The Relationship of Weight‐Related Attitudes With Suicidal Behaviors in Korean Adolescents

The objective of this study was to assess the relationship between weight‐related attitudes and suicidal behavior after consideration of depressive mood in Korean adolescents. The study population consisted of a nationally representative sample of 74,698 adolescents (n = 39,466 boys, 35,232 girls) in middle and high school who completed the Korea Youth Risk Behavior Web‐based Survey (KYRBWS) in 2007. Logistic regression models were used to examine the relationships between measures of weight‐related and self‐reported suicidal behavior, controlling for demographics, depressive mood, stress perception, level of school achievement, and substance use. Suicide attempts were surveyed among those reported to have suicidal ideation (n = 7,579 boys, 10,204 girls). Significantly more girls than boys reported suicidal ideation (29 vs. 19%) and suicide attempts (7.7 vs. 4.5%). Factors significantly associated with suicidal ideation were overestimation of weight (vs. correct estimation) and behaviors to lose or gain weight (vs. no weight control) among boys and overestimation of weight and attempting to lose weight among girls. In contrast, the odds of suicide attempts were significantly higher among boys who tried to lose, gain, or maintain their weight (vs. no weight control) and girls who underestimated their weight (vs. correct estimation) and tried to lose weight (vs. no weight control). Boys and girls classified as overweight or at risk for overweight were significantly less likely to report suicide attempts compared to those classified as underweight. Weight‐related attitudes, such as incorrect weight perception and weight control behaviors, seem to be useful indicators for identifying Korean adolescents who are at risk for suicidal behaviors.     

Meeting Report on the Conference on Fathers’ Role in Children’s Weight‐Related Behaviors and Outcomes

On September 22, 2017, “Engaging the Forgotten Parent: Conference of Experts on Fathers’ Role in Children’s Weight‐Related Behaviours and Outcomes” brought researchers, students, health professionals, community stakeholders, and knowledge users from Canada, Australia, and the United States together to Toronto, Ontario, for a 1‐day gathering focused on furthering scientific understanding of effective strategies to recruit, engage, and retain fathers in family‐based obesity research. Furthermore this conference focused on identifying key knowledge gaps and opportunities for collaborative research to further our understanding of fathers’ roles in the development of their children’s behaviors and weight outcomes. The following four themes emerged from the conference: (1) underrepresentation of fathers in family‐based obesity research, (2) fathers’ engagement in children’s weight‐related behaviors and desire to participate in research, (3) best practices in recruiting, engaging, and retaining fathers in research, and (4) key lessons learned from fatherhood research in developmental science.     

Weight‐Related Terms Differentially Affect Self‐Efficacy and Perception of Obesity

Objective

Little work has explored the effect of weight‐related terms on treatment initiation; only one study has investigated weight‐related terms and the psychological constructs associated with treatment uptake. The present study examines the effects of four common weight‐related terms on treatment initiation and the moderating effect of weight bias internalization.

Methods

Adult participants with overweight and obesity (n = 436) were recruited online and asked to read three vignettes describing clinical encounters; the weight‐related term (i.e., “weight,” “BMI,” “obesity,” or “fat”) was varied randomly. Participants then reported self‐efficacy, cognitive and emotional illness beliefs about obesity (i.e., illness perception), and interest in a weight loss program.

Results

The term “obesity” resulted in the greatest self‐efficacy and perceived control over obesity. “Fat” resulted in the least illness coherence (i.e., understanding of obesity). Weight bias internalization did not moderate the effect of term on self‐efficacy, nor did it moderate illness perception. No differences in weight loss program enrollment were observed.

Conclusions

Use of the term “obesity” may promote patients’ perceived control and self‐efficacy. Use of “fat” should be avoided. Results suggest that, despite patient and clinician preference for euphemistic weight terms, use of clinical language such as “obesity” may perform better in provider intervention.

     

Obesity Management: Australian General Practitioners’ Attitudes and Practices

Objectives: To document general practitioners’ (GPs) attitudes and practices regarding the prevention and management of overweight and obesity. Research Methods and Procedures: A cross‐sectional survey of a randomly selected sample of 1500 Australian GPs was conducted, of which 752 questionnaires were returned. The measures included views on weight management, definitions of success, views regarding the usefulness of drugs, approaches to and strategies recommended for weight management, and problems and frustrations in managing overweight and obesity. Results: GPs view weight management as important and feel they have an important role to play. Although they consider themselves to be well prepared to treat overweight patients, they believe that they have limited efficacy in weight management and find it professionally unrewarding. GPs view the assessment of a patient's dietary and physical activity habits and the provision of dietary and physical activity advice as very important. The approaches least likely to be considered important and/or least likely to be practiced were those that would support the patient in achieving and maintaining lifestyle change. Discussion: There remains considerable opportunity to improve the practice of GPs in their management of overweight and obesity. Although education is fundamental, it is important to acknowledge the constraints of the GPs’ existing working environment.     

Predictors of Fat Stereotypes among 9‐Year‐Old Girls and Their Parents

Objective:To assess familial links in fat stereotypes and predictors of stereotypes among girls and their parents. Research Methods and Procedures:Fat stereotypes were assessed using a questionnaire developed for this study. Participants indicated the extent to which they agreed with nine statements about thin people (e.g., thin people are smart) and the same statements about fat people (e.g., fat people are smart). Predictors of fat stereotypes that were examined include weight status (BMI; girls and parents), education (parents), income (parents), self‐investment in physical appearance (parents), maladaptive eating attitudes (girls), and parenting practices and peer interactions focused on body shape and weight loss (girls). Results:Girls and parents exhibited fat stereotypes. Fathers who were more educated and had a higher family income were more likely to endorse fat stereotypes, as were mothers and fathers with a high investment in their physical appearance. Although no associations were found between girls’ and parents’ fat stereotypes, girls were more likely to endorse fat stereotypes when interactions with parents and peers focused on body shape and weight loss. Girls were also more likely to endorse fat stereotypes when they reported higher levels of maladaptive eating attitudes. No associations were found between weight status and fat stereotypes. Discussion:Although there was no association between girls’ and parents’ fat stereotypes, girls were more likely to express negative attitudes about obesity and obese persons when parenting practices and interactions with peers promoted a lean body type, suggesting that there may be an implicit link between the lean ideal and fat stereotypes.     

Weight‐Loss Practices and Asthma: Findings from the Behavioral Risk Factor Surveillance System

Objective: To describe weight‐control practices and receipt of weight‐loss advice among obese people with asthma. Research Methods and Procedures: We analyzed data from the 2000 Behavioral Risk Factor Surveillance System. Results: Among 13,953 participants with current asthma, 27.3% had a body mass index of ≥30 kg/m2. Overall, 48.1% of participants with asthma reported trying to lose weight (64.1% among overweight or obese participants and 72.9% among obese participants). Among participants with asthma who were trying to lose or maintain weight, 74.7% reported trying to reduce their energy and/or fat intake, and 57.8% reported using physical activity. Approximately 29.7% were using the recommended combination of energy and/or fat intake reduction and physical activity of ≥150 min/wk. During the 12 months before the interview, 16.2% of overweight and 44.9% of obese participants with asthma reported receiving advice to lose weight. Among obese participants receiving weight‐loss advice, 82.9% reported trying to lose weight compared to 63.8% of participants who did not receive such advice. Discussion: Health professionals can play an important role in educating their patients with asthma about the importance of weight control and assisting their overweight and obese patients in setting appropriate weight goals and helping them achieve those goals.     

The Effect of Age on Weight‐Related Quality of Life in Overweight and Obese Individuals

The objective of the current study was to investigate the association between age and weight‐related quality of life in a broad range of overweight/obese individuals. Participants included 9,991 overweight and obese adults from a cross sectional database (mean age = 44.9, mean BMI = 38.3, 75.3% women, 73% white). Participants completed the Impact of Weight on Quality of Life‐Lite (IWQOL‐Lite), a measure of weight‐related quality of life. For the total sample, weight‐related quality of life was more impaired with increasing age for physical function, sexual life, and work. However, increasing age was associated with less impairment for self‐esteem and public distress. On the sexual life domain there was an interaction between age and gender. Men showed a steady decline in sexual life with increasing age, whereas women showed reduced scores on sexual life in all age groups beyond age 18–24.9. Of note, women's scores on all IWQOL‐Lite domains were significantly lower (more impaired) than men's. Thus, there are both positive as well as negative consequences of increasing age with respect to the impact of weight on quality of life in overweight and obese persons.     

Weight‐Bearing Physical Activity among Girls and Mothers: Relationships to Girls’ Weight Status

Objective: To assess weight‐bearing physical activity (WBPA) barriers, benefits, self‐efficacy, social influence, and behaviors [WBPA and physical activity (PA)] among girls and their mothers according to girls’ weight status (nonoverweight vs. overweight). Research Methods and Procedures: Participants were 9‐ to 11‐year‐old girls (n = 295) and their mothers who participated in the baseline assessment of a nutrition and PA intervention trial. Girls’ and mothers’ WBPA attitudes and mothers’ WBPA behaviors were self‐reported on questionnaires. Girls’ WBPA and total PA behaviors were self‐reported using a structured interview (Physical Activity Checklist Interview). Stature and weight were measured by standardized anthropometrics. Overweight status was based on BMI. Results: Compared with nonoverweight girls, overweight girls were significantly more likely to report barriers to WBPA participation and perceive social influence from family and friends to do more WBPA. They were also significantly less likely to report self‐efficacy regarding WBPA and to believe that they did enough WBPA. Compared with mothers of nonoverweight girls, mothers of overweight girls were significantly more likely to report that it is difficult to persuade their daughters to do more WBPA and significantly less likely to report that WBPA was fun for their daughters. Girls’ overweight status was not associated with girls’ reports of minutes spent per week in PA or WBPA. Discussion: The present study's findings of lower WBPA self‐efficacy, lack of enjoyment of WBPA, and higher perceived social influence to do WBPA among overweight girls suggest that efforts are needed to promote physical competencies and positive perceptions of PA among overweight girls.     

Focus: Preventive Medicine: Pre-Participation Screening of Athletes: Primary Health Care Physicians’ Knowledge,Experience, and Approach in Turkey

Pre-participation screening (PPS) is crucial for assessing the competitive athletes since their risk of sudden death is higher than non-athletes. In Turkey, PPS is performed at the primary health care setting by primary care physicians (PCPs) who are family medicine specialists (FMSs) or general practitioners (GPs). Although there are national guidelines, there is no legal regulation for this process. This study aims to evaluate PCPs’ knowledge, experience, and approach about PPS. We prepared an online survey for PCPs and used non-probabilistic sampling. PPS attitudes and practices were analyzed and compared according to factors such as experience, education, and being GP or FMS. Of the 214 PCPs included in the study, 39.3% were female. The mean age was 44.9 years (SD:8.88). The average work experience was 7.9 years. Most participants were aware of their authorization to perform PPS (89.7%) and had previously prepared it (90.2%). However, 6.5% of them felt confident in performing PPS. Only 13.1% were aware of the guidelines. Almost 25% of the participants stated being informed about the subject at some part of their career, but this did not affect the confidence or referral decisions. In addition to medical history and physical examination, further testing was considered necessary by 96.3% of the participants. Significantly more tests were ordered by GPs than FMSs (p=0.026 and p=0.011, respectively). The accurate referral decision ratio was 59.3%, without difference between FMSs and GPs (p=0.216). We found that awareness of the guidelines was low among PCPs who lack confidence in PPS. These factors collectively increased the tendency for unnecessary further testing and referral. Therefore, the PPS implementation into medical school and residency curriculums and national legal regulation for the process is a necessity in Turkey.     

Loss of Total and Visceral Adipose Tissue Mass Predicts Decreases in Oxidative Stress After Weight‐loss Surgery

It is not known whether there are mechanisms linking adipose tissue mass and increased oxidative stress in obesity. This study investigated associations between decreasing general and abdominal fat depots and oxidative stress during weight loss. Subjects were severely obese women who were measured serially at baseline and at 1, 6 (n = 30), and 24 months (n = 18) after bariatric surgery. Total fat mass (FAT) and volumes of visceral (VAT) and subcutaneous abdominal adipose tissue (SAT) were related to plasma concentrations of derivatives of reactive oxidative metabolites (dROMS), a measure of lipid peroxides and oxidative stress. After intervention, BMI significantly decreased, from 47.7 ± 0.8 kg/m² to 43.3 ± 0.8 kg/m² (1 month), 35.2 ± 0.8 kg/m² (6 months), and 30.2 ± 1.2 kg/m² (24 months). Plasma dROMS also significantly deceased over time. At baseline, VAT (r = 0.46), FAT (r = 0.42), and BMI (r = 0.37) correlated with 6‐month decreases in dROMS. Similarly, at 1 month, VAT (r = 0.43) and FAT (r = 0.41) correlated with 6‐month decreases in dROMS. Multiple regression analysis showed that relationships between VAT and dROMS were significant after adjusting for FAT mass. Increased plasma dROMS at baseline were correlated with decreased concentrations of high‐density lipoprotein (HDL) at 1 and 6 months after surgery (r = ?0.38 and ?0.42). This study found longitudinal associations between general, and more specifically intra‐abdominal adiposity, and systemic lipid peroxides, suggesting that adipose tissue mass contributes to oxidative stress.     

Development and Evaluation of Patient‐Centered Software for a Weight‐Management Clinic

Objective: To describe a weight‐management clinic software system and to report on its preliminary evaluation. Research Methods and Procedures: The software system standardizes the collection of relevant patient information from an initial medical assessment, weekly clinic visits, and laboratory testing protocol of a medically supervised proprietary meal‐replacement program in a university‐based referral clinic. It then generates monthly patient feedback reports with graphs of clinical and laboratory parameters to support a patient‐centered approach to weight management. After patients and clinic physicians review the data to ensure accuracy, the database is used for subsequent patient feedback reports, reports to referring physicians, quality assurance, and research. Clinic physicians and referring physicians were asked to rate their acceptance of the system. In addition, in a retrospective analysis of data generated by the system, outcomes for patients who received system‐generated feedback (n = 620) were compared with those who participated in the program before the introduction of feedback (n = 130). Results: Clinic and referring physicians reported that they had high overall satisfaction with the software and that the system saved them time, and the latter group reported that it decreased laboratory use. Regarding patients, the feedback group had lower dropout rates in the latter half of the program, better rates of attendance, completion of laboratory tests, and weight loss after 8 weeks. Discussion: The software seems to facilitate the effectiveness of the treatment protocol for obesity and generates a high‐quality database for patient care, clinic administration, quality assurance, and research purposes.     

Obesity‐Related Knowledge,Attitudes, and Behaviors in Obese and Non‐obese Urban Philadelphia Female Adolescents

Objectives: To examine relationships between knowledge, attitudinal and behavioral factors, and obesity and to determine how these factors influence obesity status in west Philadelphia female adolescents. Research Methods and Procedures: A matched‐pairs study was conducted with 32 stature‐ and age‐matched pairs of obese (body mass index and triceps skinfold ≥95th percentile of National Health and Nutrition Examination Survey I) and non‐obese (body mass index and triceps skinfold between the 15th and 85th percentiles of National Health and Nutrition Examination Survey I) female African American adolescents (aged 11 to 15 years), selected from a school‐based study sample, based on obesity status and matching criteria. Adolescents were compared on the following measures: physical activity, inactivity, dietary intake, eating attitudes, health behavior knowledge, body image, self‐esteem, and maturation status. Differences between obese and non‐obese females were tested using paired t tests and Wilcoxon matched‐pairs signed‐rank tests. Results: Physical activity, inactivity, and perception of ideal body size emerged as the most important contributory factors to obesity status. There were no statistically significant matched‐pair differences in macronutrient and micronutrient intakes, self‐esteem, eating attitudes, health behavior knowledge, or maturation status of these adolescents. Obese adolescents had significantly lower levels of physical activity, higher inactivity, and a larger perception of ideal body size than non‐obese adolescents. Discussion: Knowledge and attitudinal factors (with the exception of perception of ideal body size) had far less association with obesity than activity‐related behavioral factors. These findings suggest that future intervention strategies should pay particular attention to physical activity, inactivity, and body image attitudes.
