Overweight and Obesity among Recipients of Antiretroviral Therapy at HIV Clinics in Gaborone, Botswana: Factors Associated with Change in Body Mass Index

Background

Factors associated with overweight/obesity among antiretroviral therapy (ART) recipients have not been sufficiently studied in Botswana.

Objectives

To: (i) estimate the prevalence and trends in overweight/obesity by duration of exposure to ART among recipients, (ii) assess changes in BMI categories among ART recipients between their first clinic visit (BMI-1) and their last clinic visit (BMI-2), (iii) identify ART regimen that predicts overweight/obesity better than the others and factors associated with BMI changes among ART recipients.

Methods

A 12-year retrospective record-based review was conducted. Potential predictors of BMI change among patients after at least three years of ART exposure were examined using a multiple logistic regression model. Adjusted odds ratios (AOR) and their 95% confidence intervals (CIs) were computed. ART regimens, duration of exposure to ART, and recipients' demographic and biomedical characteristics including the presence or absence of diabetes mellitus-related comorbidities (DRC), defined as any morbidity associated with type 2 diabetes as described in the international statistical classification of diseases and related health problems (ICD-10-CM) codebook index, were investigated as potential predictors of overweight/obesity.

Results

Twenty-nine percent of recipients were overweight, 16.6% had obesity of whom 2.4% were morbidly-obese at the last clinic visit. Overweight/obese recipients were more likely to be female, to have DRC and less likely to have CD4 count between 201 and 249 cells/mm³. Neither the first-line nor the second-, third-line ART regimens predicted overweight/obesity better than the other and neither did the duration of exposure to ART. No significant linear trends were observed in the prevalence of overweight/obesity by the duration of exposure to ART.

Conclusion

These results suggest that the ART regimens studied have a comparable effect on overweight/obesity and that the duration of exposure does not affect the outcome. This study calls for further research to elucidate the relative contribution of various factors to BMI change among recipients, including ART regimens.

Food sources of energy and nutrients among adults in the US: NHANES 2003–2006

Identification of current food sources of energy and nutrients among US adults is needed to help with public health efforts to implement feasible and appropriate dietary recommendations. To determine the food sources of energy and 26 nutrients consumed by US adults the 2003-2006 National Health and Nutrition Examination Survey (NHANES) 24-h recall (Day 1) dietary intake data from a nationally representative sample of adults 19+ years of age (y) (n = 9490) were analyzed. An updated USDA Dietary Source Nutrient Database was developed for NHANES 2003-2006 using current food composition databases. Food grouping included ingredients from disaggregated mixtures. Mean energy and nutrient intakes from food sources were sample-weighted. Percentages of total dietary intake contributed from food sources were ranked. The highest ranked sources of energy and nutrients among adults more than 19 years old were: energy - yeast bread/rolls (7.2%) and cake/cookies/quick bread/pastry/pie (7.2%); protein-poultry (14.4%) and beef (14.0%); total fat - other fats and oils (9.8%); saturated fatty acids - cheese (16.5%) and beef (9.1%); carbohydrate - soft drinks/soda (11.4%) and yeast breads/rolls (10.9%); dietary fiber - yeast breads/rolls (10.9%) and fruit (10.2%); calcium - milk (22.5%) and cheese (21.6%); vitamin D - milk (45.1%) and fish/shellfish (14.4%); and potassium - milk (9.6%) and coffee/tea/other non-alcoholic beverages (8.4%). Knowledge of primary food sources of energy and nutrients can help health professionals design effective strategies to reduce excess energy consumed by US adults and increase the nutrient adequacy of their diets.

Physicians' discussions about body weight, healthy diet, and physical activity with overweight or obese elderly patients

OBJECTIVE

To investigate the correlates of physician-patient discussions about body weight, healthy diet, and physical activity.

METHOD

Subjects were 635 adults (≥65 years; mean 72.8 years) who had an increased body mass index (BMI≥25 kg/m2) and participated in a self-administered community survey. Logistic regression analyses were performed.

RESULTS

While approximately half of study participants reported having discussed healthy diets (51%) and physical activity (52%) with their physician, only 42% of those who were overweight or obese reported being recognized as such by their physician. Being moderately or severely obese, more chronic conditions, and more frequent physician visits increased the likelihood of being recognized as overweight or obese and reporting lifestyle discussions.

DISCUSSION

The health care provider is important in recognizing older patient's weight problems and discussing practical lifestyle changes. Tools for more proactive screening and implementation of follow-up behavioral counseling can help the health care providers better address obesity prevention in clinical practice.

Effectiveness of nurse practitioner coordinated team group visits for type 2 diabetes in medically underserved Appalachia

PURPOSE

To study the effectiveness of multidisciplinary nurse practitioner coordinated team (NPCT) group visits in medically underserved Appalachia on the health, knowledge, and self-efficacy of patients with type 2 diabetes (DM). The study also identified perceived barriers to participating in the diabetes programs.

DATA SOURCES

A researcher-developed tool was used to assess demographic data, clinical data, and barriers to care. The participants completed the Diabetes Knowledge Tests and the Diabetes Empowerment Scales. Two groups were assessed. One group participated in the diabetes intervention, and the other received usual care. Both groups completed the instruments prior to the intervention and after the intervention was completed.

CONCLUSIONS

The group that participated in the intervention had better clinical outcomes (blood glucose and A1Cs), greater knowledge, and better self-efficacy following the intervention than the usual care groups. This suggests that the intervention was important in improving outcomes of patients with type 2 DM. Barriers to care included fuel, time, family, work, and transportation. Barriers need to be addressed in order to have more patients participate in such programs.

IMPLICATIONS FOR PRACTICE

NPCT group visits may represent an effective means of integrating diabetes self-management education and medical management in a family practice clinic in medically underserved areas.
