To evaluate perceived risk, control, worry, and severity about diabetes, coronary heart disease (CHD) and stroke among individuals at increased familial risk of diabetes.
Data analyses were based on the Family Healthware™ Impact Trial. Baseline health beliefs were compared across three groups: (1) no family history of diabetes, CHD or stroke (n=836), (2) family history of diabetes alone (n=267), and (3) family history of diabetes and CHD and/or stroke (n=978).
After adjusting for age, gender, race, education and BMI, scores for perceived risk for diabetes (p<0.0001), CHD (p<0.0001) and stroke (p<0.0001) were lowest in Group 1 and highest in Group 3. Similar results were observed about worry for diabetes (p<0.0001), CHD (p<0.0001) and stroke (p<0.0001). Perceptions of control or severity for diabetes, CHD or stroke did not vary across the three groups.
Among individuals at increased familial risk for diabetes, having family members affected with CHD and/or stroke significantly influenced perceived risk and worry. Tailored lifestyle interventions for this group that assess health beliefs and emphasize approaches for preventing diabetes, as well as its vascular complications, may be an effective strategy for reducing the global burden of these serious but related chronic disorders.

- "Harwell et al. (2001) found that rural survey participants who were obese and had a family history of diabetes were more likely to consider themselves at risk for diabetes . Dorman et al. (2012) found that those with increased familial risk for diabetes, CHD and stroke had high levels of perceived risk and worry about diabetes . In contrast, Adriannse et al (2003) found that participants in a diabetes screening program with diabetes risk factors such as having a family history, obesity and hypertension, did not perceive themselves to be at increased risk for the disease .

ABSTRACT: Weight misperception may have an impact on perceived risk and susceptibility for chronic diseases. Little has been reported on the long term effects of this misperception in chronic disease interventions, particularly in field of diabetes prevention. The aim of this study was to investigate the relationship between weight misperception and weight loss during a diabetes prevention project conducted in south-east Australia with individuals at moderate to high risk of developing diabetes.
A total of n=251 at risk individuals provided self-reported weight during recruitment from 2004-2006. Objectively measured weight was assessed at baseline (0-21 days after recruitment), and subsequently at three months and 12 months after the intervention. Differences between self-reported and actual weight status are presented as percentages. Linear regression was used to investigate the relationship between weight misperception and weight loss, adjusting for baseline weight and BMI.
Those who had high levels of under-reporting at baseline had greater weight loss at three and 12 months compared with those who under-reported to some degree, and those over-reporting their weight. A significant association was found between weight misperception and weight loss at the three and the 12 month time points. Baseline weight was not associated with weight loss.
Weight misperception should be acknowledged as a factor to be addressed when screening and identifying individuals at risk for diabetes. Screening and giving feedback is important in terms of awareness of participants' actual weight status and may have an effect on program outcomes.

ABSTRACT: A negative diabetes screening test may unintentionally provide reassurance, resulting in reduced incentive to follow a healthy lifestyle.
The purpose of this study is to assess negative test result effects on lifestyle and risk perception at 4 years follow-up.
Risk perception and changes in smoking, physical activity, body mass index (BMI), and waist circumference were compared between 706 high-risk participants with a negative test result and 706 high-risk participants not offered screening (controls) in a randomized controlled trial of diabetes screening.
Negative-screened individuals experienced a small but significant increase in BMI and waist circumference, but there was no significant difference with controls. The negative-screened group had significantly higher perception of risk of developing diabetes (p = 0.009) than controls, but no differences were observed in perceived personal control, worry, and optimistic bias.
Screening negative for diabetes did not lead to overt long-term changes in lifestyle, despite a high perception of risk of developing diabetes. (ISRCTN75983009.).
