Trends in social inequality in loneliness among adolescents 1991-2014.

Loneliness and social inequality in health are important public health concerns. We examined (i) trends in loneliness among adolescents from 1991 to 2014 in Denmark and (ii) trends in social inequality in loneliness. Study population: 11-15-year olds in random samples of schools in 1991, 1994, 1998, 2006 and 2014, n = 19 096. Loneliness was measured by a single item and social background by parents' occupational social class (OSC). We calculated absolute (%) differences in loneliness between high and low OSC and relative differences by odds ratio for loneliness. Across all surveys, 6.3% reported feeling lonely. The prevalence increased from 4.4% in 1991 to 7.2% in 2014. The prevalence of loneliness in high, middle and low OSC was 5.8, 5.9 and 8.0%. The increase in loneliness was more pronounced in higher than lower OSC, resulting in a decreasing absolute social inequality in loneliness. The statistical interaction between OSC and survey year was significant, P = 0.0176, i.e. the relative social inequality in loneliness also decreased from 1991 to 2014. The prevalence of loneliness increased from 1991 to 2014. The social inequality in loneliness decreased in both absolute and relative terms because of a rising prevalence of loneliness among children from high OSC.

Prevalence of major depressive disorder and association with personal and socio-economic factors. Results for Spain of the European Health Interview Survey 2014–2015

BackgroundDepression is a prevalent and most burdensome mental disorder. The objectives of this study are: to assess the prevalence of major depressive disorder in the adult population of Spain; and to analyse its association with personal and socio-economic factors. MethodsData from the European Health Interview Survey in Spain (2014–2015) were analysed (n = 21,546). DSM-IV Major Depressive Disorder (MDD) was assessed with the PHQ-8. Personal (age, marital status, and country of birth) and socio-economic (educational level, residence area, employment status and occupational social class) factors were also measured. Prevalence by gender and by personal and socio-economic factors was estimated. Crude (OR) and adjusted (aOR) Odds Ratio and their 95% Confidence Intervals (95%CI) were calculated using logistic regression models. All analyses were stratified by gender. ResultsPrevalence of MDD was 8.0% (95%CI: 7.3–8.6) among women and 4.1% (95%CI: 3.7–4.6) among men. For both genders, MDD was more prevalent among unemployed and among those in more disadvantaged social classes. Among women only, MDD was more prevalent for those widowed or separated, those with lower educational level, those retired, pre-retired or homemakers and in older ages. Among men only, MDD was more prevalent among those that were born in Spain. LimitationsData are cross-sectional and the sensitivity and specificity of PHQ-8 are not perfect. ConclusionsPrevalence of MDD in Spain is high, especially among women, and is strongly associated with personal variables and socio-economic disadvantage. Intersectoral interventions aimed at diminishing the impact of socio-economic disadvantage may help decreasing the societal burden of depression.

Brief Report: Trends in Social Inequality in Drunkenness Among Danish Adolescents, 1991–2014

This study examined whether social inequality in frequent drunkenness among Danish adolescents changed from 1991 to 2014. We used data from the international Health Behaviour in School-aged Children (HBSC) study, which provided nationally representative samples of 15-year-olds from seven comparable cross-sectional studies in Denmark (N = 8,655). The students provided data about frequency of drunkenness and parents' occupation. In total, 38.6% reported to have been drunk at least four times, decreasing from 44.2% in 1991 to 21.2% in 2014. Most of the decrease took place in the latter part of the period. This decrease was found in all occupational social classes, but there was no change in absolute social inequality in drunkenness four or more times reported from 1991 to 2014. The sex- and yearadjusted odds ratio for frequent drunkenness was 0.80, 95% CI [0.70, 0.93] in low compared with high occupational social class. The statistical interaction between survey year and occupational social class was insignificant (p = .3601); that is, there was no change in relative social inequality in frequent drunkenness over time. Drunkenness was more prevalent among adolescents from the high occupational social class, and this social inequality did not change from 1991 to 2014.

Is subjective social status a summary of life-course socioeconomic position?

Very little is known about the association between objective indicators of socioeconomic position in childhood and adolescence and low subjective social status in adult life, after adjusting for adult socioeconomic position. We used baseline data (2008-2010) from the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil), a multicenter cohort study of 15,105 civil servants from six Brazilian states. Subjective social status was measured using the The MacArthur Scale of Subjective Social Status, which represents social hierarchy in the form of a 10-rung ladder with the top rung representing the highest subjective social status. Participants who chose the bottom four rungs in the ladder were assigned to the low subjective social status category. The following socioeconomic position indicators were investigated: childhood (maternal education), adolescence (occupational social class of the household head; participant's occupational social class of first job; nature of occupation of household head; participant's nature of occupation of first job), and adulthood (participant's occupational social class, nature of occupation and education). The associations between low subjective social status and socioeconomic position were determined using multiple logistic regression, after adjusting for sociodemographic factors and socioeconomic position indicators from other stages of life. After adjustments, low socioeconomic position in childhood, adolescence and adulthood remained significantly associated with low subjective social status in adulthood with dose-response gradients. The magnitude of these associations was stronger for intra-individual than for intergenerational socioeconomic positions. Results suggest that subjective social status in adulthood is the result of a complex developmental process of acquiring socioeconomic self-perception, which is intrinsic to subjective social status and includes current and past, individual and family household experiences.

Persistent social inequality in medicine use for headache among adolescents in Denmark 1991-2014.

Socioeconomic variation in adolescents' medicine use behaviour is an understudied issue. To examine the association between socioeconomic background and medicine use for headache among adolescents, and how this association changes over time. Data stem from the Danish part of the international Health Behaviour in School-aged Children (HBSC) study 1991-2014 with data about parents' occupational social class (OSC) and self-reported medicine use for headache, n = 26,685. This study examined absolute social inequality (percent difference between high and low OSC) and relative social inequality (odds ratio for medicine use by OSC). In total, 40.5% used medicine for headache in the past month. There was a significant increase from 32.3% in 1991 to 42.8% in 2002 (test for trend, p < 0.0001) and very little change 2002-2014. This pattern was similar in high, middle and low OSC. The prevalence of medicine use for headache in high, middle and low OSC was 36.2%, 41.5% and 44.8% (p < 0.0001). The OR (95% CI) for medicine use was 1.25 (1.18-1.324) in middle and 1.43 (1.33-1.54) in low OSC. Medicine use for headache increased 1991-2002 and remained stable 2002-2014. There was increasing medicine use for headache with decreasing OSC; this social inequality was persistent 1991-2014.

The prevalence and determinants of polypharmacy at age 69: a British birth cohort study

BackgroundTo describe the development of polypharmacy and its components in a British birth cohort in its seventh decade and to investigate socioeconomic and gender differences independent of disease burden.MethodsData from the MRC National Survey for Health and Development were analysed to determine the prevalence and composition of polypharmacy at age 69 and changes since ages 60 to 64. Multinomial regression was used to test associations between gender, education and occupational social class and total, cardiological and non-cardiological polypharmacy controlling for disease burden.ResultsAt age 69, 22.8% of individuals were taking more than 5 medications. There was an increase in the use of 5 to 8 medications (+ 2.3%) and over 9 medications (+ 0.8%) between ages 60–64 and 69. The greatest increases were found for cardiovascular (+ 13.4%) and gastrointestinal medications (+ 7.3%). Men experienced greater cardiological polypharmacy, women greater non-cardiological polypharmacy. Higher levels of education were associated with lower polypharmacy independent of disease burden, with strongest effects seen for over five cardiological medications (RRR 0.3, 95% CI 0.2–0.5 p < 0.001 for advanced secondary qualifications compared with no qualification); there was no additional effect of social class.ConclusionsPolypharmacy increased over the seventh decade. Those with lower levels of education had more polypharmacy (total, cardiological and non-cardiological), even allowing for disease burden. Further analysis of future outcomes resulting from polypharmacy should take into account educational and gender differences, in an effort to identify at-risk populations who could benefit from medication reviews.

Social inequalities in secondhand smoke exposure in children in Spain.

INTRODUCTIONChildren are particularly vulnerable to the health effects of secondhand smoke (SHS). The objectives of this study are to describe SHS exposure of children younger than 12 years in Spain and to identify potential social inequalities associated with SHS exposure.METHODSA cross-sectional study was conducted in a representative sample of the population younger than 12 years in Spain. A computer-assisted telephone interview was conducted with parents or legal guardians in 2016, to assess the children’s SHS exposure at home, in the car, at school and at the nursery gates, in public transport, and during leisure time. The socio-demographic variables included were the child’s age and sex, the highest educational attainment at home, and occupational social class. Prevalence and 95% confidence intervals were calculated for SHS exposure in each setting and for overall exposure.RESULTSIn all, 71.8% of the children were exposed to SHS: 25.8% were exposed at home, 4.6% in the car, 8.2% in public transport, 31.9% at outdoor nursery or school gates, and 48% during leisure time. The higher the educational attainment at home, the lower the exposure (38.8% for primary school or lower, 28.7% for secondary school and 20.8% university level). The more deprived the social class, the higher the exposure (21.7% class I-II, 23.4% class III-IV and 31.1% class V-VII). SHS exposure in cars and overall exposure also decreased with higher educational achievement.CONCLUSIONSIn Spain, a large proportion of children are still exposed to SHS. Furthermore, there are clear social inequalities. To reduce SHS exposure, there is an urgent need for evidence-based interventions with an equity perspective.

Socioeconomic inequalities in childhood and adolescent body-mass index, weight, and height from 1953 to 2015: an analysis of four longitudinal, observational, British birth cohort studies

SummaryBackgroundSocioeconomic inequalities in childhood body-mass index (BMI) have been documented in high-income countries; however, uncertainty exists with regard to how they have changed over time, how inequalities in the composite parts (ie, weight and height) of BMI have changed, and whether inequalities differ in magnitude across the outcome distribution. Therefore, we aimed to investigate how socioeconomic inequalities in childhood and adolescent weight, height, and BMI have changed over time in Britain.MethodsWe used data from four British longitudinal, observational, birth cohort studies: the 1946 Medical Research Council National Survey of Health and Development (1946 NSHD), 1958 National Child Development Study (1958 NCDS), 1970 British Cohort Study (1970 BCS), and 2001 Millennium Cohort Study (2001 MCS). BMI (kg/m2) was derived in each study from measured weight and height. Childhood socioeconomic position was indicated by the father's occupational social class, measured at the ages of 10–11 years. We examined associations between childhood socioeconomic position and anthropometric outcomes at age 7 years, 11 years, and 15 years to assess socioeconomic inequalities in each cohort using gender-adjusted linear regression models. We also used multilevel models to examine whether these inequalities widened or narrowed from childhood to adolescence, and quantile regression was used to examine whether the magnitude of inequalities differed across the outcome distribution.FindingsIn England, Scotland, and Wales, 5362 singleton births were enrolled in 1946, 17 202 in 1958, 17 290 in 1970, and 16 404 in 2001. Low socioeconomic position was associated with lower weight at childhood and adolescent in the earlier-born cohorts (1946–70), but with higher weight in the 2001 MCS cohort. Weight disparities became larger from childhood to adolescence in the 2001 MCS but not the earlier-born cohorts (pinteraction=0·001). Low socioeconomic position was also associated with shorter height in all cohorts, yet the absolute magnitude of this difference narrowed across generations. These disparities widened with age in the 2001 MCS (pinteraction=0·002) but not in the earlier-born cohorts. There was little inequality in childhood BMI in the 1946–70 cohorts, whereas inequalities were present in the 2001 cohort and widened from childhood to adolescence in the 1958–2001 cohorts (pinteraction<0·05 in the later three cohorts but not the 1946 NSHD). BMI and weight disparities were larger in the 2001 cohort than in the earlier-born cohorts, and systematically larger at higher quantiles—eg, in the 2001 MCS at age 11 years, a difference of 0·98 kg/m2 (95% CI 0·63–1·33) in the 50th BMI percentile and 2·54 kg/m2 (1·85–3·22) difference at the 90th BMI percentile were observed.InterpretationOver the studied period (1953–2015), socioeconomic-associated inequalities in weight reversed and those in height narrowed, whereas differences in BMI and obesity emerged and widened. These substantial changes highlight the impact of societal changes on child and adolescent growth and the insufficiency of previous policies in preventing obesity and its socioeconomic inequality. As such, new and effective policies are required to reduce BMI inequalities in childhood and adolescence.FundingUK Economic and Social Research Council, Medical Research Council, and Academy of Medical Sciences/the Wellcome Trust.

Abstract 031: Socioeconomic Trajectories Across the Life Course and Risk of All-cause and Cardiovascular Mortality: Prospective Findings From the Moli-sani Study

Introduction: A life course approach has been suggested as the most appropriated to establish the actual impact of socioeconomic status (SES) on health outcomes. Hypothesis: We assessed the hypothesis that SES trajectories from childhood to adulthood are useful to better evaluate the role of SES towards mortality risk in a large general population-based cohort. Methods: Longitudinal analysis on 22,194 subjects recruited in the general population of the Moli-sani study, Italy (2005-2010). Educational attainment (low/high) and SES in adulthood (measured by a score including occupational social class, housing and overcrowding, and dichotomized as low/high) were used to define four possible trajectories both in low and high SES in childhood (age of 8). Hazard ratios (HR) with 95% confidence intervals (95%CI) were calculated by multivariable Cox regression and competing risk models. Results: Over a median follow-up of 8.3 years (182,924 person-years), 1155 all-cause, of which 414 cardiovascular (CVD), deaths were ascertained. In the group with low SES in childhood, as opposed to those stably low (low education and low SES in adulthood), an upward in both educational attainment and material factors in adulthood was associated with lower risk of both all-cause (HR=0.64; 95%CI 0.52-0.79; Table) and CVD mortality (HR=0.62; 0.43-0.88), respectively. Subjects with high childhood SES experienced an increased risk of total and CVD death in absence of higher educational attainment despite a higher SES in adulthood (HR=1.47; 1.04-2.07 and HR=1.75;1.00-3.05, respectively) as compared to the group with both high education and high SES in adulthood. Conclusions: In conclusion, for individuals with low SES in childhood, an upward of both educational attainment and material factors over the life course is associated with lower risk of total and CVD death. In advantaged groups in childhood, lack of a higher educational attainment, rather than material factors, over the life course appears to be unfavourably associated with survival.

Persistent social inequality in low intake of vegetables among adolescents, 2002-2014.

To examine the trend in social inequality in low intake of vegetables among adolescents in Denmark from 2002 to 2014 using occupational social class (OSC) as socio-economic indicator. Repeated cross-sectional school surveys including four waves of data collection in 2002-2014. The analyses focused on absolute social inequality (difference between high and low OSC in low vegetable intake) as well as relative social inequality (OR for low vegetable intake by OSC). The nationally representative Health Behaviour in School-aged Children (HBSC) study in Denmark. The study population was 11-15-year olds (n 17 243). Low intake of vegetables was defined as less than weekly intake measured by food frequency items. OSC was measured by student reports of parents' occupation. The proportion of participants who reported eating vegetables less than once weekly was 8·9 %, with a notable decrease from 11·9 % in 2002 to 5·9 % in 2014. The OR (95 % CI) for less than weekly vegetable intake was 2·28 (1·98, 2·63) in the middle compared with high OSC and 3·12 (2·67, 3·66) in the low compared with high OSC. The absolute social inequality in low vegetable intake decreased from 2002 to 2014 but the relative social inequality remained unchanged. The study underscores that it is important to address socio-economic factors in future efforts to promote vegetable intake among adolescents. The statistical analyses of social inequality in vegetable intake demonstrate that it is important to address both absolute and relative social inequality as these two phenomena may develop differently.

Consumption of ultra-processed foods and socioeconomic position: a cross-sectional analysis of the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil).

The objective of the study was to estimate the contribution of ultra-processed foods to total caloric intake and investigate whether it differs according to socioeconomic position. We analyzed baseline data from the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil 2008-2010; N = 14.378) and data on dietary intake using a food frequency questionnaire, assigning it into three categories: unprocessed or minimally processed foods and processed culinary ingredients, processed foods, and ultra-processed foods. We measured the associations between socioeconomic position (education, per capita household income, and occupational social class) and the percentage of caloric contribution of ultra-processed foods, using generalized linear regression models adjusted for age and sex. Unprocessed or minimally processed foods and processed culinary ingredients contributed to 65.7% of the total caloric intake, followed by ultra-processed foods (22.7%). After adjustments, the percentage of caloric contribution of ultra-processed foods was 20% lower among participants with incomplete elementary school when compared to postgraduates. Compared to individuals from upper income classes, the caloric contribution of ultra-processed foods was 10%, 15% and 20% lower among the ones from the three lowest income, respectively. The caloric contribution of ultra-processed foods was also 7%, 12%, 12%, and 17% lower among participants in the lowest occupational social class compared to those from high social classes. Results suggest that the caloric contribution of ultra-processed foods is higher among individuals from high socioeconomic positions with a dose-response relationship for the associations.

Intragenerational Social Mobility and Changes in Blood Pressure: Longitudinal Analysis From the ELSA-Brasil Study.

During the past 4 decades, the highest worldwide blood pressure (BP) levels have shifted from high-income countries to low- and middle-income countries. We investigated the association of intragenerational social mobility with changes in BP and also with the incidence of hypertension over a 4-year follow-up. Data for 6,529 baseline participants from ELSA-Brasil born between 1938 and 1975 were used. Based on a social mobility matrix, occupational social mobility was defined as the change in occupational social class between participants' first occupation and current occupation (stable high; upward; downward; stable low). Incident hypertension was defined as systolic blood pressure (SBP) ≥ 140 mm Hg or diastolic blood pressure (DBP) ≥ 90 mm Hg or use of antihypertensive medication. Hypertensive participants at baseline were excluded. Mixed effects regression models were used. Compared to the stable high group, the downwardly mobile group showed a higher increase over time in both SBP (β = 1.49, 95% CI 0.60; 2.37) and DBP (β = 0.96, 95% CI 0.32; 1.59) after adjustments for background characteristics and also proximal risk factors such as health-related behaviors and body mass index as time-dependent covariates, and diabetes. In contrast, upward mobility had no influence on BP changes (β = 0.67, 95% CI -0.07; 1.41 for SBP, and β = 0.47, 95% CI -0.05; 1.00 for DBP). Social mobility was not associated with the incidence of hypertension. We showed socioeconomic inequalities in BP progression over the life course. The longitudinal changes in BP varied by social mobility groups in the context of low- and middle-income countries, where high BP has become most prevalent.

Socioeconomic position and occupational social class and their association with risky alcohol consumption among adolescents.

To compare different measures of socioeconomic position (SEP) and occupational social class (OSC) and to evaluate their association with risky alcohol consumption among adolescents attending the last mandatory secondary school (ages 15-17years). This was a cross-sectional study. 1268 adolescents in Catalonia (Spain) participated in the study. Family affluence scale (FAS), parents' OSC, parents' level of education and monthly familiar income were used to compare socioeconomic indicators. Logistic regression analyses were conducted to evaluate socioeconomic variables and missing associated factors, and to observe the relation between each SEP variable and OSC adjusting by sociodemographic variables. Familiar income had more than 30% of missing values. OSC had the fewest missing values associated factors. Being immigrant was associated with all SEP missing values. All SEP measures were positively associated with risky alcohol consumption, yet the strength ofthese associations diminished after adjustment forsociodemographic variables. Weekly available money was the variable with the strongest association with risky alcohol consumption. OSC seems to be as good as the other indicators to assess adolescents' SEP. Adolescents withhighSEP and those belonging touppersocial classes reported higherlevels of risky alcohol consumption.

Short communication: Persistent socio-economic inequality in frequent headache among Danish adolescents from 1991 to 2014.

The association between socio-economic status (SES) and headache among adolescents is an understudied issue, and no study has examined whether such an association changes over time. The aim was to examine trends in socio-economic inequality in frequent headache among 11- to 15-year-olds in Denmark from 1991 to 2014, using occupational social class (OSC) as indicator of SES. The study applies data from the Danish part of the international Health Behaviour in School-aged Children (HBSC) study. HBSC includes nationally representative samples of 11-, 13- and 15-year-olds. This study combines data from seven data survey years from 1991 to 2014, participation rate 88.6%, n=31,102. We report absolute inequality as per cent difference in frequent headache between high and low OSC and relative inequality as odds ratio for frequent headache by OSC. In the entire study population, 10.4% reported frequent headache. There was a significant increase in frequent headache from 8.0% in 1991 to 12.9% in 2014, test for trend, p<0.0001. This increasing trend was significant in all OSCs. The prevalence of frequent headache was significantly higher in low than high OSC, OR=1.50 (95% CI: 1.34-1.67). This socio-economic inequality in frequent headache was persistent from 1991 to 2014. There was a significant and persistent socio-economic inequality, i.e. increasing prevalence of frequent headache with decreasing OSC. The association between socio-economic position and headache did not significantly change over time, i.e. the statistical interaction between OSC and survey year was insignificant. The prevalence of frequent headache among adolescents increases with decreasing SES. This socio-economic inequality has been persistent among adolescents in Denmark from 1991 to 2014. Clinicians should be aware of this social inequality.

Increasing prevalence of emotional symptoms in higher socioeconomic strata: Trend study among Danish schoolchildren 1991-2014.

Aims: The aims of this study were: (a) to examine trends in daily emotional symptoms among 11- to 15-year-olds from 1991 to 2014 in Denmark, and (b) to examine trends in social inequality in daily emotional symptoms, that is, whether the differences in prevalence between adolescents with parents of varying occupational social class changed over time. Methods: We combined seven comparable cross-sectional Health Behaviour in School-aged Children surveys (N=31,169). Daily emotional symptoms were measured by the HBSC Symptom Check List and occupational social class (OSC) by students' reports about parents' occupation. We calculated absolute (per cent) differences in emotional symptoms between high and low OSC and relative differences by odds ratio for emotional symptoms by parents' OSC. Results: Eight per cent reported at least one daily emotional symptoms, with an increasing trend from 1991 to 2014 (p<0.001). The prevalence in high, middle and low OSC was 6.2%, 7.4% and 10.6% (p<0.0001). From 1991 to 2014, there was an increase in the prevalence of daily emotional symptoms in high (p<0.0001) and middle (p<0.0001) but not low OSC (p=0.4404). This resulted in a diminishing absolute social inequality in emotional symptoms. The statistical interaction between OSC and survey year was significant (p=0.0023) and suggests a diminishing relative social inequality in emotional symptoms from 1991 to 2014. Conclusions: There was an increasing prevalence of daily emotional symptoms from 1991 to 2014 and a diminishing social inequality in prevalence of daily emotional symptoms in terms of both absolute and relative social inequality.

Dimension of pain-related quality of life and self-reported mental health in men and women of the European Prospective Investigation into Cancer-Norfolk cohort: a population-based cross-sectional study.

Both cognitive and behavioural factors are linked to the experience of pain as well as its interference with quality of life. Psychological distress has been shown to be associated to several emotional and social impairments. Although, the association between pain and mental health has been widely discussed, the understanding of life interference and outcome is not fully understood. This study examined the association of pain dimension and mental health domain in 16,051 participants of the EPIC-Norfolk cohort (mean age = 58.9 ± 9.1 years). Study outcomes were depressive or anxious behaviour and limitations due to emotional problems and impairments in social functioning (mental functional health components of the Short Form-36 (SF-36)). Logistic regression models were constructed controlling for the potentially confounding factors including socio-economic variables (occupational social class, deprivation, marital status, education), lifestyle behaviour (physical activity, smoking, alcohol, dietary) and previous medical history. Strong interference in quality of life due to pain (bottom 20% of pain dimension score of SF-36) was significantly associated with poor MH in men and women (odds ratios (ORs) (95% confidence intervals (CIs)): 1.35 (1.19, 1.54) and 1.39 (1.25, 1.55), respectively; p < 0.0001) in fully adjusted models. Moreover, strong interference due to pain was also significantly associated with poor overall MH including emotional and social functioning (ORs (95% CIs): 1.42 (1.25, 1.62) and 1.39 (1.25, 1.55) respectively; p < 0.0001) in fully adjusted models; subsidiary analysis using linear regression models demonstrated similar results for these domains. Although a strong association has been shown, further research is needed to provide information on the different site and/or causes of pain which would allow stratification. Moreover, assuming a bi-directional nature of both domains, systematic assessment and management of pain have a lot of potential to improve the MH-related quality of life in the general population and vice versa.

Occupational Social Class and Personality Traits in Relation to Leisure-Time Physical Activity Level: Cross-Sectional Results From the Copenhagen Aging and Midlife Biobank.

To investigate separate and combined associations of occupational social class and personality traits with late midlife leisure-time physical activity duration and intensity. Cross-sectional data from the Copenhagen Aging and Midlife Biobank ( N = 4,649) were analyzed using linear regression models with leisure-time physical activity (metric equivalence) as outcome. Low versus high occupational social class was associated with 4% (95% confidence interval [CI] = [3%, 5%]) greater leisure-time physical activity duration, but 2% (CI = [1%, 3%]) lower intensity. Each 10-unit increase in extraversion was associated with 5% (CI = [2%, 8%]) greater duration. Intensity increased by each 10-unit increase in conscientiousness (6%, CI = [4%, 7%]), openness (3%, CI = [1%, 4%]), neuroticism (3%, CI = [1%, 4%]), and extraversion (5%, CI = [4%, 7%]). Conscientiousness was positively associated with duration in low, but not in high, occupational social class (interaction p value = .002). Higher occupational social class was associated with lower leisure-time physical activity duration, but higher intensity. Extraversion was positively associated with duration and intensity. Conscientiousness, openness, and neuroticism were positively associated with intensity. Overall, interactions were not consistent.

Comparing Oral Health Services Use in the Spanish and Immigrant Working Population.

We aim to analyze oral health services use and related factors in the immigrant working population compared to the Spanish counterparts. Cross-sectional study of working population (n = 8591) that responded Spanish National Health Survey (SNHS), 2011-2012. The association between oral health services use and migration status was estimated using logistic regression. Immigrant men presented a greater probability of oral health service use a year or more prior (aOR 1.63; 95% CI 1.26-2.02), independently of oral health, sociodemographic and socioeconomic characteristics. In immigrant women, greater probability of use of oral health services one year or more prior disappeared after adjusting for the same variables (aOR 1.15; 95% CI 0.91-1.45). Occupational social class and education level could explain better a high percentage of oral health service use one year or more prior in immigrant women but there is a persistent inequality in oral health service use in immigrant men.

Intergenerational social mobility and subjective wellbeing in later life

Whereas a great deal of literature has been devoted to investigating the link between intergenerational social mobility and health, the few studies that have examined the association between social mobility and life satisfaction have produced conflicting findings. In the present study, we attempt to rectify several shortcomings common to previous work by examining the association between intergenerational social mobility and both life satisfaction and self-rated health as measured in later-life. Our sample consisted of individuals born in Scotland in 1936, who took part in the Scottish Mental Survey 1947 and were subsequently followed-up into later-life. Regression analyses demonstrated that satisfaction with life at age 78 was not significantly predicted by childhood or adulthood socioeconomic status, or by the amount of social mobility experienced from parental occupational social class. In contrast, self-rated health at age 78 was significantly predicted by adult socioeconomic status and by education, but not by social mobility from parental occupational social class. These results suggest that efforts to promote upwards social mobility may not result in better subjective wellbeing, despite the apparent benefits for health.

Trends in socioeconomic inequalities in oral health among 15-year-old Danish adolescents during 1995-2013: A nationwide, register-based, repeated cross-sectional study.

Scandinavian welfare states, despite having better population oral health than less egalitarian societies, are characterized by ubiquitous social gradients and large relative socioeconomic inequalities in oral health. However, trends in these inequalities among Scandinavian children and adolescents have not been studied in detail. To describe the associations between socioeconomic position (SEP) and oral health in adolescents and to investigate the trends in these associations between 1995 and 2013. Nationwide repeated cross-sectional studies (using individual-level data) were conducted on 15-year-olds in Denmark from 1995, 2003, and 2013 (N=154,750). Dental data were obtained from the national dental register of the Danish Health Authority (Sundhedsstyrelsens Centrale Odontologiske Register [SCOR]) and data on social variables from administrative registers at Statistics Denmark. SEP measures included previous year's parental education (highest attained educational level by either of the parents), income (equivalized household disposable income), and occupational social class (highest recorded occupational class between the parents). Covariates were immigration status, country of origin, number of children and persons in the family, and household type. The outcome was dental caries experience, represented by the decayed, missing, and filled surfaces (DMFS) index. Negative binomial regression models were used to examine the association between DMFS count and each of the explanatory variables separately while accounting for cluster-correlated family data. Furthermore, hierarchical multiple regressions of DMFS on SEP indicators-using the zero-inflated negative binomial (ZINB) distribution as the outcome distribution-were estimated while successively adjusting for the potential effects of the included covariates. Caries prevalence declined from 71% in 1995 to 63% in 2003 and 45% in 2013. Separate assessment of each covariate showed statistically significant graded associations between each covariate and DMFS count at all time points. Similarly, in the ZINB models, in all 3 years, clear gradients were observed in terms of caries differentials in all three SEP categories, with statistically significant associations (Type 3 P values, <.0001) even after adjustment for all other covariates. For instance, in 2013, even among adolescents with positive caries experience, being of lower occupational social class was associated with up to 2.4-fold (95% confidence interval [CI]: 2.2-2.6) higher caries experience. Between 1995 and 2013, relative inequalities increased in all SEP categories, while absolute inequalities decreased in the education and occupation categories. Considerable progress has been made in reducing dental caries rates among Danish adolescents; however, this progress has benefited the disadvantaged social groups less than the better-off groups.
