Reduced red-cell folate in mania

Hasanah CI, Khan UA, Musalmah M, Razali SM

J Affect Disord, 1997 Nov;46(2):95-9.
PMID: 9479613

Forty-five hospitalised patients with DSM-III-R diagnosis of mania, were found to have a mean red-cell folate level of 193 nmol/l, as compared to 896 nmol/l in the control group (P < 0.00001). Assessment of serum folate in both groups showed no significant differences in the levels. Furthermore the manic patients and the controls were matched by the socio-economic status. This indicated that the reduced red-cell folate in mania is associated with the illness and not due to reduced absorption or dietary deficiency of folate. Considering previous studies that showed reduced red-cell folate in depression, our findings suggest that reduced red-cell folate occurred in both phases of bipolar disorders.
Fulltext The bidirectional temporal relationship between parenting stress and child maltreatment: A cross-lagged study based on intervention and cohort data

Han Q, Jocson R, Kunovski I, Raleva M, Juhari R, Okop K, et al.

J Affect Disord, 2024 Jun 01;354:302-308.
PMID: 38479502 DOI: 10.1016/j.jad.2024.03.063

BACKGROUND: Parenting stress has long been proposed as a major risk factor for child maltreatment. However, there is a lack of evidence from existing studies on the temporal sequence to establish a causal relationship. This study aims to examine bidirectional temporal relationships between parenting stress and child maltreatment.
METHODS: Longitudinal data from two different sources were analysed: a pre-post study of an online parenting programme conducted across six countries - the ePLH Evaluation Study, and a prospective cohort study in the United States - LONGSCAN. Cross-lagged panel model on parenting stress and child maltreatment was used in each dataset.
RESULTS: Based on repeatedly measured data of 484 caregivers in the ePLH study across five time points (every two weeks), we found that parenting stress at an earlier time point predicted later child maltreatment (IRR = 1.14, 95 % CI: 1.10,1.18). In addition, the occurrence of child maltreatment was associated with higher subsequent short-term parenting stress (IRR = 1.04, 95 % CI: 1.01,1.08) and thus could form a vicious circle. In the LONGSCAN analysis with 772 caregivers who were followed up from child age of 6 to child age of 16, we also found parenting stress at an earlier time point predicted later child maltreatment (β = 0.11, 95 % CI: 0.01,0.20), but did not observe an association between child maltreatment and subsequent long-term parenting stress.
LIMITATIONS: Potential information bias on the measurements.
CONCLUSIONS: This study provides evidence for a bidirectional temporal relationship between parenting stress and child maltreatment, which should be considered in parenting intervention programmes.
Cross-cultural and social diversity of prevalence of postpartum depression and depressive symptoms

Halbreich U, Karkun S

J Affect Disord, 2006 Apr;91(2-3):97-111.
PMID: 16466664 DOI: 10.1016/j.jad.2005.12.051

BACKGROUND:
The prevalence of postpartum depression (PPD) is currently considered to be 10-15%. Most studies were performed with a brief unidimensional instruments (mostly the Edinburgh Postnatal Depression Scale-EPDS) with focus on depression and not on other symptoms and disorders. Most cited studies were conducted in Western economically developed countries.

METHODS:
We reviewed the literature on prevalence of postpartum depression and depressive symptoms in a wide range of countries.

RESULTS:
143 studies were identified reporting prevalence in 40 countries. It is demonstrated that there is a wide range of reported prevalence of PPD ranging from almost 0% to almost 60%. In some countries like Singapore, Malta, Malaysia, Austria and Denmark there are very few reports of PPD or postpartum depressive symptoms, whereas in other countries (e.g. Brazil, Guyana, Costa Rica, Italy, Chile, South Africa, Taiwan and Korea) reported postpartum depressive symptoms are very prevalent.

CONCLUSIONS:
We believe that the widely cited mean prevalence of PPD-10-15% is not representative of the actual global prevalence and magnitude of the problem, due to the wide range of reports. The variability in reported PPD might be due to cross-cultural variables, reporting style, differences in perception of mental health and its stigma, differences in socio-economic environments (e.g. poverty, levels of social support or its perception, nutrition, stress), and biological vulnerability factors. The elucidation of the underlying processes of this variability as well as the diversity of postpartum normal versus abnormal expressions of symptoms may contribute to better understanding of the diversified ante, peri- and postpartum phenomena.
Non-binary gender, vulnerable populations and mental health during the COVID-19 pandemic: Data from the COVID-19 MEntal health inTernational for the general population (COMET-G) study

Fountoulakis KN, Vrublevska J, Abraham S, Adorjan K, Ahmed HU, Alarcón RD, et al.

J Affect Disord, 2024 May 01;352:536-551.
PMID: 38382816 DOI: 10.1016/j.jad.2024.02.050

BACKGROUND: The COVID-19 pandemic has brought significant mental health challenges, particularly for vulnerable populations, including non-binary gender individuals. The COMET international study aimed to investigate specific risk factors for clinical depression or distress during the pandemic, also in these special populations.
METHODS: Chi-square tests were used for initial screening to select only those variables which would show an initial significance. Risk Ratios (RR) were calculated, and a Multiple Backward Stepwise Linear Regression Analysis (MBSLRA) was followed with those variables given significant results at screening and with the presence of distress or depression or the lack of both of them.
RESULTS: The most important risk factors for depression were female (RR = 1.59-5.49) and non-binary gender (RR = 1.56-7.41), unemployment (RR = 1.41-6.57), not working during lockdowns (RR = 1.43-5.79), bad general health (RR = 2.74-9.98), chronic somatic disorder (RR = 1.22-5.57), history of mental disorders (depression RR = 2.31-9.47; suicide attempt RR = 2.33-9.75; psychosis RR = 2.14-10.08; Bipolar disorder RR = 2.75-12.86), smoking status (RR = 1.15-5.31) and substance use (RR = 1.77-8.01). The risk factors for distress or depression that survived MBSLRA were younger age, being widowed, living alone, bad general health, being a carer, chronic somatic disorder, not working during lockdowns, being single, self-reported history of depression, bipolar disorder, self-harm, suicide attempts and of other mental disorders, smoking, alcohol, and substance use.
CONCLUSIONS: Targeted preventive interventions are crucial to safeguard the mental health of vulnerable groups, emphasizing the importance of diverse samples in future research.
LIMITATIONS: Online data collection may have resulted in the underrepresentation of certain population groups.
Cultural and interpersonal risk factors for suicide ideation and suicide attempts among Muslim college students from 11 nations

Eskin M, Baydar N, Harlak H, Hamdan M, Mechri A, Isayeva U, et al.

J Affect Disord, 2021 11 01;294:366-374.
PMID: 34315098 DOI: 10.1016/j.jad.2021.07.050

BACKGROUND: Research on suicidality in low to middle-income countries is scarce. We addressed this issue by investigating suicidality in a cross-national college student samples from 11 predominantly low to middle-income majority Muslim countries.
METHODS: The sample consisted of 7427 college students (56% female) who reported to be affiliated with Islam. Data on self-construal, social support, negative life-events, acceptability of suicide, suicidal ideation, and suicide attempts were collected with self-administered questionnaires.
RESULTS: Acceptability of suicide and the experience of negative life-events were positively, and perceived social support was negatively associated with suicidal ideation. Interdependent self-construal was negatively related to the acceptability of suicide and positively associated with perceived social support, implying a negative indirect effect on suicidal ideation although its direct effect was positive. The number of negative life-events was the strongest positive predictor of ever attempting suicide. The interdependent self-construal moderated the association of negative life-events with suicide attempts.
LIMITATIONS: Cross-sectional and self-report nature of the study were its major limitations. Participants may have suppressed their responses about suicide because of religious and legal reasons.
CONCLUSION: Remarkable similarities across 11 country samples emerged in the linkages between cultural and interpersonal factors with suicidality. Our findings highlight the value of a nuanced approach to suicidality, that can recognize the differences in the processes associated with suicidal ideation and suicide attempts, as well as the need to consider the interplay of a broad range of personal, interpersonal, and cultural influences.

Relationship between sunlight and the age of onset of bipolar disorder: an international multisite study

Bauer M, Glenn T, Alda M, Andreassen OA, Angelopoulos E, Ardau R, et al.

J Affect Disord, 2014;167:104-11.
PMID: 24953482 DOI: 10.1016/j.jad.2014.05.032

The onset of bipolar disorder is influenced by the interaction of genetic and environmental factors. We previously found that a large increase in sunlight in springtime was associated with a lower age of onset. This study extends this analysis with more collection sites at diverse locations, and includes family history and polarity of first episode.

Balakrishnan V, Ng KS, Kaur W, Govaichelvan K, Lee ZL

J Affect Disord, 2022 Feb 01;298(Pt B):47-56.
PMID: 34801606 DOI: 10.1016/j.jad.2021.11.048

BACKGROUND: This systematic review and meta-analysis aim to synthesize the extant literature reporting the effects of COVID-19 pandemic based on the pooled prevalence of depression among affected populations in Asia Pacific, as well as its risk factors.
METHOD: A systematic review and meta-analysis approach was adopted as per the PRISMA guidelines, targeting articles published in PubMed, Google Scholar and Scopus from January 2021 to March 30, 2021. The screening resulted in 82 papers.
RESULTS: The overall pooled depression prevalence among 201,953 respondents was 34% (95%CI, 29-38, 99.7%), with no significant differences observed between the cohorts, timelines, and regions (p > 0.05). Dominant risk factors found were fear of COVID-19 infection (13%), gender (i.e., females; 12%) and deterioration of underlying medical conditions (8.3%), regardless of the sub-groups. Specifically, fear of COVID-19 infection was the most reported risk factor among general population (k = 14) and healthcare workers (k = 8). Gender (k = 7) and increased workload (k = 7) were reported among healthcare workers whereas education disruption among students (k = 7).
LIMITATION: The review is limited to articles published in three electronic databases. Conclusion The pandemic has caused depression among the populations across Asia Pacific, specifically among the general population, healthcare workers and students. Immediate attention and interventions from the concerned authorities are needed in addressing this issue.
