RESUMEN

BACKGROUND: This study aimed to capture public beliefs about living with obesity, examine how these beliefs have changed over time and to explore whether certain characteristics were associated with them in a nationally representative sample of adults from the Republic of Ireland (RoI) and Northern Ireland (NI). METHODS: A cross-sectional survey employed a random quota sampling approach to recruit a nationally representative sample of 1046 adults across NI and RoI. Telephone interviews captured information on demographics; health behaviours & attitudes; and beliefs about the consequences of obesity (measured using the Obesity Beliefs Scale). Univariable analyses compared beliefs about the consequences of living with obesity between participants with a self-reported healthy weight and those living with overweight or obesity, and non-responders (those for whom weight status could not be ascertained due to missing data). Multiple linear regression examined associations between obesity-related beliefs and socio-demographics, self-rated health and perceived ability to change health behaviours. Multiple linear regression also compared changes in obesity-related beliefs between 2013 and 2020 in the RoI. RESULTS: Higher endorsement of the negative outcomes of obesity was significantly associated with living with a healthy weight, higher self-rated health, dietary quality and perceived ability to improve diet and physical activity. Those who lived with overweight, with obesity and non-responders were less likely to endorse the negative consequences of obesity. Those living with obesity and non-responders were also more likely to support there is an increased cost and effort in maintaining a healthy weight. Comparison with survey data from 2013 showed that currently, there is a greater endorsement of the health benefits of maintaining a healthy weight (p < 0001), but also of the increased costs associated with it (p < 0001). CONCLUSION: Beliefs about the consequences of maintaining a healthy body weight are associated with individuals' weight, self-rated health, diet and perceived ease of adoption of dietary and exercise-related improvements. Beliefs about the health risks of obesity and perceived greater costs associated with maintaining a healthy weight appear to have strengthened over time. Present findings are pertinent to researchers and policy makers involved in the design and framing of interventions to address obesity.

RESUMEN

BACKGROUND: Front of pack labelling (FOPL) provides visible nutritional information and appears to influence knowledge and reformulation. However, a recent Cochrane review found limited and inconsistent evidence for behaviour change. The present review aimed to examine studies published subsequent the Cochrane review, focusing on prepackaged foods, examining the impact of FOPL on purchasing and consumption. METHODS: Controlled experimental/intervention and interrupted time series (ITS) studies were included, with no age/geography restrictions. Exposures were FOPL with objectively measured consumption/purchasing outcomes. Thirteen databases were searched (January 2017 to April 2019) and forward citation searching was undertaken on the included studies. Purchasing data from experimental studies were meta-analysed. Two series of meta-analyses were undertaken; combined FOPL versus no-FOPL and specific FOPL scheme versus no-FOPL. Outcomes were sugar (g 100 g-1 ), calories (kcal 100 g-1 ), saturated fat (g 100 g-1 ) and sodium (mg 100 g-1 ). RESULTS: We identified 14 studies, reporting consumption (experimental; n = 3) and purchasing (n = 8, experimental; n = 3, ITS). Meta-analysis of experimental studies showed sugar and sodium content of purchases was lower for combined FOPL versus no-FOPL (-0.40 g sugar 100 g-1 , P < 0.01; -24.482 mg sodium 100 g-1 , P = 0.012), with a trend for lower energy and saturated fat (-2.03 kcal 100 g-1 , P = 0.08; -0.154 g saturated fat 100 g-1 , P = 0.091). For specific FOPL, products purchased by 'high in' FOPL groups had lower sugar (-0.67 g sugar 100 g-1 , P ≤ 0.01), calories (-4.43 kcal 100 g-1 , P < 0.05), sodium (-33.78 mg 100 g-1 , P = 0.01) versus no-FOPL; Multiple Traffic Light had lower sodium (-34.94 mg 100 g-1 , P < 0.01) versus no-FOPL. Findings regarding consumption were limited and inconsistent. FOPL resulted in healthier purchasing in ITS studies. CONCLUSIONS: This review provides evidence from experimental and 'real-life' studies indicating that FOPL encourages healthier food purchasing. PROSPERO CRD42019135743.

RESUMEN

Limited literature exists on attitudes towards, knowledge of and where cancer survivors seek information on physical activity. This study aimed to address these gaps in the literature. Interviews were conducted with 19 UK-based adult cancer survivors. Interviews covered participants' knowledge of the relationship between physical activity and cancer, sources of information and attitudes towards physical activity following their cancer treatment. Data were analysed using Thematic Analysis. Key themes included "physical activity is good for you," "desire to be more physically active," "limited guidance on participation in physical activity," "multi-dimensional barriers and facilitators of physical activity." Participants thought physical activity was good for them, and felt they should be more physically active. Participants reported receiving little information from oncology health professionals, as well as a desire for more guidance. Tiredness/fatigue was an important reported barrier to physical activity participation, as were situational constraints. Social support and structured exercise programmes were reported to facilitate physical activity. Health professionals should be encouraged to direct patients to appropriate sources for guidelines on physical activity for cancer survivors. Multi-component interventions to increase physical activity behaviour that consider tiredness/fatigue and incorporate components of social support could be explored.

RESUMEN

BACKGROUND: Primary care is the 'first port of call' for weight control advice, creating a need for simple, effective interventions that can be delivered without specialist skills. Ten Top Tips (10TT) is a leaflet based on habit-formation theory that could fill this gap. The aim of the current study was to test the hypothesis that 10TT can achieve significantly greater weight loss over 3 months than 'usual care'. METHODS: A two-arm, individually randomised, controlled trial in primary care. Adults with obesity were identified from 14 primary care providers across England. Patients were randomised to either 10TT or 'usual care' and followed up at 3, 6, 12, 18 and 24 months. The primary outcome was weight loss at 3 months, assessed by a health professional blinded to group allocation. Difference between arms was assessed using a mixed-effect linear model taking into account the health professionals delivering 10TT, and adjusted for baseline weight. Secondary outcomes included body mass index, waist circumference, the number achieving a 5% weight reduction, clinical markers for potential comorbidities, weight loss over 24 months and basic costs. RESULTS: Five-hundred and thirty-seven participants were randomised to 10TT (n=267) or to 'usual care' (n=270). Data were available for 389 (72%) participants at 3 months and for 312 (58%) at 24 months. Participants receiving 10TT lost significantly more weight over 3 months than those receiving usual care (mean difference =-0.87kg; 95% confidence interval: -1.47 to -0.27; P=0.004). At 24 months, the 10TT group had maintained their weight loss, but the 'usual care' group had lost a similar amount. The basic cost of 10TT was low, that is, around £23 ($32) per participant. CONCLUSIONS: The 10TT leaflet delivered through primary care is effective in the short-term and a low-cost option over the longer term. It is the first habit-based intervention to be used in a health service setting and offers a low-intensity alternative to 'usual care'.

RESUMEN

BACKGROUND/OBJECTIVES: The General Nutrition Knowledge Questionnaire (GNKQ) was developed in the 1990s and has been widely used. Since then advances in understanding of associations between diet and disease have led to changes in dietary recommendations. This study reports the validity and reliability of an updated version of the GNKQ, bringing it into line with current nutritional advice. METHODS/SUBJECTS: Following a review of current recommendations, the revised version of the GNKQ (GNKQ-R) was created, consisting of 88 items and four sections. Reliability and validity of the GNKQ-R were determined in four validation studies: (1) reliability was examined using an online sample (n=266), (2) construct validity was assessed with 96 Dietetics students and 89 english students using the 'known-groups' method, (3) associations between nutrition knowledge and socio-demographic characteristics were examined using the previously described samples and (4) sensitivity to change was tested by measuring GNKQ-R scores pre- and post-exposure to online nutrition information in written (n=65) and video (n=41) formats. RESULTS: The reliability was >0.7 in all sections. Dietetics students scored significantly higher than english students. As predicted, GNKQ-R scores were significantly higher among females vs males, people with a degree vs without, and people with very good vs poor or good health status. They were lower in those older than 50 years vs younger adults. GNKQ-R scores were significantly greater after the nutrition interventions in both written and video formats. CONCLUSIONS: The GNKQ-R is a valid measure of nutrition knowledge that is consistent, reliable and sensitive to change.

RESUMEN

Given the abundance of misreporting about diet and cancer in the media and online, cancer survivors are at risk of misinformation. The aim of this study was to explore cancer survivors' beliefs about diet quality and cancer, the impact on their behaviour and sources of information. Semi-structured interviews were conducted with adult cancer survivors in the United Kingdom who had been diagnosed with any cancer in adulthood and were not currently receiving treatment (n = 19). Interviews were analysed using Thematic Analysis. Emergent themes highlighted that participants were aware of diet affecting risk for the development of cancer, but were less clear about its role in recurrence. Nonetheless, their cancer diagnosis appeared to be a prompt for dietary change; predominantly to promote general health. Changes were generally consistent with healthy eating recommendations, although dietary supplements and other non-evidence-based actions were mentioned. Participants reported that they had not generally received professional advice about diet and were keen to know more, but were often unsure about information from other sources. The views of our participants suggest cancer survivors would welcome guidance from health professionals. Advice that provides clear recommendations, and which emphasises the benefits of healthy eating for overall well-being, may be particularly well-received.

RESUMEN

PURPOSE: There is emerging evidence for the benefits of physical activity (PA) post-diagnosis for colorectal cancer (CRC) survivors. However, population studies suggest activity levels in these patients are very low. Understanding perceived barriers and benefits to activity is a crucial step in designing effective interventions. METHODS: Patients who were between 6 months and 5 years post-diagnosis with non-metastasised disease were identified from five London (UK) hospitals. Four hundred and ninety five completed a lifestyle survey that included open-ended questions on their perceived barriers (what things would stop you from doing more physical activity?) and benefits (what do you think you would gain from doing more physical activity?). Patients also recorded their activity levels using the Godin Leisure Time Exercise Questionnaire, along with sociodemographic and treatment variables. RESULTS: The most commonly reported barriers related to cancer and its treatments (e.g. fatigue). Age and mobility-related comorbidities (e.g. impaired mobility) were also frequently cited. Those who reported age and mobility as barriers, or reported any barrier, were significantly less active even after adjustment for multiple confounders. The most frequently reported benefits were physiological (e.g. improving health and fitness). Cancer-related benefits (such as prevention of recurrence) were rarely reported. Those perceiving physiological benefits or perceiving any benefits were more active in unadjusted models, but associations were not significant in adjusted models. CONCLUSIONS: We have identified important barriers and facilitators in CRC survivors that will aid in the design of theory-based PA interventions.

RESUMEN

OBJECTIVES: To examine the proportion of normal-weight adolescents who consider themselves to be too heavy (size overestimation), and the proportion of overweight or obese adolescents who consider themselves to be about the right weight or too light (size underestimation), in large population-based samples collected over 8 years in England. METHODS: Data were from the Health Survey for England between 2005 and 2012: an annual survey of households representative of the English population. We analysed data from 4979 adolescents (2668 boys, 2311 girls) aged 13 to 15 years old whose weight status was defined as normal weight or overweight/obese based on body mass index standard deviation scores (BMI-SDS) derived from objective measurements of height and weight and using International Obesity Task Force standards. Weight perception was based on the adolescent's choice from the following descriptors: 'about the right weight', 'too heavy' or 'too light'. RESULTS: The majority of normal-weight adolescents (83% of boys, 84% of girls) correctly identified themselves as 'about the right weight'. Overestimation was uncommon, with only 7% of normal-weight teens (4% of boys, 11% of girls) identifying themselves as 'too heavy'. In contrast, only 60% of overweight/obese adolescents (53% of boys, 68% of girls) correctly identified themselves as 'too heavy', whereas 39% (47% of boys, 32% of girls) underestimated, identifying themselves as 'about the right weight' or 'too light'. There were no significant changes in BMI-SDS or body size estimation over time (2005-2012). CONCLUSIONS: Overestimation of body weight among normal-weight adolescents is relatively uncommon; potentially a cause for celebration. However, almost half of boys and a third of girls with a BMI placing them in the overweight or obese BMI range perceived themselves to be about the right weight. Lack of awareness of excess weight among overweight and obese adolescents could be a cause for concern.

RESUMEN

BACKGROUND: Despite a wealth of experimental studies on weight bias, little is known about weight discrimination at the population level. This study examined the prevalence and socio-demographic correlates of perceived weight discrimination in a large population-based sample of older adults. METHODS: Data were from 5307 adults in the English Longitudinal Study of Ageing; a population-based cohort of men and women aged ⩾50 years. Weight discrimination was reported for five domains (less respect/courtesy; treated as less clever; poorer treatment in medical settings; poorer service in restaurants/stores; threatened/harassed) at wave 5 (2010-2011). Height and weight were measured at wave 4 (2008-2009). We used logistic regression to test the odds of weight discrimination in relation to weight status, age, sex, wealth, education and marital status. RESULTS: Perceived weight discrimination in any domain was reported by 4.6% of participants, ranging from 0.8% in the normal-weight participants through 0.9, 6.7, 24.2 and 35.1% in individuals who were overweight or met criteria for class I, II and III obesity. Overall, and in each situation, odds of perceived weight discrimination were higher in younger and less wealthy individuals. There was no interaction between weight status and any socio-demographic variable. Relative to normal-weight participants, odds ratios for any perceived weight discrimination were 1.13 (95% confidence interval 0.53-2.40) in those who were overweight, 8.86 (4.65-16.88) in those with class I obesity, 35.06 (18.30-67.16) in class II obese and 56.43 (27.72-114.87) in class III obese. CONCLUSIONS: Our results indicate that rates of perceived weight discrimination are comparatively low in individuals who are overweight or have class I obesity, but for those with class II/III obesity, >10% had experienced discrimination in each domain, and >20% had been treated with less respect or courtesy. These findings have implications for public policy and highlight the need for effective interventions to promote equality.

RESUMEN

BACKGROUND: Consuming a healthy diet in pregnancy has the potential to improve obstetric outcome, including minimising the risk of macrosomia. Effective promotion of dietary change depends on identifying and targeting determinants of gestational diet. The present study aimed to model psychological predictors of intentions to reduce intake of high-fat and high-sugar foods, and increase fruit and vegetable consumption, among pregnant women. METHODS: One hundred and three pregnant women completed questionnaire measures of intentions to modify the consumption of the target foods, current intake, perceived vulnerability to and severity of adverse outcomes of unhealthful consumption of these foods (i.e. 'threat'), benefits of dietary change to mother and baby, barriers to dietary changes, and social approval for dietary change ('subjective norms'). A cross-sectional design was used. Logistic regression analyses were undertaken to model dietary change intentions. RESULTS: Participants who reported excessive current intake of high-fat and high-sugar foods were more likely to intend to reduce the intake of these foods. Perceived benefits for mother and baby enhanced intentions to eat more fruit and vegetables and eat less high-fat, and marginally significantly increased high-sugar reduction intentions. There were no effects of threat, barriers or subjective norms. CONCLUSIONS: Lack of effects for barriers, threat and subjective norms may indicate that pregnant women discount barriers to health-promoting behaviour, understand the threat posed by unhealthy eating and perceive social approval from others. Dietary change interventions for pregnant women should emphasise likely positive outcomes for both mother and child.

RESUMEN

BACKGROUND/OBJECTIVES: Strategies to achieve healthier diets for children are likely to benefit from an understanding of the determinants. We examined environmental and individual predictors of children's intake of 'core' foods (fruit and vegetables) and 'non-core' foods (snacks and sweetened beverages). Predictors included parental intake, home availability, parental feeding styles (Encouragement and Monitoring) and children's food preferences. Based on research with older children, we expected intake of both food types to be associated with maternal intake, core foods to be more associated with children's preferences and non-core food intake more with the home environment. SUBJECTS/METHODS: Primary caregivers (n=434) of children (2-5 years) from preschools and Children's Centres in London, UK, completed a self-report survey in 2008. RESULTS: Multiple regression analyses indicated children's fruit intake was associated with maternal fruit intake (B=0.29; P=0.000), children's liking for fruit (B=0.81; P=0.000) and a Monitoring style of parental feeding (B=0.13; P=0.021). Children's vegetable intake was similarly associated with maternal intake (B=0.39; P=0.000), children's liking for vegetables (B=0.77; P=0.000), Encouragement (B=0.19; P=0.021) and Monitoring (B=0.11; P=0.029). Non-core snack intake was associated with maternal intake (B=0.25; P=0.029), Monitoring (B=-0.16; P=0.010), home availability (B=0.10; P=0.022) and television viewing (TV) (B=0.28; P=0.012). Non-core drink intake was associated with maternal intake (B=0.32; P=0.000) and TV (B=0.20; P=0.019). CONCLUSIONS: Results indicate commonalities and differences in the predictors of core and non-core food intake, with only maternal intake being important across all types. Effective interventions to improve young children's diets may need to call on different strategies for different foods.

RESUMEN

BACKGROUND: The best outcomes for treating childhood obesity have come from comprehensive family-based programmes. However there are questions over their generalizability. OBJECTIVE: To examine the acceptability and effectiveness of 'family-based behavioural treatment' (FBBT) for childhood obesity in an ethnically and socially diverse sample of families in a UK National Health Service (NHS) setting. METHODS: In this parallel group, randomized controlled trial, 72 obese children were randomized to FBBT or a waiting-list control. Primary outcomes were body mass index (BMI) and BMI s.d. scores (SDSs). Secondary outcomes were weight, weight SDSs, height, height SDSs, waist, waist SDSs, FM index, FFM index, blood pressure (BP) and psychosocial measures. The outcomes were assessed at baseline and after treatment, with analyses of 6-month data performed on an intent-to-treat (ITT) basis. Follow-up anthropometric data were collected at 12 months for the treatment group. RESULTS: ITT analyses included all children with baseline data (n=60). There were significant BMI SDS changes (P<0.01) for the treatment and control groups of -0.11 (0.16) and -0.10 (1.6). The treatment group showed a significant reduction in systolic BP (-0.24 (0.7), P<0.05) and improvements in quality of life and eating attitudes (P<0.05), with no significant changes for the control group. However the between-group treatment effects for BMI, body composition, BP and psychosocial outcomes were not significant. There was no overall change in BMI or BMI SDSs from 0-12 months for the treatment group. No adverse effects were reported. CONCLUSIONS: Both treatment and control groups experienced significant reductions in the level of overweight, but with no significant difference between them. There were no significant group differences for any of the secondary outcomes. This trial was registered at http://www.controlled-trials.com/ under ISRCTN 51382628.

RESUMEN

Associations between appetite and adiposity have not been examined in clinical samples of obese children. The Children's Eating Behaviour Questionnaire (CEBQ) was used to compare appetite in community (n=406) and clinical (n=66) samples. Clear graded patterns were seen for food responsiveness and emotional overeating; levels increased with increasing BMI SDS and the clinical sample scored highest. The reverse was seen for satiety responsiveness/slowness in eating. Differences were not solely explained by weight differences, suggesting that the clinical sample had more pronounced 'obesogenic' appetitive traits. This could make adherence to dietary guidance difficult.

RESUMEN

Excessive pregnancy weight gain is associated with adverse maternal and child health outcomes. Intervention developers have assumed that adopting a healthier diet and increasing physical activity in pregnancy can limit weight gain, but evaluations of such interventions have yielded mixed results. Recent reviews of this literature have not identified defining characteristics of effective interventions. We systematically reviewed 10 published controlled trials of interventions that aimed to reduce gestational weight gain through changes in diet or physical activity. Characteristics of the sample, intervention content and delivery, and methodology were categorized. Meta-analysis showed that, overall, diet and physical activity change was effective in reducing gestational weight gain, but there was considerable heterogeneity in outcomes. Our analysis points to sample characteristics and aspects of intervention design, content, delivery and evaluation which differ between studies and may explain variation in effectiveness. Failure to evaluate changes in behaviour or its psychological determinants, and under-reporting of intervention content, may obscure identification of the processes by which weight change is effected. This limits our ability to discern active intervention ingredients. We suggest that behaviour-based gestational weight gain reduction interventions be more systematically designed, evaluated and reported to build on insights from behavioural science.

RESUMEN

There is evidence that black women are more satisfied with their body size despite higher rates of overweight. One possible mechanism is differential exposure to ultrathin images. We hypothesized that models in magazines aimed at black women are not as thin as models in materials aimed at the general population. Pictures of women from magazines aimed at black women and magazines aimed at the general population were compared (N=51). Female raters (21 white, 21 black) matched pictures to one of four drawings depicting very thin to normal-weight women. The mean body size of pictures from black magazines was significantly higher than for general magazines (p<0.001, d=0.89); 85% of pictures from general magazines were in the two thinnest size categories compared with 46% of pictures from black magazines. Media aimed at black women are less likely to use extremely slim models, which could contribute to or reflect a greater range of acceptable body sizes.

RESUMEN

OBJECTIVE: To evaluate the effect of social norms on intended fruit and vegetable intake. METHODS: A two-stage design to i) compare the perceived importance of normative influences vs cost and health on dietary choices, and ii) test the prediction that providing information on social norms will increase intended fruit and vegetable consumption in an experimental study. Home-based interviews (N=1083; 46% men, 54% women) were carried out as part of the Office for National Statistics Omnibus Survey in November 2008. RESULTS: The public's perception of the importance of social norms was lower (M=2.1) than the perceived importance of cost (M=2.7) or health (M=3.4) (all p's<0.001) on a scale from 1 (not at all important) to 4 (very important). In contrast, results from the experimental study showed that intentions to eat fruit and vegetables were positively influenced by normative information (p=0.011) in men but not by health or cost information; none of the interventions affected women's intentions. CONCLUSIONS: People have little awareness of the influence of social norms but normative information can have a demonstrable impact on dietary intentions. Health promotion might profit from emphasising how many people are attempting to adopt healthy lifestyles rather than how many have poor diets.

RESUMEN

BACKGROUND: Childhood obesity has increased steadily over recent years and has coincided with a general trend towards larger portions of foods consumed both inside and outside the home. A causal link between portion size and weight gain has not been established, although there is evidence of an association between larger portions and greater energy intake. The present study aimed to investigate parent's attitudes, knowledge, practices, and concerns about appropriate portions for children. METHODS: Four focus groups with a total of 14 volunteer mothers of 8-11-year-old children taking part in a larger school-based study. Mothers were asked their views about portion sizes for their children and were asked to demonstrate typical servings that they would offer their children, by weighing five common foods provided. Conversations were tape-recorded and transcribed for thematic analysis. RESULTS: Participants were unconcerned about portion sizes and would not welcome official guidance, particularly if it involved weighing foods. Mothers fed their children the amount that they believed they would eat and felt that this varied across children and across occasions. The weighing task revealed a wide variation in portion sizes served to children, with portions of the more energy-dense foods being smaller on average than those of less energy-dense foods. CONCLUSIONS: There was little understanding of age-appropriate serving sizes amongst mothers in this study. Education campaigns should be mindful of the need to make portion information clear and simple because parents may not be prepared to weigh the food that they serve to their children.

RESUMEN

BACKGROUND: Somalis comprise one of the largest asylum seeking populations in the UK, yet very little is known about how this migration has affected traditional attitudes towards food or eating habits. The present study was commissioned to examine the health behaviours (smoking, diet and exercise) of a Somali population in London; the study focuses on the dietary beliefs and self-reported eating behaviours of these subjects. METHODS: Because of the documented difficulty of engaging black and minority ethnic groups in research, a mixed methodology was used, involving focus groups to elicit specific dietary themes and a questionnaire survey to attempt to quantify community concordance with these themes. Eight focus groups were held in London in 2006; there were two women's and six men's groups, with 62 participants in total. The questionnaire was developed following analysis of the focus group discussions and opportunistically distributed via local Somali community organisations (77 respondents). RESULTS: The typical diet of focus group participants largely consisted of rice, pasta and red meat. There was low consumption of fruit and vegetables reported among the focus group participants: of survey respondents 97% reported eating less than two pieces of fruit, and 92% less than two portions of vegetables, a day. CONCLUSIONS: Fruit and vegetable consumption was low and there was uncertainty about what constituted a healthy diet and a stated desire for education around this. Cultural factors such as the traditional Somali diet, social associations of food and lack of appropriate information are issues that need to be addressed.

RESUMEN

OBJECTIVES: To examine changes in public perceptions of overweight in Great Britain over an eight year period. DESIGN: Comparison of data on self perceived weight from population surveys in 1999 and 2007. SETTING: Household surveys of two representative samples in Great Britain. PARTICIPANTS: 853 men and 944 women in 1999, and 847 men and 989 women in 2007. MAIN OUTCOME MEASURES: Participants were asked to report their weight and height and classify their body size on a scale from "very underweight" to "obese." RESULTS: Self reported weights increased dramatically over time, but the weight at which people perceived themselves to be overweight also rose significantly. In 1999, 81% of overweight participants correctly identified themselves as overweight compared with 75% in 2007, demonstrating a decrease in sensitivity in the self diagnosis of overweight. CONCLUSIONS: Despite media and health campaigns aiming to raise awareness of healthy weight, increasing numbers of overweight people fail to recognise that their weight is a cause for concern. This makes it less likely that they will see calls for weight control as personally relevant.
