The Role of General Parenting Style in Child Diet and Obesity Risk.

PURPOSE OF REVIEW: The childhood obesity epidemic is widely considered to have reached pandemic proportions. Across the world, children with obesity are facing numerous psychological and physiological issues that follow them into adulthood, frequently leading to chronic illness and early death. In an effort to combat the compounding effects of childhood overweight, researchers are attempting to identify biological and environmental contributors to child weight. Parenting styles are one recognized influence on child diet and body mass index (BMI). This review is a comprehensive examination of the literature on the influence of parenting style on childhood diet and BMI over the past 5 years. RECENT FINDINGS: Current research continues to support the use of traditional parenting style categories (i.e., authoritative, authoritarian, permissive, uninvolved/neglectful): however, newer subcategories of Baumrind's styles and the inclusion of previously underrepresented groups (e.g., fathers, cross cultural comparison studies) are shedding more light on the nuance of parenting's relationship with child weight. Parenting styles that focus on the balance of warmth and control (e.g., authoritative) in contrast to the styles dedicated to only one of these constructs (e.g., permissive, authoritarian) seem to promote the healthiest dietary habits and may be protective of child BMI.

Facial attractiveness, weight status, and personality trait attribution: The role of attractiveness in weight stigma.

The current study examined the influence of facial attractiveness and weight status on personality trait attributions (e.g., honest, friendly) among more and less facially attractive as well as thin and overweight models. Participants viewed pictures of one of four types of models (overweight/less attractive, overweight/more attractive, thin/less attractive, thin/more attractive) and rated their attractiveness (facial, body, overall) and personality on 15 traits. Facial attractiveness and weight status additively impacted personality trait ratings. In mediation analyses, the facial attractiveness condition was no longer associated with personality traits after controlling for perceived facial attractiveness in 12 personality traits. Conversely, the thin and overweight condition was no longer associated with personality traits after controlling for perceived body attractiveness in only 2 personality traits. Post hoc moderation analysis indicated that weight status differently influenced the association between body attractiveness and personality trait attribution. Findings bear implications for attractiveness bias, weight bias, and discrimination research.

A randomized trial comparing two approaches to weight loss.

Weight loss programs evidence considerable variability in treatment outcomes, and weight regain is common, signaling the need for the refinement of effective treatments. This study compared the recently developed Transforming Your Life program to the Diabetes Prevention Program, considered the "Gold Standard" in behavioral weight loss treatment. A total of 98 participants (Transforming Your Life = 51; Diabetes Prevention Program = 47) were randomized to the two weight loss interventions. The Transforming Your Life program and Diabetes Prevention Program produced comparable weight loss and maintenance outcomes. Individuals may benefit from engagement in the Transforming Your Life program, if they are searching for a somewhat novel approach to losing weight other than that offered by the Diabetes Prevention Program.

Attitudes and Beliefs About the Acceptability and Justness of Peer Victimization of Lesbian and Gay University Students.

We evaluated the acceptability and justness of anti-lesbian and gay victimization among 473 undergraduates. Participants were assigned to one of four vignette conditions that described an individual being verbally victimized in a typical college setting. Each vignette varied by victim gender (male; female) and sexual orientation (lesbian/gay; heterosexual). Participants completed background questionnaires and a measure that assessed the acceptability of the actions described in the vignettes. Overall, victimization was rated as unacceptable regardless of the sexual orientation and gender of the victim. However, participants rated the victimization of lesbian and gay students as more harmful and unjust than victimization of heterosexual students. Although the acceptability of anti-lesbian and gay victimization was low, 3%-12% of participants rated anti-lesbian and gay victimization as slightly or completely acceptable and just. Given that victimization is associated with long-term negative outcomes, college administrators should consider interventions aimed at decreasing the acceptability of victimization among students.

Changes in weight bias and perceived employability following weight loss and gain.

BACKGROUND: The present weight stigma study examined whether attitudes toward and employability of a normal weight person can change after learning that the person had been obese. METHODS: Participants (N = 154) viewed an image of a normal weight woman and rated their impression of her. Next, participants rated their impression of her overweight image after learning how she had previously gained and subsequently lost weight. RESULTS: Participants rated the model far less favorably including perceived employability if they thought the once overweight model lost weight through surgery vs. diet and exercise. How the model initially gained the weight had little impact on participant ratings. CONCLUSIONS: Surgical weight loss had a significant impact on personality judgments. These negative views extended to hiring decisions.

Stereotypical portrayals of obesity and the expression of implicit weight bias.

The strength of implicit anti-fat attitudes may be related to visual portrayals of obesity and individuals' pre-existing explicit attitudes toward appearance and weight. Participants (N=117) completed measures of explicit weight bias, beliefs about weight controllability, orientation toward personal appearance, overweight preoccupation, and two Implicit Association Tests (IAT). One IAT measured implicit anti-fat attitudes when individuals with obesity were shown engaging in behaviors congruent with common stereotypes (e.g., eating snacks, watching television), while a second IAT measured attitudes in response to stereotypically incongruent images (e.g., preparing vegetables, exercising). Whereas implicit weight bias was evident for both IATs, the stereotype congruent IAT was significantly related to higher implicit weight bias, appearance orientation, and overweight preoccupation, and was marginally related to explicit anti-fat attitudes. The stereotypical portrayal of individuals with obesity was related to implicit anti-fat attitudes, which may have implications for the development, maintenance, and expression of stigmatizing anti-fat attitudes.

Implicit bias about weight and weight loss treatment outcomes.

OBJECTIVES: The goal of the current study was to examine the impact of a weight loss intervention on implicit bias toward weight, as well as the relationship among implicit bias, weight loss behaviors, and weight loss outcomes. Additionally, of interest was the relationship among these variables when implicit weight bias was measured with a novel assessment that portrays individuals who are thin and obese engaged in both stereotypical and nonstereotypical health-related behaviors. METHODS: Implicit weight bias (stereotype consistent and stereotype inconsistent), binge eating, self-monitoring, and body weight were assessed among weight loss participants at baseline and post-treatment (N=44) participating in two weight loss programs. RESULTS: Stereotype consistent bias significantly decreased from baseline to post-treatment. Greater baseline stereotype consistent bias was associated with lower binge eating and greater self-monitoring. Greater post-treatment stereotype consistent bias was associated with greater percent weight loss. Stereotype inconsistent bias did not change from baseline to post-treatment and was generally unrelated to outcomes. CONCLUSION: Weight loss treatment may reduce implicit bias toward overweight individuals among weight loss participants. Higher post-treatment stereotype consistent bias was associated with a higher percent weight loss, possibly suggesting that losing weight may serve to maintain implicit weight bias. Alternatively, great implicit weight bias may identify individuals motivated to make changes necessary for weight loss.

A randomized trial comparing two approaches to weight loss: differences in weight loss maintenance.

This study compared treatment outcomes for a new weight loss program that emphasized reducing unhealthy relationships with food, body image dissatisfaction, and internalized weight bias (New Perspectives) to a weight loss program that emphasizes environmental modification and habit formation and disruption (Transforming Your Life). Fifty-nine overweight and obese adults (body mass index ≥ 27 kg/m(2)) were randomly assigned to either a 12-week New Perspectives or Transforming Your Life intervention. Despite equivalent outcomes at the end of treatment, the Transforming Your Life participants were significantly more effective at maintaining their weight loss than New Perspectives participants during the 6-month no-treatment follow-up period.

Stereotypical images and implicit weight bias in overweight/obese people.

PURPOSE: In this brief report, an unanswered question in implicit weight bias research is addressed: Is weight bias stronger when obese and thin people are pictured engaging in stereotype consistent behaviors (e.g., obese-watching TV/eating junk food; thin-exercising/eating healthy) as opposed to the converse? METHODS: Implicit Associations Test (IAT) data were collected from two samples of overweight/obese adults participating in weight loss treatment. Both samples completed two IATs. In one IAT, obese and thin people were pictured engaging in stereotype consistent behaviors (e.g., obese-watching TV/eating junk food; thin-exercising/eating healthy). In the second IAT, obese and thin people were pictured engaging in stereotype inconsistent behaviors (e.g., obese-exercising/eating healthy; thin-watching TV/eating junk food). RESULTS: Implicit weight bias was evident regardless of whether participants viewed stereotype consistent or inconsistent pictures. However, implicit bias was significantly stronger for stereotype consistent compared to stereotype inconsistent images. CONCLUSION: Implicit anti-fat attitudes may be connected to the way in which people with obesity are portrayed.

Examining perceived stereotype threat among overweight/obese adults using a multi-threat framework.

OBJECTIVE: The Multi-Threat Framework accounts for potentially different forms of stereotype threat that differ in target (i.e., the individual or the group) and source (i.e., the self or others). This investigation examined how these different forms of perceived stereotype threat were related to concepts, such as group identity, stereotype endorsement, stigma consciousness, etc., among overweight and obese individuals. METHOD: 216 adults completed an online survey. Participants' mean age was 23.6 (SD 10.1; range 18-64) years and mean BMI was 31.6 (SD 7.5) kg/m². RESULTS: Participants reported a history of feeling threatened by stereotypes related to weight. When reflecting on past experiences of perceived stereotype threat, participants reported greater levels of self/own stereotype threat compared to group stereotype threat. Level of stereotype threat was related to a number of personal characteristics (i.e., sex, BMI) and individual factors (i.e., group identity, stigma consciousness, fear of fat). CONCLUSION: Individuals who are overweight report a history of being threatened by negative stereotypes. The findings support the Multi-Threat Framework for stereotype threat based on body weight. Overweight individuals' susceptibility to stereotype threat may vary systematically depending on several factors. Future research should examine weight-related stereotypes' impact on cognitive and behavioral outcomes.

Step-down approach to behavioural weight loss treatment: a pilot of a randomised clinical trial.

BACKGROUND: In a stepped-down approach, patients begin with a more intensive treatment and are stepped down to a less intensive treatment based on achieving treatment goals. This study compared a standard behavioural weight loss programme (BWLP) to a stepped-down approach to treatment. METHODS: Fifty-two overweight/obese adults (Age: M = 47 years, SD = 13.5; female = 67%) participated in an 18-week BWLP. Half of them were randomly assigned to be stepped down from weekly group meetings based on completion of weight loss goals (3%) every 6 weeks, while the other half remained in their groups regardless of weight loss. RESULTS: There was a significant difference favouring the BWLP in the proportion of participants who met or exceeded their 3% weight loss goal during the first six weeks. While not statistically significant by the end of treatment, the BWLP participants lost nearly 3% more body weight than stepped-down participants (SC = 4.9% vs. BWLP = 7.8%; p = .10). Greater self-monitoring was associated with increased likelihood of stepped-care eligibility and higher percent weight loss at the end of treatment (p < .01). CONCLUSION: There was little evidence to support the efficacy of the stepped-down approach for behavioural weight loss treatment employed in this investigation.

Food addiction in adults seeking weight loss treatment. Implications for psychosocial health and weight loss.

The present study examined food addiction symptomology and its relationship to eating pathology and psychological distress among adults seeking weight loss treatment. A primary interest was an examination of the relationship between food addiction symptoms and short-term weight loss. Adults beginning a behavioral weight loss program (N=57) were given the Yale Food Addiction Scale (YFAS) as well as measures of psychological distress, disordered eating, weight bias, and weight-focused attitudes. Weight loss was measured after 7 weeks. Severity of food addiction was related to increased depression, emotional eating, binge eating, anti-fat attitudes, internalized weight bias, body shame, and low eating self-efficacy, but not body satisfaction. Increased food addiction symptomology was also related to less weight lost at 7 weeks. Findings suggest that individuals attempting to lose weight while combating symptoms of food addiction may be especially prone to eating-related pathologies, internalized weight bias, and body shame. Importantly, findings provide evidence that food addiction may undermine efforts to lose weight. The pathology associated with addiction (e.g., tolerance, withdrawal) could make the adoption of more healthful eating habits especially difficult.

Stepped-care in obesity treatment: matching treatment intensity to participant performance.

This investigation examined the effectiveness of a self-help (SH), stepped-care (SC) weight loss program. Based on a failure to achieve pre-assigned weight loss goals, participants were eligible to be stepped-up from a SH program to two levels of treatment intensity (weight loss group [WLG]; individual counseling [IC]) beyond SH. The primary outcome was change in body weight. Fifty-three overweight/obese adults (BMI≥27 kg/m(2); mean BMI of 37.3, SD=6.6, 89% Caucasian, and 77% female) participated in an 18-week weight loss intervention. During several phases of the investigation, those stepped-up to more intensive treatment lost comparable weight to those who were not stepped-up. Nevertheless, by the end of treatment, individuals who remained in SH (M=8.6%) lost a significantly greater percentage of weight than individuals who received SH+IC (M=4.7%; p<.05) and individuals in SH+IC lost a significantly greater percentage of weight than individuals who received SH+WLG+IC (M=1.6%; p<.05). While some individuals benefited from being stepped-up to greater intensity treatment, other individuals experienced little benefit. The application of SC principles to the treatment of obesity needs further study.

The effects of reality television on weight bias: an examination of The Biggest Loser.

Weight-loss reality shows, a popular form of television programming, portray obese individuals and their struggles to lose weight. While the media is believed to reinforce obesity stereotypes and contribute to weight stigma, it is not yet known whether weight-loss reality shows have any effect on weight bias. The goal of this investigation was to examine how exposure to 40-min of The Biggest Loser impacted participants' levels of weight bias. Fifty-nine participants (majority of whom were white females) were randomly assigned to either an experimental (one episode of The Biggest Loser) or control (one episode of a nature reality show) condition. Levels of weight bias were measured by the Implicit Associations Test (IAT), the Obese Person Trait Survey (OPTS), and the Anti-fat Attitudes scale (AFA) at baseline and following the episode viewing (1 week later). Participants in The Biggest Loser condition had significantly higher levels of dislike of overweight individuals and more strongly believed that weight is controllable after the exposure. No significant condition effects were found for implicit bias or traits associated with obese persons. Exploratory analyses examining moderation of the condition effect by BMI and intention to lose weight indicated that participants who had lower BMIs and were not trying to lose weight had significantly higher levels of dislike of overweight individuals following exposure to The Biggest Loser compared to similar participants in the control condition. These results indicate that anti-fat attitudes increase after brief exposure to weight-loss reality television.

The self-protective nature of implicit identity and its relationship to weight bias and short-term weight loss.

BACKGROUND/AIMS: Research suggests that making overly positive self-evaluations is the norm rather than the exception. However, unlike other stigmatized groups, overweight individuals do not exhibit a positive in-group social identity and instead exhibit significant explicit, implicit, and internalized weight bias. Therefore, it is not known whether overweight/obese individuals will evidence self-enhancement on general traits (good, attractive), or on traits inconsistent with fat stereotypes (disciplined, active, healthy eater), on an assessment of implicit attitudes. Similarly, it is not known whether these ratings will be associated with preexisting levels of weight bias, gender, or short-term weight loss. METHODS: At baseline, 53 overweight/obese adults (BMI > 27 kg/m(2), mean BMI = 37.3 kg/m(2), SD = 6.6 kg/m(2), 89% Caucasian, and 77% female) participating in a weight loss intervention completed measures of explicit and internalized weight bias as well as implicit weight bias and identity (self-other comparisons). RESULTS: Although participants evidenced significant anti-fat attitudes, they implicitly identified themselves as significantly thinner, better, more attractive, active, disciplined, and more likely to eat healthy than 'other' people. Compared to men, women were less likely to view themselves as thin and attractive relative to others. Greater implicit anti-fat bias and implicitly seeing the self as thin relative to others was associated with less short-term weight loss. CONCLUSION: Despite evidence for explicit, implicit, and internalized weight bias, participants generally evidenced a positive implicit self-identity, including areas consistent with negative fat stereotypes.

Transforming your life: an environmental modification approach to weight loss.

This investigation compared a traditional behavioral weight loss program with a weight loss intervention emphasizing environmental modification and habit formation and disruption. Fifty-four overweight and obese adults (BMI ≥ 27 kg/m² were randomly assigned to either a 14-week LEARN or TYL intervention. Forty-two participants completed the six-month follow-up assessment. Treatment outcomes between LEARN and TYL participants were equivalent. During the six-month no-treatment follow-up period, participants evidenced a 3.3 lb (SD = 9.2) weight gain. The TYL intervention appears to represent an attractive option for individuals seeking an alternative to the traditional behavioral approach to weight loss.
