Insights
Birth order may influence psychopathology, but depression and alcohol dependence are common in adults regardless of sibling position. Dissociative disorders were more prevalent in first-born children in the child psychiatry group.
Area of Science:
- Psychiatry
- Developmental Psychology
- Behavioral Science
Background:
- Sibling ranking (birth order) is linked to intellectual functioning, personality, behavior, and psychopathology.
- Understanding these associations is crucial for comprehensive psychiatric care.
Purpose of the Study:
- To investigate the relationship between birth order and the development of psychopathology.
- To analyze psychiatric diagnoses in relation to birth order among patients in a teaching hospital's psychiatry services.
Main Methods:
- A hospital-based, cross-sectional study utilizing retrospective file review.
- Compared patient variables (age of onset, birth order, family type, family history) with psychiatric diagnoses (ICD-10).
- Statistical analysis included descriptive statistics and one-way ANOVA using SPSS 13.
Main Results:
- Adult general psychiatry patients (n=527) had a mean age of onset of 33.01 years; child cases (n=47) at 11.68 years; substance abuse cases (n=110) at 26.74 years.
- Depression, anxiety, and somatoform disorders were common in adult patients irrespective of birth order.
- Dissociative disorders were most prevalent in first-born children (36.7%) among child cases, while alcohol dependence was the maximum diagnosis across all birth orders in substance abuse cases.
Conclusions:
- Depression and alcohol dependence are the most frequent diagnoses in adult psychiatric patients, independent of their birth order.
- Specific birth orders may correlate with certain diagnoses, such as dissociative disorders in first-born children.
Context:
Ordinal position the child holds within the sibling ranking of a family is related to intellectual functioning, personality, behavior, and development of psychopathology.
Aim:
To study the association between birth order and development of psychopathology in patients attending psychiatry services in a teaching hospital.
Settings And Design:
Hospital-based cross-sectional study.
Materials And Methods:
Retrospective file review of three groups of patients was carried out. Patient-related variables like age of onset, birth order, family type, and family history of mental illness were compared with psychiatry diagnosis (ICD-10) generated.
Statistical Analysis:
SPSS 13; descriptive statistics and one-way analysis of variance (ANOVA) were used.
Results:
Mean age of onset of mental illness among the adult general psychiatry patients (group I, n = 527) was found to be 33.01 ± 15.073, while it was 11.68 ± 4.764 among the child cases (group II, n = 47) and 26.74 ± 7.529 among substance abuse cases (group III, n = 110). Among group I patients, commonest diagnosis was depression followed by anxiety and somatoform disorders irrespective of birth order. Dissociative disorders were most prevalent in the first born child (36.7%) among group II patients. Among group III patients, alcohol dependence was maximum diagnosis in all birth orders.
Conclusions:
Depression and alcohol dependence was the commonest diagnosis in adult group irrespective of birth order.
