Misperception of Healthy Weight: Associations Among Weight, Body Size Satisfaction and Body Appreciation in Older Adults

Desired weight loss and its association with health, health behaviors and perceptions in an adult population with weight excess: One-year follow-up

Background

Metabolic syndrome (MetS) worsens quality of life and increases mortality. Dissatisfaction with weight in patients with MetS may modify the effect of lifestyle interventions to achieve changes in health-related behaviors.

Objective

To assess 1-year changes in cardiovascular risk scores, self-perceived general health and health-related behaviors according to observed changes in desired weight loss during the first year of intervention in a large cardiovascular prevention trial.

Design

Prospective analysis of the PREDIMED-PLUS trial, including 5,499 adults (55–75 years old) with overweight or obesity at baseline.

Methods

The desired weight loss was the difference between ideal and measured weight. Tertiles of change in desired weight loss (1 year vs. baseline) were defined by the following cut-off points: ≥0.0 kg (T1, n = 1,638); 0.0 to −4.0 kg (T2, n = 1,903); ≤−4.0 kg (T3, n = 1,958). A food frequency questionnaire assessed diet and the Minnesota-REGICOR questionnaire assessed physical activity. The Framingham equation assessed cardiovascular risks. The changes in the severity of MetS were also assessed. The Beck Depression Inventory assessed depressive symptoms and the SF-36 assessed health-related quality of life. Data were analyzed using general linear models.

Results

BMI decreased at T2 and T3 (T1: 0.3, T2: −0.7, T3: −1.9). The most significant improvement in diet quality was observed at T3. Cardiovascular risk decreased at T2 and T3. Mean reductions in MetS severity score were: −0.02 at T1, −0.39 at T2 and −0.78 at T3. The perception of physical health increases in successive tertiles.

Conclusions

In older adults with MetS, more ambitious desired weight loss goals were associated with improvements in diet, cardiovascular health and perceived physical health during the first year of a healthy lifestyle intervention programme. Weight dissatisfaction needs to be considered by health professionals.

Modeling the associations between internal body orientation, body appreciation, and intuitive eating among early-adult and middle-adult men and women: A multigroup structural invariance analysis

This cross-sectional study investigated the associations among internal body orientation, body appreciation, intuitive eating, age, and BMI in men and women between 30 and 70 years old as delineated in the acceptance model of intuitive eating. Self-report measures were administered to a final sample of 522 individuals consisting of early-adult men (ages 30-44; n = 153), middle-adult men (ages 45-70; n = 108), early-adult women (ages 30-44; n = 135), and middle-adult women (ages 45-70; n = 126). Overall mean age was 45.03 (SD = 10.95). Structural equation modeling evidenced that, for both age groups of men and women, internal body orientation was positively associated with body appreciation and body appreciation was positively associated with intuitive eating. Internal body orientation was positively associated with intuitive eating in each group, except early-adult women. The associations among age and BMI with the aforementioned variables were inconsistent. Although evidencing measurement non-invariance among a number of parameters, multigroup structural invariance analyses showed that the associations among internal body orientation, body appreciation, intuitive eating, age, and BMI were invariant across each gender and age. These results further confirm components of the acceptance model of intuitive eating among men and women in early-adulthood and middle-adulthood.

Nutritional Status of Non-Institutionalized Adults Aged over 65. Study of Weight and Health in Older Adults (PYSMA)

BACKGROUND

A significant increase in the prevalence of malnourishment, obesity, and sarcopenic obesity has been observed in developed countries over the last few decades. In Spain, this especially happens in populations over 65 who are not institutionalized. Differences in lifestyle, medication, and economic capacity partially explain this increase.

OBJECTIVE

To study the nutritional status of a population of 65 year-olds and subjects who are not institutionalized, in the Cádiz region (Spain).

METHODS

Observational, transversal study carried out on 2621 subjects who are 65 years old and over, with a direct weight and height measurement, in 150 pharmacy offices from 44 locations. A mobile application was designed for homogeneous data collection in all the pharmacy offices. The data required from all subjects was gender, age, postal code, social security contribution regime, if the patient lives alone, type of food consumed as the main meals, level of physical activity, polypharmacy, weight, and height.

RESULTS

The prevalence of overweight and obesity amounts to 82.2% of the population (43.2% overweight and 39% obese). We found an inverse relationship between the prevalence of overweight and obesity with carrying out physical activity and having full dinners.

CONCLUSION

We identify the need to reinforce the messages to the elderly aimed at maintaining adequate physical activity and assessing the quality and quantity of dinners, as well as reducing, as much as possible, the treatments that may lead to weight gain.
