Psychological distress from early adulthood to early old age: Evidence from the 1946, 1958 and 1970 British birth cohorts

Background: Existing evidence on profiles of psychological distress across adulthood uses cross-sectional or longitudinal studies with short observation periods. The objective of this research was to study the profile of psychological distress within the same individuals from early adulthood to early old age across three British birth cohorts. Methods We used data from three British birth cohorts: born in 1946 (n = 3093), 1958 (n = 13 250) and 1970 (n = 12 019). The profile of psychological distress - expressed both as probability of being a clinical case or a count of symptoms based on comparable items within and across cohorts - was modelled using the multilevel regression framework. Results In both 1958 and 1970 cohorts, there was an initial drop in the probability of being a case between ages 23-26 and 33-34. Subsequently, the predicted probability of being a case increased from 12.5% at age 36 to 19.5% at age 53 in the 1946 cohort; from 8.0% at age 33 to 13.7% at age 42 in the 1958 cohort and from 15.7% at age 34 to 19.7% at age 42 in the 1970 cohort. In the 1946 cohort, there was a drop in the probability of caseness between ages 60-64 and 69 (19.5% v. 15.2%). Consistent results were obtained with the continuous version of the outcome. Conclusions Across three post-war British birth cohorts midlife appears to be a particularly vulnerable phase for experiencing psychological distress. Understanding the reasons for this will be important for the prevention and management of mental health problems. [Abstract sourced from the publisher version of the article]

Does an elite education benefit health? Findings from the 1970 British Cohort Study

Background Attending private school or a higher status university is thought to benefit future earnings and occupational opportunities. We examined whether these measures were beneficially related to health and selected health-related behaviours in midlife. Methods Data were from up to 9799 participants from the 1970 British birth Cohort Study. The high school attended (private, grammar, or state) was ascertained at 16 years, and the university attended reported at 42 years (categorised as either a higher (Russell Group institution) or normal status institutions). Self-reported health, limiting illness, and BMI were reported at 42 years, along with television viewing, take-away meal consumption, physical inactivity, smoking, and high risk alcohol drinking. Associations were examined using multiple regression models, adjusted for gender, childhood socioeconomic, health, and cognitive measures. Results Private school and higher status university attendance were associated with favourable self-rated health, lower BMI, and beneficially associated with health related-behaviours. For example, private school attendance was associated with 0.56 (95% CI: 0.48, 0.65) odds of lower self-rated health (OR for higher status university: 0.32 (0.27, 0.37)). Associations were largely attenuated by adjustment for potential confounders, except for those of private schooling and higher status university attendance with lower BMI and television viewing, and less frequent take-away meal consumption. Conclusions Private school and higher status university attendance were related to better self-rated health, lower BMI, and multiple favourable health behaviours in midlife. Findings suggest that type or status of education may be an important under-researched construct to consider when documenting and understanding socioeconomic inequalities in health

Dynamics between psychological distress and body mass index throughout adult life; evidence from 3 large cohort studies

Background: Associations between body mass index (BMI) and psychological distress (PD) have been reported; however, few longitudinal studies have accounted for likely life-course differences in BMI and PD stability, consistency, and their interplay across time. Methods: Via random intercepts cross-lagged panel models, we assessed the predictive effects (from BMI to PD or vice-versa) across the last two centuries in the Coronary Artery Risk Development in Young Adults [CARDIA, beginning in 1985-6] study using the Center for Epidemiological Studies-Depression Scale [CES-D], and in the National Child Development Study [NCDS, beginning in 1958] and British Cohort Study [BCS, beginning in 1970] using the Malaise Inventory [MI]), assessed at least 4 times in adult life. Findings: In CARDIA (n = 4724), NCDS58 (n = 7149) and BCS70 (n = 5967), autoregressive effects were stronger for BMI than for PD, meaning that carry-over effects from one occasion to the next were larger for BMI than for PD. Small interindividual correlations between traits of higher BMI and higher PD were identified among females (rfemale<|0⋅2|) but not males (rmale<|0⋅03|) in CARDIA and NCDS. Cross-lagged effects were very weak or close to zero (standardized effects η<|0⋅1|). Interpretation: In the United States, depressive symptoms and BMI were positively correlated at the trait level among females. In the United Kingdom, relationships between PD and BMI were inconsistent between generations, with effect sizes of unlikely clinical importance, indicating negligible dominance of an intraindividual effect of BMI on PD or vice versa.publishedVersio

Measuring stigma in children receiving mental health treatment: Validation of the Paediatric Self-Stigmatization Scale (PaedS)

BACKGROUND: Research on the impact of stigma associated with mental illness in children is scarce. Considering the known negative effects of stigma associated with mental illness in adults, it is crucial to explore the stigma experienced by children who access mental health treatment. However, no scale measuring self-stigmatization in younger children is available to date. This study aimed to develop and validate such a scale, the Paediatric Self-Stigmatization Scale (PaedS). METHODS: A total of 156 children (119 receiving outpatient and 37 receiving inpatient treatment), aged 8-12 years, completed the PaedS, the Self-Perception Profile for Children and the Pediatric Quality of Life Inventory (PedsQL - Child Report, ages 8-12). In addition, parents completed the PedsQL (Parent Report for Children, ages 8-12), the Strengths and Difficulties Questionnaire (SDQ) and a modified subscale of the PaedS measuring the children's rejection by others due to their mental health difficulties. RESULTS: A confirmatory factor analysis showed that a four-factor structure, comprising Societal Devaluation, Personal Rejection, Self-Stigma and Secrecy scales, had excellent fit to the data (CFI=0.95; TLI=0.95; RMSEA=0.05). Child-reported PaedS scores were positively correlated with parental-reported PaedS scores and negatively with PedsQL, the SDQ, and 5 out of 6 subscales of the Self-Perception Profile for Children, suggesting adequate convergent validity (all P-values<0.05). CONCLUSIONS: The PaedS is a valid instrument, which is hoped to advance the understanding of self-stigmatization in children with mental health difficulties and contribute to its prevention

Missing at random assumption made more plausible:evidence from the 1958 British birth cohort

ABSTRACT Objective : Non-response is unavoidable in longitudinal surveys. The consequences are lower statistical power and the potential for bias. We implemented a systematic data-driven approach to identify predictors of non-response in the National Child Development Study (NCDS; 1958 British birth cohort). Such variables can help make the missing at random assumption more plausible, which has implications for the handling of missing data Study Design and Setting : We identified predictors of non-response using data from the 11 sweeps (birth to age 55) of the NCDS (n = 17,415), employing parametric regressions and the LASSO for variable selection. Results : Disadvantaged socio-economic background in childhood, worse mental health and lower cognitive ability in early life, and lack of civic and social participation in adulthood were consistently associated with non-response. Using this information, along with other data from NCDS, we were able to replicate the “population distribution” of educational attainment and marital status (derived from external data), and the original distributions of key early life characteristics. Conclusion : The identified predictors of non-response have the potential to improve the plausibility of the missing at random assumption. They can be straightforwardly used as “auxiliary variables” in analyses with principled methods to reduce bias due to missing data

Experience of stigmatization in children receiving inpatient and outpatient mental health treatment: a longitudinal study

Mental health-related stigma is poorly understood, and minimal research has focused on the experience of stigma from children’s perspectives. We sought to investigate whether children treated as inpatients and outpatients had different experiences of stigma over time and whether stigma is linked to global functioning cross-sectionally and longitudinally. Children, aged 8–12 years, receiving treatment within a national specialist mental health inpatient unit were matched for age, gender and diagnosis with children receiving outpatient treatment (N = 64). Validated measures of stigma, global functioning and symptom severity were collected at the start of treatment and upon discharge from the ward for inpatients, and a similar timeframe for their individually matched outpatients. Latent change score models and partial correlation coefficients were employed to test our hypotheses. No differences in most aspects of stigma between children treated as inpatients and outpatients were observed, except for personal rejection at baseline and self-stigma at follow-up favouring outpatients. A reduction in stigma was observed in societal devaluation, personal rejection and secrecy for inpatients, and self-stigma and secrecy for outpatients between the two assessments. Societal devaluation declined at a higher rate among inpatients compared to outpatients, albeit reductions in stigma were comparable for all remaining measures. No association was found between the change in stigma and change in global functioning. Future research may offer further insights into the development and maintenance of stigma and identify key targets for anti-stigma interventions to reduce its long-term impact. © 2021, The Author(s)

Inflammation, coagulation and risk of locomotor disability in elderly women: findings from the British Women’s Heart and Health Study

This study investigated associations between chronic inflammation and coagulation and incident locomotor disability using prospective data from the British Women’s Heart and Health Study. Locomotor disability was assessed using self-reported questionnaires in 1999/2000, and 3 and 7 years later. Scores for inflammation and coagulation were obtained from summation of quartile categories of all available biomarkers from blood samples taken at baseline. 534 women developed locomotor disability after 3 years, 260 women after 7 years, while 871 women remained free of locomotor disability over the whole study period. After adjustment for demographic characteristics, lifestyle factors and health conditions, we found associations between inflammation and incident locomotor disability after three (OR per unit increase in score = 1.08, 95 % confidence interval (CI): 1.03, 1.13) and 7 years (OR = 1.10, 95 % CI: 1.03, 1.18) and between coagulation and incident locomotor disability after 3 (OR = 1.06, 95 % CI: 0.98, 1.14) and 7 years (OR = 1.09, 95 % CI: 1.00, 1.18). This corresponds to ORs between 1.8 and 2.4 comparing women with highest to lowest inflammation or coagulation scores. These results support the role of inflammation and coagulation in the development of locomotor disability in elderly women irrespective of their lifestyle factors and underlying age-related chronic diseases
