, verbal, or psychological harm because of one's body weight. Youth experience harmful health consequences from WBV, but this literature has neglected sexual and gender minority (SGM) youth, despite their high rates of overweight and obesity, and mental health problems. The present study assessed health behaviors (substance use), self-rated health, perceived control over stressors, depressive symptoms and self-esteem as a function of WBV in a large, national sample of LGBTQ (lesbian, gay, bisexual, transgender, and queer) adolescents. METHOD Participants (N = 9,838, Mage = 15.6 years, SD = 1.26) completed a web-based battery of questionnaires examining victimization, health, family, and school experiences of LGBTQ adolescents in the United States. RESULTS WBV was associated with increased odds of alcohol use, binge drinking, marijuana use, and cigarette use, independent of adolescents' age, race, body mass index (BMI), sexual identity, gender identity, caregiver education, and U.S. region. Frequency of WBV at school and weight teasing from family members were both consistently associated with lower self-rated health, lower perceived control over stressors, lower self-esteem, and higher depressive symptom scores. CONCLUSIONS These findings present the first large-scale evidence of the relationship between WBV and adverse health behaviors in SGM youth. Sexual minority youth who experience WBV, especially from family members, may be vulnerable to adverse health behaviors and low perceived health, regardless of their BMI. These findings highlight the importance of considering WBV when examining health behaviors in LGBTQ youth, and increased awareness of these issues among health care professionals.

Puhl RM, Himmelstein MS. Weight Bias Internalization Among Adolescents Seeking Weight Loss: Implications for Eating Behaviors and Parental Communication. Front Psychol 2018; 9:2271. [PMID: 30519207 PMCID: PMC6258789 DOI: 10.3389/fpsyg.2018.02271] [Citation(s) in RCA: 35] [Impact Index Per Article: 5.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/27/2018] [Accepted: 11/01/2018] [Indexed: 12/21/2022] Open
Abstract
Background: Emerging evidence has demonstrated a high prevalence of weight bias internalization (WBI) among adults, as well as consistent links between internalization and adverse psychological and physical health. However, research examining WBI in youth and its impact on their health is scarce, especially among youth seeking weight loss treatment who may be particularly vulnerable to weight stigma from peers and parents. To address this research gap, the present study assessed WBI in a weight loss treatment-seeking sample of adolescents, examining associations between internalization and adolescents' eating behaviors and parental weight-related communication. Methods: Adolescents (N = 148, M age = 15.97 years), completed online self-report measures to assess WBI (using the modified version of the WBI Scale), body weight, binge eating, eating as a coping strategy, and weight teasing from peers and family members. Adolescents also reported on the frequency of parental comments about body weight, parental dieting, and parental encouragement of adolescent dieting. Results: Adolescents expressed a high mean level of internalized weight bias (M = 5.45, SD = 0.88). Higher levels of internalization were observed across increasing body weight categories; no differences were observed for gender or history of weight teasing. WBI was significantly higher among adolescents who reported binge eating and eating to cope with distress. Regression analyses showed that weight-related comments from mothers (but not fathers) significantly predicted adolescents' WBI (including frequency of mothers' comments about adolescents' body weight, comments about their own body weight, and encouragement of their adolescent to diet), as did increased dieting frequency among mothers. Conclusion: The present study provides novel insights to the scant literature on WBI in youth. Findings indicate that WBI is high in both girls and boys engaged in weight loss, and is associated with maladaptive eating behaviors, higher frequency of maternal dieting, and mothers' comments about body weight. These findings have important clinical implications for youth and families engaged in weight loss treatment, and underscore the need for research to clarify adverse effects of internalization on weight-related health in youth and to better understand the role that parental weight communication may have on adolescents' internalization.

Abstract
BACKGROUND With high rates of adolescent obesity, many parents are talking to adolescents about their body weight. Parental "weight talk" is linked with adverse health behaviors in youth, but we know little about what parents say in these conversations. Using a weight loss treatment-seeking sample of adolescents, the present study assessed adolescents' emotional reactions to words their parents use to describe their weight and preferred language for these interactions. METHODS Adolescents enrolled in a national weight loss camp (N = 148) completed a questionnaire assessing their preferences for, and emotional reactions to, parental use of 18 words to describe their body weight. RESULTS Findings showed a diverse range of weight language used by parents, with many words inducing negative emotional reactions of embarrassment, shame, and sadness in adolescents. Emotional responses to weight language varied according to adolescents' gender, BMI, and experience of weight-teasing from family members. CONCLUSIONS Findings underscore the need to carefully consider language; parents should avoid making assumptions about what language to use in conversations with adolescents about their weight. Educating parents how to identify negative weight talk may help promote more supportive parental communication about weight-related health.

Abstract
BACKGROUND Adolescence is a time of rapid growth with dramatic changes in physical appearance. The body image established at this time could affect their physical and mental health throughout their entire life. However, adolescents sometimes perceive themselves as underweight or overweight irrespective of actual weight status. The purpose of the present study was to examine the extent of weight misperception for Korean adolescents, to explore socio-demographic factors associated with weight misperception, and to examine gender-specific differences in the relationships between weight misperception and health-related factors. METHODS We selected data on 3321 adolescents aged 12-18 years from the five-year Korea Health and Nutrition Examination Survey (KNHANES) datasets (2007-2011). Self-perceived weight status was compared with measured weight status by cross-tabulation. The generalized logit model was used to explore the socio-demographic factors associated with weight misperception, and separate logistic regression models were fitted to examine gender-specific differences in the relationships between weight misperception and health-related factors. RESULTS Overall, 25.8 % of boys (overestimation 17.1 %; underestimation 8.6 %) and 29.3 % of girls (overestimation 24.0 %; underestimation 5.3 %) misclassified their weight status according to the objective standards. Weight overestimation was particularly prominent among underweight girls. Weight misperception was associated with socio-demographic factors such as gender, age, BMI, place of residence, and maternal education level. Weight overestimation and underestimation in boys and weight overestimation in girls were significantly related to inappropriate weight control practice. However, weight underestimation in girls seems to be negatively linked to inappropriate weight control practice. CONCLUSIONS Based on the results of the present study, comprehensive intervention programs for adolescents and their parents could be devised to raise self-awareness of their weight status, to overcome weight misperception, and to prevent obesity and its related health risks.

Abstract
This paper explores the longitudinal effects of socioeconomic factors (i.e., parent education and family income level), foreign media, and attitude toward appearance on general and central adiposity among Chinese adolescents. A longitudinal analysis was performed using data from the China Seven Cities Study, a health promotion and smoking prevention study conducted in seven cities across Mainland China between 2002 and 2005. Participants included 5,020 middle and high school students and their parents. Explanatory variables included foreign media exposure, attitude toward appearance, parent education, and family income. Three-level, random-effect models were used to predict general adiposity (i.e., body mass index) and central adiposity (i.e., waist circumference). The Generalized Estimating Equation approach was utilized to determine the effect of explanatory variables on overweight status. Among girls, foreign media exposure was significantly negatively associated with general adiposity over time (β = − 0.06, p = 0.01 for middle school girls; β = − 0.06, p = 0.03 for high school girls). Attitude toward appearance was associated with lesser odds of being overweight, particularly among high school girls (OR = 0.86, p < 0.01). Among boys, parental education was significantly positively associated with general adiposity (β = 0.62, p < 0.01 for middle school boys; β = 0.37, p = 0.02 for high school boys) and associated with greater odds of being overweight (OR = 1.55, p < 0.01 for middle school boys; OR = 1.26, p = 0.04 for high school boys). Across all gender and grade levels, family income was significantly negatively associated with central adiposity over time. Interventions addressing Chinese adolescent overweight/obesity should consider these factors as potential focus areas. Foreign media exposure decreases BMI over time among girls. Girls placing importance on appearance have lesser odds of being overweight. Boys have greater odds of being overweight with high parent education. High family income was negatively associated with central adiposity.

Abstract
BACKGROUND Adolescent smoking has been associated with general parenting style, although potential differences between fathers and mothers were seldom investigated, especially in non-Western populations. PURPOSE The aim of this study is to investigate associations between Hong Kong adolescents' smoking and their perceptions of paternal and maternal parenting styles. METHOD In a school-based survey in 2006-2007, 33,408 adolescents (44.6 % boys; mean age 14.5 ± 1.3 years) provided information on smoking and the frequency of care and control by each parent, who was classified into one of four adolescent-reported parenting styles: authoritative (high care, high control), authoritarian (low care, high control), permissive (high care, low control), or neglectful (low care, low control). Logistic regression was used to calculate adjusted odds ratios (AORs) of current smoking (past 30 days) for parenting variables, considering potential effect modification by age, sex and parental smoking. RESULTS Maternal care and control were strongly and significantly associated with lower odds of adolescent current smoking. However, such association was weak for paternal care and observed only in girls. Conversely, paternal control was positively associated with current smoking, especially if the father smoked. The lowest AORs of current smoking were associated with authoritative mothers, permissive fathers and combinations of maternal and paternal parenting styles with an authoritative mother whether or not the father was authoritative. CONCLUSION Maternal care, control and authoritative parenting were associated with lower odds of adolescent smoking in Hong Kong. Paternal care was only weakly associated with lower odds of adolescent smoking, and paternal control was even associated with higher odds of smoking.

Abstract
OBJECTIVES To evaluate dose-response associations between misperceived weight and 32 health risk behaviors in a nationally representative sample of US adolescents. METHODS Participants included 13,864 US high school students in the 2011 Youth Risk Behavior Survey. Comparing the degree of agreement between perceived and reported actual weight, weight misperception was determined as 5 categories. Multivariable-adjusted logistic regression analyses evaluated associations of weight misperception with 32 health risk behaviors. RESULTS Both underestimated and overestimated weight were statistically significantly associated with all 32 health risk behaviors in a dose-response manner after adjustment for age, sex and race/ethnicity, where greater weight misperception was associated with higher engagement in health risk behaviors. CONCLUSIONS Understanding potential impacts of weight misperception on health risk behaviors could improve interventions that encourage healthy weight perception and attainment for adolescents.

Abstract
Objective To examine the association of constipation with exercise, non-exercise physical activity, and sedentary behaviours in Hong Kong adolescents. Methods In 2006–2007, 42 secondary schools were randomly selected to participate in the Hong Kong Student Obesity Surveillance (HKSOS) project. A total of 33692 Form 1–7 students (44.9% boys; mean age 14.8, SD 1.9 years) completed an anonymous questionnaire on lifestyle behaviours. Constipation was defined as a frequency of evacuation of less than once every two days. Exercise (moderate-to-vigorous levels) and non-exercise physical activity (NEPA) were each considered insufficient when less than 1 hour per day, and sedentary behaviours were considered excessive when over 4 hours per day. Logistic regression was used to calculate adjusted odds ratio (AOR) for constipation in relation to exercise, NEPA, and sedentary behaviours, adjusting for potential confounders. Results Constipation was identified in 15.6% (95% CI 15.2% – 16.0%) of adolescents overall, 14.0% in those with sufficient exercise and 19.6% in those without. Constipation was associated with insufficient exercise (AOR 1.26, 95% CI 1.16 – 1.36), insufficient NEPA 1.21 (1.10 – 1.33) and excessive sedentary behaviours (1.25, 1.17 – 1.34). Compared with having none of the above 3 inactive behaviours, increasing AORs of constipation were observed for having 1 (AOR 1.23), 2 (AOR 1.57) and 3 (AOR 1.88) inactive behaviours (p for trend <0.001). Conclusions Constipation was associated with insufficient physical activity and excessive sedentary behaviours among Chinese adolescents with a dose-response relation. If the association is causal, constipation could be prevented by promotion of physical activity.

Abstract
Background Few studies have examined how common physicians assess various weight-related variables and patient characteristics that predict such assessments based on adolescents’ reports. We aimed to examine how common adolescents received weight-related physical measurements and lifestyle enquiries (dietary habits and physical activity) from private practitioners and to identify factors associated with these assessments. Methods In the Hong Kong Student Obesity Surveillance (HKSOS) project, 33692 students (44.9% boys; mean age 14.8, SD 1.9 years, age range 11–18) from 42 randomly selected schools completed an anonymous questionnaire. The students were asked “In the past 12 months, has any private practitioners (or their nurses) measured or asked about these items?” Response options included height, weight, waist circumference (WC), blood pressure (BP), BMI, diet, and physical activity. Weight status was based on self-reported weight and height. Logistic regression was used to identify student characteristics associated with each assessment. Analyses were conducted using STATA 10.0. Results Among 13283 students who had doctor consultations in the past 12 months, 37.9% received physical measurements or lifestyle enquiries, with weight (20.8%), height (16.8%) and blood pressure (11.5%) being the most common, followed by diet (8.1%), BMI (6.3%), WC and physical activity (both 4.6%). In general, adolescents who were female, older, underweight or overweight/obese, had parents with higher education level, and had actively asked private practitioners for advice about weight were more likely to receive assessments of weight-related factors. Conclusions Weight-related factors in adolescents were infrequently assessed by private practitioners in Hong Kong. Generally, unhealthy weight, higher parental education and advice-seeking by adolescents predicted these assessments.

Abstract
BACKGROUND Sleep problems may have different influences on students' academic performance. We investigated the prevalence of sleep patterns, naps, and sleep disorders, and their associations with academic performance in Hong Kong adolescents. METHODS In 2007-2008, 22,678 students aged 12-18 (41.6% boys) completed a questionnaire on sociodemographic characteristics, sleep patterns and problems, and lifestyle factors including exercise, smoking, alcohol drinking, and academic performance. RESULTS The prevalence of having >8 hours of sleep was higher on holiday nights (86.4%) than on school-day nights (27.4%). Sleeping after midnight was more common before holidays (49.3%) than before school days (19.9%). Symptoms of insomnia and obstructive sleep apnea (OSA) were reported by 21.5% and 34.4% of students. Having >2 hours of weekend sleep delay was associated with poor academic performance with an odds ratio (OR) (95% confidence interval) of 1.46 (1.29-1.65). However, having 1-2 hours and >2 hours of weekend wake-up delay were both associated with less likelihood of poor academic performance with ORs of 0.64 (0.56-0.73) and 0.69 (0.59-0.80). Other factors associated with poor academic performance included >2 hours of sleep debt, OR of 1.17 (1.03-1.33); having any insomnia symptoms in the past 30 days, OR of 1.27 (1.17-1.37); and having any OSA symptoms at least weekly, OR of 1.23 (1.14-1.32). Napping in the past 5 school days was only marginally associated with poor school performance with an OR of 1.08 (1.00-1.16). CONCLUSION Poorer academic performance was associated with sleep debt, and symptoms of insomnia and OSA. Sleep compensation but not naps may be a protective factor of poor academic performance.
