Family socioeconomic position in early life and onset of depressive symptoms and depression:a prospective cohort study
PURPOSE: To investigate whether low parental socioeconomic position (SEP) at birth is associated only with early-onset depressive symptoms in offspring. METHODS: This prospective cohort study used data on 9193 individuals (4768 females, 4425 males) from the Avon Longitudinal Study of Parents and Children. Depressive symptoms during three age periods (10â12, 12â16, 16â20Â years) were assessed using the Short Mood and Feelings Questionnaire, and ICD-10 depression at age 18 was assessed using the Clinical Interview Schedule-Revised. RESULTS: Low SEP was associated with increased incidence rates of depressive symptoms in all age periods, with indicators of low standard of living showing the strongest associations. For instance, incidence rate ratios for material hardship were 1.75 (95% CI [1.42â2.15]) at 10â12Â years, 1.36 (1.16â1.61) at 12â16Â years and 1.39 (1.21â1.59) at 16â20Â years. Low SEP was also associated with increased odds of ICD-10 depression at 18Â years, ranging from ORÂ =Â 1.20 (95% CI [0.94â1.52]) for manual social class to 1.74 (1.35â2.24) for material hardship. CONCLUSIONS: There was no evidence that depressive symptoms can be âsubtypedâ by the age of onset, because the association with low SEP was evident for early- and later-onset symptoms. If socioeconomic inequalities in early life have long-term adverse impacts on mental health, policies addressing these inequalities could benefit the mental health of the population.

Early Childhood Father Absence and Depressive Symptoms in Adolescent Girls from a UK Cohort:The Mediating Role of Early Menarche
# The Author(s) 2014. This article is published with open access at Springerlink.com Abstract Absence of the biological father in early childhood has been linked to depressive symptoms in mid-adolescent girls. Earlier studies have linked father absence to early timing of menarche, and early menarche is a risk factor for increased depressive symptoms in adolescence. No studies, however, have examined whether the association between father ab-sence and depressive symptomsmay be explained by the early onset of menarche. This study investigated whether age at menarche mediates the association between father absence in early childhood (birth to 5 years) and depressive symptoms in adolescent girls aged 14 years. The study sample comprised 7056 girls from a large UK birth cohort (Avon Longitudinal Study of Parents and Children) who provided data on age at onset of menarche and depressive symptoms assessed using the Short Mood and Feelings Questionnaire at 14 years. Mothers provided data on father absence from the birth of the study child up to 10 years. Using structural equation modelling, we found that 15 % of the total estimated associ-ation between father absence in early childhood and depres-sive symptoms at 14 years was explained by early age at menarche. In addition to the mediated effect, father absence was linked to an 11 % increase in depressive symptoms in adolescence. The findings suggest that early age at menarche is one of the pathways linking early childhood father absence and depressive symptoms in mid-adolescent girls. Preventive strategies could be targeting young girls at risk for depressive symptoms as a function of stressful family factors (e.g., bio-logical father absence) and earlier menarche
Challenging the view that lack of fibre causes childhood constipation
Objectives: To assess evidence supporting the view that âlow fibre causes childhood constipationâ.
Design: Triangulation integrated three approaches: a systematic review NICE guideline CG99 examining effectiveness of increasing fibre; a cohort study, Avon Longitudinal Study of Parents and Children (ALSPAC), to assess if constipation (or hard stools) can precede fibre intake at weaning; and a literature search for twin studies to calculate heredity.
Setting: CG99 examined the literature regarding the effectiveness of increasing fibre. ALSPAC asked parents about: hard stools at 4 weeks, 6 months and 2.5 years and constipation at age 4â10 years, as well as fibre intake at 2 years. Twin studies and data from ALSPAC were pooled to calculate concordance of constipation comparing monozygotic and dizygous twin pairs.
Participants: CG99 reported six randomised controlled trials (RCTs). ALSPAC hard stool data from 6796 children at 4 weeks, 9828 at 6 months and 9452 at 2.5 years plus constipation data on 8401 at 4â10 years were compared with fibre intake at 2 years. Twin studies had 338 and 93 twin pairs and ALSPAC added a further 45.
Results: Increasing fibre did not effectively treat constipation. Hard stools at 4 weeks predated fibre and at 6 months predicted lower fibre intake at 2 years (p=0.003). Heredity explained 59% of constipation.
Conclusions: RCTs indicate that increasing fibre is not an effective treatment for constipation in children. Hard stools can precede and predict later fibre intake. Genetic inheritance explains most childhood constipation. Extended treatment with stool softeners may improve fibre intake and limit long-term damaging sequelae of constipation
Examining the role of maternal religiosity in offspring mental health using latent class analysis in a UK prospective cohort study
Stressful events in early childhood and developmental trajectories of bedwetting at school age
Objective To examine whether early stressful events are associated with developmental trajectories of bedwetting.âMethodsâThis is a prospective cohort study comprising 8,761 participants from the Avon Longitudinal Study of Parents and Children. Stressful events were measured using a maternal questionnaire completed at 3 time points before their child was 4 years old. The association between stressful events and trajectories of bedwetting from 4 to 9 years was examined using multinomial regression.âResultsâThe association with stressful events was strongest for the frequent persistent bedwetting trajectory (wetting at least twice a week up to age 9). A 1 standard deviation increase in the stressful events score was associated with a 29% (13â47%) increase in the odds of experiencing frequent persistent bedwetting compared with normal attainment of nighttime bladder control.âConclusionsâClinicians and parents should be aware that continence is a developmental outcome that is associated with high levels of stress in the family
Peer victimisation during adolescence and its impact on depression in early adulthood:prospective cohort study in the United Kingdom
Objective:
To investigate the strength of the association between victimisation by peers at age 13 years and depression at 18 years.
Design:
Longitudinal observational study.
Setting:
Avon Longitudinal Study of Parents and Children, a UK community based birth cohort.
Participants: 6719 participants who reported on peer victimisation at age 13 years.
Main outcome measures:
Depression defined according to international classification of diseases, 10th revision (ICD-10) criteria, assessed using the clinical interview schedule-revised during clinic assessments with participants when they were aged 18 years. 3898 participants had data on both victimisation by peers at age 13 years and depression at age 18 years.
Results:
Of the 683 participants who reported frequent victimisation at age 13 years, 101 (14.8%) were depressed according to ICD-10 criteria at 18 years; of the 1446 participants reporting some victimisation at age 13 years, 103 (7.1%) were depressed at age 18 years; and of the 1769 participants reporting no victimisation at age 13 years, 98 (5.5%) were depressed at age 18 years. Compared with children who were not victimised those who were frequently victimised by peers had over a twofold increase in odds of depression (odds ratio 2.96, 95% confidence interval 2.21 to 3.97, P<0.001). This association was slightly reduced when adjusting for confounders (2.32, 1.49 to 3.63, P<0.001). The population attributable fraction suggested that 29.2% (95% confidence interval 10.9% to 43.7%) of depression at age 18 years could be explained by peer victimisation if this were a causal relation.
Conclusion:
When using observational data it is impossible to be certain that associations are causal. However, our results are consistent with the hypothesis that victimisation by peers in adolescence is associated with an increase in the risk of developing depression as an adult
