Differences in weight gain in hypertensive and diabetic elderly patients primary care study

Change in Body Weight from Age 20 Years Is a Powerful Determinant of the Metabolic Syndrome

BACKGROUND

Higher body weight is a well-known determinant of the metabolic syndrome (MetS) and its components. It is however less well studied how the change in weight from age 20 years to middle age or old age affects MetS development.

METHODS

In the community-based EpiHealth (n = 19,000, age range 45 to 75 years, 56% females) and PIVUS (n = 1000, all aged 70 years, 50% females) studies, the participants were asked about their body weight at age 20 years. Data were collected to determine MetS prevalence (NCEP ATP III criteria).

RESULTS

In EpiHealth, the probability of having MetS increased fairly linearly with increasing weight from age 20 in the obese [odds ratios (OR) 1.04 per kg change in weight, 95% confidence interval (CI) 1.03-1.05, P < 0.0001], as well as in the overweight (OR 1.15, 95% CI 1.14-1.17, P < 0.0001) and normal-weight (OR 1.18, 95% CI 1.14-1.21, P < 0.0001), subjects after adjustment for age, sex, body mass index (BMI) at age 20, alcohol intake, smoking, education, and exercise habits. Also in the PIVUS study, the change in weight over 50 years was related to prevalent MetS (OR 1.08 per kg change in weight, 95% CI 1.06-1.10, P < 0.0001). In both studies, self-reported BMI at age 20 was related to prevalent MetS.

CONCLUSION

Self-reported weight gain from age 20 was strongly and independently associated with prevalent MetS both in middle age or old age. Interestingly, this relationship was not restricted only to obese subjects. Our data provide additional support for the importance of maintaining a stable weight throughout life.

Primary care obesity management in Hungary: evaluation of the knowledge, practice and attitudes of family physicians

Background

Obesity, a threatening pandemic, has an important public health implication. Before proper medication is available, primary care providers will have a distinguished role in prevention and management. Their performance may be influenced by many factors but their personal motivation is still an under-researched area.

Methods

The knowledge, attitudes and practice were reviewed in this questionnaire study involving a representative sample of 10% of all Hungarian family physicians. In different settings, 521 practitioners (448 GPs and 73 residents/vocational trainees) were questioned using a validated questionnaire.

Results

The knowledge about multimorbidity, a main consequence of obesity was balanced.

Only 51% of the GPs were aware of the diagnostic threshold for obesity; awareness being higher in cities (60%) and the highest among residents (90%). They also considered obesity an illness rather than an aesthetic issue.

There were wider differences regarding attitudes and practice, influenced by the the doctors’ age, gender, known BMI, previous qualification, less by working location.

GPs with qualification in family medicine alone considered obesity management as higher professional satisfaction, compared to physicians who had previously other board qualification (77% vs 68%). They measured their patients’ waist circumference and waist/hip ratio (72% vs 62%) more frequently, provided the obese with dietary advice more often, while this service was less frequent among capital-based doctors who accepted the self-reported body weight dates by patients more commonly. Similar reduced activity and weight-measurement in outdoor clothing were more typical among older doctors.

Diagnosis based on BMI alone was the highest in cities (85%). Consultations were significantly shorter in practices with a higher number of enrolled patients and were longer by female providers who consulted longer with patients about the suspected causes of developing obesity (65% vs 44%) and offered dietary records for patients significantly more frequently (65% vs 52%). Most of the younger doctors agreed that obesity management was a primary care issue.

Doctors in the normal BMI range were unanimous that they should be a model for their patients (94% vs 81%).

Conclusion

More education of primary care physicians, available practical guidelines and higher community involvement are needed to improve the obesity management in Hungary.
