Health-related quality of life and sense of coherence among people with obesity: Important factors for health management

Salutogenesis, nutritional status and eating behaviour: a systematic review

OBJECTIVE

To assess the relationship between the sense of coherence (SOC), eating behaviour and nutritional status.

DESIGN

It is a systematic review.

SETTING

The following databases were searched: MEDLINE/PubMed, Science Direct/Elsevier, LILACS/Bireme, SciELO and Google Scholar, using the indexed terms 'salutogenesis', 'sense of coherence', 'nutritional status', 'nutrition', 'eating behavior' and 'healthy eating'. The indexed terms were used in Portuguese and English according to the database searched. The data were extracted in a standardised way and the quality of the studies was assessed using the Newcastle-Ottawa Scale.

PARTICIPANTS

Observational studies were included, with no limitations on the date of publication or language.

RESULTS

After reading the titles and abstracts of 1855 articles, 107 full texts were retrieved, of which 27 were included. Of these, twenty-five were cross-sectional and two were longitudinal. The average score for Newcastle-Ottawa studies was 6 and most studies were rated as moderate and low quality. The cumulative sample size of all included studies was 28 981 adults and the elderly, aged between 18 and 81 years. The studies were carried out in fifteen different countries. Fifteen articles assessed eating behaviour/habit and twelve assessed nutritional status. Studies have shown that SOC has a positive relationship with an appropriate eating behaviour/habit. On the other hand, the relationship between SOC and nutritional status was controversial among studies. The heterogeneity of the data resulting from the use of different methods of evaluation of the outcomes of interest (nutritional status and eating behaviour) made it impossible to perform a meta-analysis.

CONCLUSION

SOC was positively associated with adequate eating behaviour. However, it was not possible to establish a relationship between SOC and nutritional status.

Gender and Emotional Representation Matter: Own Illness Beliefs and Their Relationship to Obesity

Background

Current treatments of obesity often fail to consider gender and psychological aspects, which are essential for weight loss and weight maintenance. The aim of our study was to analyze subjective illness representations (SIRs) of adults with obesity according to the Common-Sense Self-Regulation Model (CSM) by assessing their associations with weight-related variables and gender.

Methods

Data was collected via online self-assessment between April 2017 and March 2018. SIRs were operationalized by the revised Illness Perception Questionnaire (IPQ-R) and illness outcomes according to the CSM were defined as BMI, eating behaviour, physical wellbeing, bodyweight satisfaction, and shape concerns. The sample consisted of 427 adults (M = 42.2 years, SD = 10.9; 82% female) with obesity (BMI: M = 42.3 kg/m², SD = 9.0). Student's t-tests and multiple hierarchical regression analyses were conducted with the control variables (age and BMI) and subjective illness representations and gender as independent variables.

Results

The explanation of outcome variances was moderate to high (21-43%) except for restraint eating behaviour (10%). Subjective illness representations showed several significant associations with weight-related variables, especially timeline and emotional representations. Female gender was significantly associated with more restraint eating behaviour [F_{(1, 400)} = 4.19, p < 0.001] and females had unfavourable values of the weight-related variables as well as a more cyclic [t₍₄₂₅₎ = 3.68, p < 0.001], and more emotional representation [t₍₁₀₀₎ = 5.17, p < 0.001] of their obesity.

Conclusion

The results of this study indicate that gender and subjective illness representations, especially the emotional representation, play an important role for weight-related variables. Therefore, the assessment of SIRs may constitute an economic tool to identify specific individual deficits of self-regulation.

Two-year weight, risk and health factor outcomes of a weight-reduction intervention programme: Primary prevention for overweight in a multicentre primary healthcare setting

Objective: To study the long-term effects of weight reduction, quality of life and sense of coherence in a primary health care (PHC)-based programme with two different intensities.Design: Prospective two-armed randomised intervention.Setting: Three PHC centres in south west of Sweden.Subjects: In total, 289 women and men aged 40-65 years with a BMI of 28-35 were recruited for a two-year weight-reduction programme. Participants were randomized to high-intensity or low-intensity groups. Blood samples, physical measurements and questionnaires were analysed. Participants received cookbooks and dietary lectures. The high-intensity group also received Motivational interviewing (MI), dietary advice on prescription (DAP- advice), a grocery store lecture, a website and weekly e-mails.Main outcome measures: Weight, quality of life, risks and health factors.Results: In total, 182 (64%) participants completed the 2-year follow-up. The total sample reduced their weight by 1 kg (p = 0.006). No significant differences regarding weight were found between the groups. Anxiety/depression decreased in EQ5-D (p = 0.021), EQ5-D VAS (p = 0.002) and SOC (p = 0.042). Between the groups, there were significant differences in EQ5-D usual activities (p = 0.004), anxiety/depression (p = 0.013), pain/discomfort (p = 0.041), fruit and vegetables (p = 0.005), HLV anxiety (p = 0.005), and visits to nurses (p = 0.012).Conclusion: The total population lost weight, and the high-intensity and low-intensity programmes did not result in significant differences in terms of weight. The high-intensity programme reported health benefits linked to lower levels of anxiety and depression, increased activity and intake of greens and reduced visits to physicians and nurses.Key pointsBoth groups had a consisting weight- reduction after two years.High intensity did not lead to a significant difference in weight reduction between the groups.The high-intensity group reported more health effects, such as better quality of life, reduced anxiety, and increased greenery intake. It is unknown how much support patients in a weight- reduction programme in PHC require to succeed with weight loss and a healthy lifestyle.

Identifying variables in relation to health-related quality of life among married women of reproductive age in Sivas Turkey

A cross-sectional study was performed to identify the factors associated with health-related quality of life (HRQoL) among 1,236 married Turkish women aged 15-49 years, in the urban area of Sivas, between January and July 2017. Multiple logistic regression analyzes showed that being unemployed [adjusted odds ratio (AOR) = 1.73, 95% confidence interval (CI) = 1.18-2.25], and having an unsatisfying sexual life (AOR = 1.54, 95% CI = 1.17-2.03), a chronic illness (AOR = 1.66, 95% CI = 1.27-2.17), more than three children (AOR = 1.38, 95% CI = 1.03-1.86), and experienced domestic violence (AOR = 2.15, 95% CI = 1.55-2.98) were associated with worse mental HRQoL. Having less than a high school education (AOR = 2.00, 95% CI = 1.33-3.02), a chronic illness (AOR = 2.49, 95% CI = 1.88-3.30), a history of abortion (AOR = 1.59, CI = 1.09-2.31), and experienced domestic violence (AOR = 1.71, 95% CI = 1.21-2.40) were associated with worse physical HRQoL. These findings suggest that health care providers or policy makers should pay special attention to unemployed women who are less educated, have more than three children and those having unsatisfied sexual lives, chronic illness, domestic violence experience and abortion history to enhance their HRQoL.

Health-related lifestyle and perceived health among people with severe mental illness: Gender differences and degree of sense of coherence

People with severe mental illness (SMI) experience an increased risk of physical ill health and premature death, which appears to be partly related to unhealthy lifestyle habits. The aim of this study was to describe the distribution of health-related lifestyle habits and perceived health among people with severe mental illness. A further aim was to explore if there were any gender differences or differences based on degree of sense of coherence. The study adopted a cross-sectional design based on data from 65 people with SMI. The results show that degree of Sense of Coherence (SOC) does have relevance for perceived health and for dimensions of Quality of Life (QOL). Furthermore, among the participants with strong SOC, there were less daily smokers and they seemed to have less sedentary leisure time than those with low SOC. Men reported more anxiety/depression than women and women ate fruit more often than men, otherwise there were no gender differences. In comparison with the general population, people with SMI show a higher Body Mass Index are more sedentary, more often daily smokers, have lower SOC and perceive a lower QOL. This emphasizes the importance of health-promotion support that focuses on lifestyle changes, and support for strengthening SOC and QOL for people with SMI.

Sex differences in relation patterns between health-related quality of life of older adults and its correlates: a population-based cross-sectional study in Madeira, Portugal

A population-based cross-sectional study aimed to examine sex differences in health-related quality of life (HRQoL) of older adults, and investigate whether the relation patterns between HRQoL and its correlates differed between sexes. A stratified proportional and representative sample included 802 volunteers, aged 60–79. HRQoL (36-item Short Form Health Survey), functional fitness (Senior Fitness Test), physical activity (PA) (Baecke questionnaire), demographic information and health features (questionnaires) were assessed. Men showed significantly higher HRQoL (P<0.001). Body mass index, body strength, aerobic endurance, PA, depressive symptoms, falls, and living alone were significantly related to HRQoL. With sex as moderator, these relations were not significant, except for PA (β=0.12, P=0.004). A significant interaction of sex with PA on HRQoL (β=0.08, P=0.037) was found, indicating that this relation was higher in men. A similar relation pattern was found for HRQoL physical component. HRQoL and its correlates differed between sexes, demanding a sex specific approach to promote HRQoL.
