Longitudinal changes in functional capacity: effects of socio-economic position among ageing adults.

INTRODUCTION: Health and functional capacity have improved especially in Western countries over the past few decades. Nevertheless, the positive secular trend has not been able to decrease an uneven distribution of health. The main aim of this study was to follow-up changes in functional capacity among the same people in six years time and to detect whether the possible changes vary according to socio-economic position (SEP). In addition, it is of interest whether health behaviours have an effect on these possible changes. METHODS: This longitudinal follow-up study consisted of 1,898 individuals from three birth cohorts (1926-1930, 1936-40, 1946-50) who took part in clinical check-ups and answered to a survey questionnaire in 2002 and 2008. A sub-scale of physical functioning from the RAND-36 was used to measure functional capacity. Education and adequacy of income were used as indicators of socio-economic position. Repeated-measures ANOVA was used as a main method of analysis. RESULTS: Physical functioning in 2002 and 2008 was poorest among those men and women belonging to the oldest cohort. Functional capacity deteriorated in six years among men in the oldest cohort and among women in all three cohorts. Socio-economic disparities in functional capacity among ageing people existed. Especially lower adequacy of income was most consistently associated with poorer functional capacity. However, changes in functional capacity by socio-economic position remained the same or even narrowed independent of health behaviours. CONCLUSION: Socio-economic disparities in physical functioning are mainly incorporated in the level of functioning at the baseline. No widening socioeconomic disparities in functional capacity exist. Partly these disparities even seem to narrow with ageing.

Self-rated health (SRH) and socioeconomic position (SEP) among urban home-dwelling older adults.

The main purpose of this study was to examine the association of education and adequacy of income with self-rated health (SRH) among home-dwelling older people aged 75 and over living in the urban area. A cross-sectional survey from 2008 was used to study 1395 older adults aged 75 and over living in one of the central areas of the city center of Helsinki, the capital of Finland. Associations of SRH with, education and adequacy of income were tested using ordinal regression model. Those with a lower level of education had higher level of poor health. Self-assessed adequacy of income had also a strong association with SRH. For the oldest respondents this association was even stronger than the association between education and SRH. Subjective evaluation of financial situation should be used as a key indicator of socioeconomic position (SEP) in studies examining inequalities in health especially among older adults.

Register-based data indicated nonparticipation bias in a health study among aging people.

OBJECTIVES: To examine nonparticipation in a survey by linking it with register information and identify potential nonresponse bias of inequalities in health status among aging people. STUDY DESIGN AND SETTING: Cross-sectional questionnaire survey with clinical checkups carried out in 2002 among persons born in 1926-1930, 1936-1940, and 1946-1950 in Southern Finland. The sample was linked with register information from Statistics Finland and analyzed in terms of participation and health status as measured by medicine reimbursements. RESULTS: Participation in the survey was more frequent among those who were older, female, married or cohabiting, higher educated and nonurban residents, and those with higher income and moderate health. Among nonrespondents, women were less healthy than men, whereas among respondents, the results were reversed. Among nonrespondents, better income was associated with unfavorable health. Poor health was generally more common among nonrespondents than respondents in several subgroups. CONCLUSION: Differences in response rates were found in sociodemographic factors, health, and socioeconomic position. Favorable health was generally more frequent among respondents than nonrespondents. In particular, health inequalities by gender and income differed between respondents and nonrespondents. Thus, nonresponse may lead to bias in analyses of health inequalities among aging people.

The association of functional capacity with health-related behavior among urban home-dwelling older adults.

The present study was aimed to examine whether functional capacity among the urban home-dwelling older adults associates with health-related behavior. We also examined whether health-related behavior and certain diseases can be seen as mechanisms explaining socioeconomic disparities in functional capacity. A cross-sectional survey from 2008 was used to study 1395 older adults aged 75 and over living in one of the central areas of the city center of Helsinki, the capital of Finland. Associations of activities of daily living (ADL) with, smoking, food habits, physical activity, socioeconomic status and certain diseases were tested using ordinal regression model. Current smokers had slightly poorer functional ability than non-smokers among men. Those who did not use vegetables and/or fruits daily had a poorer functional capacity than daily users. Physically inactive respondents had clearly poorer functional capacity in comparison to active ones. Those with lower education had poorer functional status than higher educated irrespective of health-related behaviors and certain diseases. As health-related behaviors are modifiable, intervention programs should be targeted at all older adults with or without health problems.

Self-rated health and social capital among aging people across the urban-rural dimension.

BACKGROUND: Previous studies have found self-rated health to be associated with social capital. However, there is lack of studies examining social capital among aging people and its impact on self-rated health in the urban-rural context. PURPOSE: The purpose of this study was to investigate associations between self-rated health and indicators of social capital (trust, various social contacts, social participation, and access to help) among aging people living in urban and rural areas in Finland. METHOD: A postal survey was conducted in 2002 among men and women born in 1926-1930, 1936-1940, or 1946-1950 and dwelling in 14 municipalities in the Päijät-Häme hospital district in Finland. A total of 2,815 participants represented 66% of the original stratified (by age, gender, and municipality) sample. Logistic regression analyses were used to examine the associations. RESULTS: Active social participation and easy access to help from others were associated with good self-rated health, especially in the urban and sparsely populated rural areas. Trust was a particularly important correlate of subjective health in the urban area, though its significance diminished after adjusting to all background variables. No overall disparities in self-rated health between the areas emerged. Social participation and access to help as indicators of social capital seem to be important resources when aging men and women assess their subjective health. CONCLUSION: Increasing efforts to encourage social participation and facilitate access to help from other persons should be included among the key priorities in community health promotion.

The effect of trust and change in trust on self-rated health: a longitudinal study among aging people.

This study examined whether trust predicted subsequent self-rated health over time at 3 years follow-up among aging people, and whether changes in trust were associated with self-rated health. Longitudinal, questionnaire-based data were collected from three age cohorts (born in 1926-1930, 1936-1940, and 1946-1950) living in the Province of Päijät-Häme, southern Finland. The response rate at the baseline in 2002 was 66% (n=2815). The follow-up was carried out in 2005, with 79% of eligible individuals participating (n=2216). Logistic regression analyses were used to derive the results. High trust was a strong predictor for good self-rated health at the follow-up. Adjusting for background variables, however, attenuated the association. In addition, good self-rated health was most common among men with sustained high trust, among women the association was somewhat weaker. Among men improvement in trust was associated with good self-rated health, but this correlation weakened after multiple adjustments. Thus, longitudinally trust is an important contributor to self-rated health among aging people. Moreover, improvement of trust but also the stability of high trust especially among men indicate better self-rated health. Trust has a positive effect on health and should therefore be seen as a significant element in health promotion.

Associations of self-rated health with different forms of leisure activities among ageing people.

OBJECTIVES: This study examined associations between self-rated health and specific forms of leisure activities - i. e. singing in a choir, art painting, playing music; art exhibitions, theatre, movies, concerts; religious events; studying and self-development; voluntary work - and investigated how confounding factors contribute to these associations among ageing people in Finland. METHODS: A postal survey was conducted in 2002 among men and women born in 1926-30, 1936-40 and 1946-50. The final 2,815 participants represented 66% of the original sample drawn, stratified by age, gender, and municipality. Logistic regression analyses were used to investigate associations between specific forms of leisure activities and self-rated health. RESULTS: Going to art exhibitions, theatre, movies, and concerts among women and studying and self-development among men were significantly positively related to self-rated health, even after adjusting for socioeconomic status (SES), other sociodemographic variables, obesity, and health behaviours. Among women, active participation in religious events and voluntary work were negatively associated with self-rated health. CONCLUSIONS: The association of leisure activities and good self-rated health may differ for genders due to their nature or meaning. Partial support was found for the assumption that leisure activities go together with better self-rated health among ageing people.

Social participation, trust and self-rated health: a study among ageing people in urban, semi-urban and rural settings.

This study examined associations between self-rated health and combinations of social participation and trust among ageing people in three living areas of Finland (N=2815, 66% response rate). Social participation and trust combinations were: low social capital (low participation/low trust), traditionalism (low/high), "the miniaturisation of community" (high/low) and high social capital (high/high). The highest rate of good self-rated health was found among the high social capital group, but after adjusting for background variables, statistical significance remained only in the urban area. High social capital measured at an individual level may thus promote health among ageing people.

Self-rated health and indicators of SES among the ageing in three types of communities.

AIMS: This paper examines associations between self-rated health, three indicators of SES (self-reported education, disposable household income, adequacy of income) and three types of communities (urban, densely or sparsely populated rural areas) among ageing men and women in the Province of Päijät-Häme, Southern Finland. There is a lack of knowledge regarding the magnitude of community type when examining the relation between subjective health and SES. METHODS: Cross-sectional questionnaire data gathered in the spring of 2002 for a prospective follow-up of community interventions were used. These data, together with a number of clinical and laboratory measurements, yielded the baseline for a 10-year community intervention study. A representative stratified (age, gender, area) sample of men and women living in the province and belonging to the birth cohorts 1926-1930, 1936-1940, and 1946-1950 was obtained from the National Population Registry. The target sample was 4,272, with 2,815 persons responding (66% response rate). RESULTS: Positive associations between indicators of SES and self-rated health were observed in all three community types. After adjusting for other factors, adequacy of income showed the strongest (positive) association with self-rated health in urban areas in all age groups. A similar pattern of associations, with varying statistical significance, though, was found in the two rural areas. CONCLUSIONS: This study supports the view that while actual income is positively correlated to health, adequacy of income is an even stronger predictor of it. Thus, there was a significant link between better financial standing and good health among ageing people, especially in urban areas.

Obesity and education: recent trends and disparities among 65- to 84-year-old men and women in Finland.

OBJECTIVES: The purpose of this study was to analyze trends and disparities in obesity by education among Finnish men and women aged 65-84 years from 1993 to 2003. METHOD.: Data were derived from nationally representative monitoring surveys conducted biennially from 1993 to 2003 by the National Public Health Institute (KTL). In total, 5740 men and 5746 women were included in the study (response rate 80%). Obesity was set as body mass index (BMI) >or=30, based on self-reported measurements. Age adjusted trends were examined by education and gender. A logistic regression model was used to study educational disparities in obesity. RESULTS: Obesity trends were similar among men and women. The prevalence of obesity increased in both educational groups over the ten-year period. Throughout the period, those with lower education had higher risk of obesity, and educational disparities persisted at about the same level. CONCLUSIONS: Obesity is increasing among older people. Information on continuing socioeconomic disparities in obesity is important for those targeting health promotion activities.

Association of smoking status with obesity and diabetes among elderly people.

The present study was aimed to examine associations of current and ex-smoking status with obesity and diabetes among elderly people. Nationwide study of Finnish elderly people based on biennial surveys from 1985 to 1995, were used to study 7482 people aged 65-79 years. Smoking status included non-, ex-light, ex-heavy, current light, and current heavy smokers. Obesity was set as body mass index (BMI) > or = 30. Information of smoking, BMI, and diabetes was based on self-reports. Logistic regression was used as the main method of analyses. Compared to non-smokers (reference category), ex-heavy smokers had higher (odds ratio, 1.42; 95% confidence interval: 1.09, 1.85) and current light smokers (OR, 0.46; 95% CI: 0.31, 0.69) lower relative risk of obesity. Current light smokers had also lower and ex-heavy smokers higher rate of diabetes than non-smokers. Ex-heavy smokers had a higher risk of obesity (OR, 1.75; 95% CI: 1.30, 2.36) and diabetes (OR, 1.48; 95% CI: 1.10, 2.01) than ex-light smokers. Same pattern for current smokers was found. Heavy ex- and current elderly smokers are at risk of obesity and diabetes. Thus, heavy smokers should be emphasized in programs promoting smoking cessation.

Trends and educational disparities in functional capacity among people aged 65-84 years.

BACKGROUND: This study examined 10 year trends in functional capacity by gender, age, and education among elderly Finns aged 65-84 years, focusing on difficulties in basic activities of daily living (BADL). Educational disparities and their trends in the prevalence of these difficulties were also assessed. METHODS: Data were derived from nationally representative monitoring surveys conducted biennially from 1993 to 2003 by the National Public Health Institute (KTL). A total of 5740 men and 5746 women were included in the study (response rate 80%). Activities of daily living (ADL) measures were used to assess levels of functional capacity. Education was divided into two groups: low (0-8 years) and high (9+ years). Age-adjusted trends and logistic regression analyses were computed. RESULTS: A clear downward trend in BADL difficulties was observed in all age groups in both genders. 80-84 year olds had clearly poorer functional ability than 65-69 year olds, even when adjusted for chronic diseases. Despite the overall improvement in functional capacity in both educational groups, low educational status persistently predicted poorer functional capacity. When chronic diseases and survey period were controlled for, the educational disparities attenuated slightly but remained significant. CONCLUSIONS: The number of Finnish elderly with BADL difficulties has declined markedly over the past 10 years. However, persistent educational disparities continue to present a challenge to public health initiatives for reducing inequalities in health.

Associations of functional ability with health-related behavior and body mass index among the elderly.

The main purpose of this study was to determine whether functional ability among the elderly associates with body mass index (BMI) and health-related behavior. The secondary aim was to examine whether health behavior and BMI can be seen as mechanisms explaining sociodemographic disparities in functional ability. Cross-sectional biennial surveys from 1985 to 2001 were used to study 11,793 Finnish people aged 65-79 years. Associations of activities of daily living (ADL) with BMI, health behaviors (smoking, alcohol consumption, diet, physical activity), time period, previous occupation, marital status and certain diseases were tested using an ordinal regression model. Current and ex-smoking, heavy and non-alcohol use, unhealthy diet, physical inactivity and obesity were associated with inferior ADL. Alcohol consumption among men showed a U-shaped relation to functional ability. Most of the differences in ADL by occupation and marital status vanished after adjustment of multiple factors. The results showed clear associations of ADL with health-related behaviors and BMI when adjusted for multiple factors. The findings suggesting a U-shaped relation between ADL and alcohol consumption among men and the association between diet and ADL add to our previous knowledge of factors related to functional ability.

Smoking and alcohol consumption among the elderly: trends and associations, 1985-2001.

BACKGROUND: Despite their clear association with health, smoking and alcohol consumption among elderly people have not been extensively researched. This study examined changes in smoking and alcohol consumption and their sociodemographic patterning among the Finnish population aged 65-79 years over the period 1985-2001. METHODS: Population-based monitoring surveys conducted biennially from 1985 to 2001 were pooled into three time periods. Trends in smoking and alcohol consumption and their sociodemographic variations among 5870 men and 5923 women were calculated. Logistic regression was used as the main method of analysis. RESULTS: Smoking declined slightly among men, and consumption of higher levels of alcohol rose in both genders from the mid-1980s to the early 2000s. Smoking among women remained at a very low level throughout the study period. Smoking and higher level of alcohol consumption were more prevalent among the younger elderly and among the men than among their counterparts. Higher alcohol use was more common among retired office workers than other former employees. Smoking was clearly more prevalent among unmarried than married people. CONCLUSIONS: Declining numbers of male smokers and remarkably few female smokers, together with positive changes already noted in diet and functional ability, suggest healthier senior years ahead. On the other hand, the rising trend of alcohol use poses a challenge to future public health.

Changes and associations in healthy diet among the Finnish elderly, 1985-2001.

BACKGROUND: diet is related to health and studies of transitions in diet among elderly people are scarce. The aim of this study was to monitor any recent changes in healthy diet among the 65- to 79-year-old population of Finnish citizens. Possible disparities in 5-year age groups, occupation and marital status were examined. METHODS: biennially conducted nationwide monitoring cross-sectional surveys among Finnish elderly people were used to study 11,793 (response rate 82%) men and women from 1985-2001. Data were pooled into three time periods. Analysis of logistic regression was used to compare and test for changes in healthy diet in categories of sociodemographic factors. RESULTS: the diet of the elderly population clearly improved from the mid-1980s to the early 2000s. The change over the monitoring period was slightly steadier among women than men. The youngest respondents, especially women, retired office employees and married persons had the healthiest diet. CONCLUSIONS: continuing improvement in diet might indicate positive health outcomes in the future. Nevertheless, there are still subgroups with unhealthier diets that include persons who are also underprivileged as far as functional ability is concerned.

Functional ability in the elderly Finnish population: time period differences and associations, 1985-99.

AIMS: The aim of this study was to determine whether functional ability among 65- to 79-year-old Finnish men and women changed at population level from the 1980s to 1990s and how gender, age, previous occupation, and marital status are associated with functional ability and whether these associations have changed over time. METHODS: Biennial surveys on health behaviour among Finnish elderly people were used to study 10,309 men and women from 1985 to 1999. Age, gender, previous occupation, and marital status were the demographic variables. Logistic regression was used to determine differences. RESULTS: Functional ability deteriorated clearly with age, but was slightly better in the 1990s than 1980s. Gender differences of functional ability were small. Retired office employees had the best functional ability. Moreover, time changes of functional ability between occupational groups were a little more positive among men than among women. Functional ability of divorced and widowed elderly emerged as slightly worse than among married persons. CONCLUSIONS: Young age and non-manual occupation prior to retirement were associated with better functional ability. The overall improvement of self-reported functional ability among elderly people suggests that the onset of disabilities could be postponed, especially if health-related circumstances were more evenly distributed at the start of or even before retirement age.
