Assessing Health-Related Quality of Life among Older People in Rural Bangladesh

Instruments used to assess quality of life of older adults in African countries: a scoping review

Background

Over 60% of the population in sub-Saharan Africa, live in informal settlements (slums) with little or no resources. To be prepared to meet the needs of older people living in slums, it is necessary to know more about their quality of life (QoL). The objective of this review is to identify instruments, which can be used by researchers to assess the QoL of older adults living in African countries, especially those dwelling in slums.

Methods

A scoping review was performed using the databases Scopus, PubMed, and ISI Web of Science to retrieve studies published from January 2008 – September 2020. Studies were included if they reported generic QoL instruments, focused on adults with a mean age ≥ 50 and were conducted in African countries.

Results

In total, 18 studies were included using 7 unique instruments to measure QoL (EUROHIS-QOL-8, SWLS, WHOQOL-OLD, the WHOQOL-BREF, SF-36, SF-12 and RAND-38). All instruments could be interviewer-administered and had 5–36 items. However, little is known about their psychometric properties (validity and reliability), time-investment and cultural sensitivity of the domains included in the instruments.

Conclusions

Even though this review retrieved instruments used to assess QoL of older adults in African countries, there is a need for further research on adjustment and validation of currently existing QoL instruments. In addition, the development and validation of a new instrument which can be used in (illiterate) older populations, living in slums in Africa should be considered.

A cultural adaptation and validation of a child eating behaviour measure in a low- and middle-income country

OBJECTIVE

The Child Eating Behaviour Questionnaire (CEBQ), a widely used instrument that has been validated mostly in high-income countries, has limitations in its factorial validity when used among different cultures. This study examines whether the CEBQ instrument is culturally appropriate and valid to be used in a low- and middle-income country (LMIC) in a setting where child undernutrition remains prevalent.

DESIGN

The study employed a qualitative process to validate the content of items relative to the culture and setting, which was followed by a survey to test the psychometric properties of the instrument. Tests of factorial validity, convergent validity and reliability were performed.

SETTING

Three different socio-economic settings of Yogyakarta, Indonesia.

PARTICIPANTS

The participants of this study were mothers of children aged 25-60 months. In-depth interviews were conducted with twenty-four mothers and the questionnaire validation process involved 238 mothers in the survey.

RESULTS

A Confirmatory Factor Analysis model with eight subscales provided the best fit (root-mean-square error of approximation = 0·048 (90 % CI 0·040, 0·057); Comparative Fit Index = 0·95 and Tucker Lewis Index = 0·95) after three new items and eight items from the original CEBQ were removed. Convergent validity with child's weight was found for two subscales, slowness in eating and satiety responsiveness. Reliability measured using Cronbach's alpha provided values between 0·62 and 0·78.

CONCLUSION

The original eight-factor structure of the CEBQ showed adequate content validity and provided factorial, discriminant and convergent validity with mothers of preschool children living in a LMIC where child nutrition remains a significant public health issue.

Psychometric evaluation of a newly developed Elderly-Constipation Impact Scale

Background

Chronic constipation is a common symptom among the elderly, and it may affect their quality of life (QoL). A lack of available research focused on the elderly means that this effect is not well understood. This study aimed to develop and validate a new scale (Elderly-Constipation Impact Scale (E-CIS)) to measure the impact of chronic constipation on QoL among the elderly.

Methods

A pool of items was generated from a qualitative study, literature reviews, and expert reviews. Exploratory factor analysis (EFA) was performed on the original 40 items of the E-CIS and followed by 27 items for confirmatory factor analysis (CFA). A total of 470 elderly people with chronic constipation were involved.

Results

The mean age of the participants was 68.64 ± 6.57. Finally, only 22 items were indicated as appropriately representing the E-CIS, which were grouped into seven subscales: 'daily activities', 'treatment satisfaction', 'lack of control of bodily function', 'diet restriction', 'symptom intensity', 'anxiety' and 'preventive actions'. The scale was confirmed as valid (root mean square error of approximation (RMSEA) = 0.04, comparative fit index (CFI) = 0.961, Tucker-Lewis index (TLI) = 0.952 and chi-square/degree of freedom (chiSq/df) = 1.44) and reliable (Cronbach's alpha: 0.66-0.85, composite reliability (CR) = 0.699-0.851) to assess the impact of chronic constipation on the elderly's QoL.

Conclusions

The E-CIS is useful to measure the impact of chronic constipation on the elderly's QoL. A further test is needed to determine the validity and reliability of this scale in other elderly population.

Women's successful aging

The authors investigated women's successful aging in the context of well-being and satisfaction with life. This study was conducted with 129 women in Women's Rest Homes in the province of Adana, Turkey. It was found that satisfaction with life (SL) was significantly associated with successful aging (SAS) (β = .350; p = .005; t = 2.833), and SAS (β = .358; p = .008; t = 2.632) and SL (β = .669; p ≤ 0.001; t = 4.774) were significantly associated with women's well-being (WBI). Women in the 60-66 age range had significantly higher SAS (md = 1.30314; p = .004) and struggle against difficulties (SAD) (md = 1.35624; p = .005) than those in the 81-87 age range, and women with bachelor's degrees had significantly higher SAD (md = .73590; p = .001) than women with primary school education. Women who had high monthly incomes (md = 1.75741; p = .000) were more satisfied with life than women with moderate incomes (md = .87905; p = .000), who were in turn more satisfied with life than women with low incomes (md = -.87905; p = .000). Women with high monthly incomes (md = 1.34606; p = .005) had higher well-being than women with moderate incomes (md = .70101; p = .005), who in turn had higher well-being than women with low incomes (md = -.70101; p = .005). The validity and reliability of the SAS [χ ²(27) = 67.088, p < .01; χ ²/df = 2.033; SRMR: .090; RMSEA: .080; NNFI: .905; IFI: .932; CFI: .930; GFI: .911; AGFI: .851] were verified in this study. It was determined that satisfaction with life and well-being were crucial determinants of women's successful aging.

Validation of a measurement instrument for parental child feeding in a low and middle-income country

BACKGROUND

Parental child feeding practices (PCFP) are a key factor influencing children's dietary intake, especially in the preschool years when eating behavior is being established. Instruments to measure PCFP have been developed and validated in high-income countries with a high prevalence of childhood obesity. The aim of this study was to test the appropriateness, content, and construct validity of selected measures of PCFP in a low and middle-income country (LMIC) in which there is both undernutrition and obesity in children.

METHODS

An expert panel selected subscales and items from measures of PCFP that have been well-tested in high-income countries to measure both "coercive" and "structural" behaviors. Two sequential cross-sectional studies (Study 1, n = 154; Study 2, n = 238) were conducted in two provinces in Indonesia. Findings of the first study were used to refine subscales used in Study 2. An additional qualitative study tested content validity from the perspective of mothers (the intended respondents). Factorial validation and reliability were also tested. Convergent validity was tested with child nutritional status.

RESULTS

In Study 1, a confirmatory factor analysis (CFA) model with 11 factors provided good fit (RMSEA = 0.045; CFI = 0.95 and TLI = 0.95) after two subscales were removed. Reliability was good among seven of the subscales. Following a decision to take out an additional subscale, the instrument was tested for factorial validity (Study 2). A CFA model with 10 subscales provided good fit (RMSEA = 0.03; CFI = 0.92 and TLI = 0.90). The reliability of subscales was lower than in Study 1. Convergent validity with nutrition status was found with two subscales.

CONCLUSIONS

The two studies provide evidence of acceptable psychometric properties for 10 subscales from tested instruments to measure PCFP in Indonesia. This provides the first evidence of the validity of these measures in a LMIC setting. Some shortcomings, such in the reliability of some subscales and further tests of predictive validity, require further investigation.

Development and Validation of a Measure of Quality of Life for the Young Elderly in Sri Lanka

Sri Lanka has one of the fastest aging populations in the world. Measurement of quality of life (QoL) in the elderly needs instruments developed that encompass the sociocultural settings. An instrument was developed to measure QoL in the young elderly in Sri Lanka (QLI-YES), using accepted methods to generate and reduce items. The measure was validated using a community sample. Construct, criterion and predictive validity and reliability were tested. A first-order model of 24 items with 6 domains was found to have good fit indices (CMIN/df = 1.567, RMR = 0.05, CFI = 0.95, and RMSEA = 0.053). Both criterion and predictive validity were demonstrated. Good internal consistency reliability (Cronbach's α = 0.93) was shown. The development of the QLI-YES using a societal perspective relevant to the social and cultural beliefs has resulted in a robust and valid instrument to measure QoL for the young elderly in Sri Lanka.

Determinants of Physical Health of Older People in Iran

Background. Many of the older people are encountered with physical and mental health problems, chronic diseases, and also living conditions. We aimed to evaluate the disability scores and its associated factors among a sample of older people in Iran. Material and Methods. 330 people aged 60–70 years were interviewed about daily living activities and physical functioning using two standard questionnaires. Results. According to univariate analysis, aging 66–70 years, being employed, and receiving financial aids were associated with better ADL mean score (P < 0.05). Also, being between 66 and 70 years of age, males, being illiterate, being employed, and receiving financial aids were statistically related to higher SF-36 mean scores (P < 0.05). Multivariate analyses have shown that higher age and receiving financial aids were related to less need for help and being unemployed with salary was related to higher need for help. However, being illiterate, being employed, and receiving financial aids were significant related factors for better physical functioning. Conclusions. Physical health in old people is decreased not only by aging of people but also by other factors such as financial problems and also employment status could decrease physical health of old people regardless of aging.

Assess quality of life among Iranian married women residing in rural places

It is important how women describe their quality of life. The aim of this study was to evaluate the effects of rural residence on quality of life of the married women. The Wellness and Quality of Life Questionnaire (WHOQOL) was used to assess QOL rural residence in Iranian married women. A total of 1,140 (577 urban and 563 rural) women aged 20-45 years were selected using standard cluster sampling technique in Babol, Iran. The questionnaire with 55 items consists of five domains: physical state, mental/emotional state, stress evaluation, life enjoyment, and overall quality of life. Lower scores in three domains: physical state, mental/emotional state, and stress evaluation mean better QOL. Higher scores in life enjoyment and overall quality of life mean better QOL. Rural residences smoke more and have a lower level of education, higher level physical activity, higher level of good self reported dietary, and lower long term health problems than urban residents. After adjusting confounding variables, logistic regression indicated living in rural settings statistically decrease the probability of having worse quality of life related to physical health (OR 0.67; CI 0.50-0.91), higher life enjoyment (OR 0.44; CI 0.32-0.61), and better overall QOL (OR 0.44; CI 0.37-0.61). The results have been suggested to be useful in order to anticipate greater health care needs of the rural married women and improve their quality of life by providing more opportunities for rural women.

Exploring quality of life among the elderly in Hai Duong province, Vietnam: a rural-urban dialogue

BACKGROUND

Quality of life (QoL) is an important health index for the elderly, necessary for assessing interventions, and prioritising medical and social care needs. As the ageing population in Vietnam continues to increase, understanding important dimensions of QoL for the elderly is essential. There is a paucity of research in this area, however, and the available literature focuses on functional capacities. The purpose of this article is to explore perceptions on the dimensions of QoL among the elderly in Vietnam, to use these perceptions to broaden the concept, and to explore similarities and differences between those living in urban compared to rural areas.

METHOD

Qualitative methods included in-depth interviews (IDI) with experts in ageing and elderly persons, as well as focus group discussions (FGDs) in three communes in Hai Duong province. IDIs and FGDs were recorded and transcribed. NVivo software was used to analyse the data.

RESULTS

Thematic analysis identified physical, psychological, social, environmental, religious, and economic as important dimensions of QoL. For elderly participants in both urban and rural areas, physical health, social relations, finances and economics, the physical and social environment, and psychological health were reported as important. Rural participants also identified religious practice as an important dimension of QoL. In terms of relationships, the elderly in urban areas prioritised those with their children, while the elderly in rural areas focussed their concerns on community relationships and economic conditions.

CONCLUSION

Isolating individual factors that contribute to QoL among the elderly is difficult given the inter-relations and rich cross-linkages between themes. Elderly participants in urban and rural areas broadly shared perspectives on the themes identified, in particular social relationships, but their experiences diverged around issues surrounding finances and economics, their respective physical and social environments, and the contribution of religious practice. The study findings may help provide guidance for the development of a socially and culturally relevant instrument for measuring QoL among the elderly in Vietnam. The results will also be useful for developing policies and interventions that are responsive to the needs of the elderly, and reflect the themes perceived to be important.

Health-related quality of life in old age: a comparison between rural areas in Bangladesh and Vietnam

This study compares health-related quality of life (HRQoL) and its determinants among older people (≥60 years) in rural Bangladesh and Vietnam. Cross-sectional studies among older people were conducted in Bangladesh (n = 1031) and Vietnam (n = 870). Data on HRQoL were collected using an instrument that includes 24 items distributed into 6 dimensions. Older people in Vietnam reported more favorable HRQoL outcomes than those in Bangladesh, reporting better HRQoL on physical, psychological, social, and financial dimensions. Hierarchical linear regression analyses show that advanced age, being a woman, belonging to a poor household, and reporting poor health were significantly associated with lower HRQoL scores in both Bangladesh and Vietnam. In Bangladesh, being illiterate was additionally associated with lower HRQoL scores. The results of this explorative study underline the importance of a cross-cultural understanding of HRQoL of older people and the influence of the socioecological context.

Association of bone and joint diseases with health-related quality of life among older people: a population-based cross-sectional study in rural Bangladesh

This study examined the cross-sectional association of bone and joint diseases with health-related quality of life (HRQoL) among 850 randomly sampled people aged 60 or more years in a rural area of Bangladesh. Information about arthritis, back and joint pain was collected through self-reports and two physicians' assessments at a health centre. Health-related quality of life was measured using a multi-dimensional generic instrument designed for older people that has questions on the construct's physical, psychological, social, economic, spiritual and environmental dimensions. Bivariate analyses showed that the most negative effects of bone and joint diseases were on the physical and psychological dimensions. Hierarchical linear regression analyses revealed that joint pain, whether doctor-diagnosed or self-reported, and self-reported back pain were all associated with lower HRQoL scores and accounted for almost 20 per cent of the variation (adjusted for age, sex, education, marital status, household size, income, expenditure and occupation). The analyses further revealed that women with self-reported back pain had significantly lower psychological, environmental and overall HRQoL scores than equivalent men, while self-reported joint pain was associated with significantly lower scores only for the environmental dimension. The strong association of bone and joint diseases with HRQoL underscores the importance of regarding these illnesses as public health problems.

Health promotion behaviors and quality of life among community-dwelling elderly in Korea: A cross-sectional survey

As individuals live longer, health promotion behaviors become even more important, particularly with regard to maintaining functional independence and improving quality of life (QoL). The purpose of this study was to explore the relationship between health promotion behaviors and QoL in Korean elderly living in the community. This study was a descriptive-correlational study to explore the relationship between health promotion behaviors and QoL among the community-dwelling elderly in Korea. A convenience sample of 2000 community residents who were over 65 years old and cognitively intact were selected from 32 senior centers and 242 public health centers in Korea. A total of 1920 were included in the analyses, following the exclusion of 80 incomplete questionnaires and subject refusals. Participants who consented to participate in the study were interviewed by trained interviewers with a structured questionnaire. The results of the study showed that there were statistically significant differences in QoL of the elderly related to exercise participation, alcohol abstinence and blood pressure (BP) check-up (p<.05). Multiple regression analysis revealed that perceived health status, number of chronic illnesses, activities of daily living, BP checkup, exercise, and gender were statistically significant predictors of QoL. R(2) for this whole regression model was .412, indicating that approximately 41.2% of the variance in QoL was accounted for by the linear combination of these variables. Nurses should enhance the QoL in elderly persons by facilitating health promotion behaviors through formal nursing interventions which will maintain and increase a healthy and active life.
