Relationship between premenstrual syndrome and basic personality traits: a cross-sectional study

ABSTRACT BACKGROUND: Although many studies have investigated premenstrual syndrome and related factors, there is still only a limited number of studies investigating the relationship between premenstrual syndrome and basic personality traits. This study was conducted to investigate the association between premenstrual syndrome and basic personality traits among university students. DESIGN AND SETTING: Cross-sectional analytical study conducted in a city in western Turkey. METHODS: The Premenstrual Syndrome Scale, the Basic Personality Traits Scale and a questionnaire on sociodemographic characteristics developed by the present researchers were applied to 490 female students at the College of Health Sciences of a state university. RESULTS: Premenstrual syndrome was more common among students living in rural areas (65.1%), students with chronic diseases (74.1%), students who suffered from menstrual cramps (61.1%), students who used cigarettes (72.1%) and students with alcohol intake (65.5%). In the final model of the logistic regression analysis, presence of pain during the menstrual period increased the risk of presence of PMS by a factor of 1.554 (95% confidence interval, CI: 1.033-2.336; P = 0.034) and high scores on the total basic personality traits scale increased it by a factor of 1.016 (95% CI: 1.002-1.030; P = 0.029). The prevalence of premenstrual syndrome was found to be higher among students who were less extrovert (P = 0.007) and less conscientious (P = 0.001); and among students with higher neuroticism (P = 0.000) and negative valance (P = 0.000). CONCLUSION: This study demonstrates that personality may be associated with premenstrual syndrome.

Bipolar disorder and Premenstrual Syndrome or Premenstrual Dysphoric Disorder comorbidity: a systematic review / Comorbidade entre o Transtorno Bipolar e Síndrome Pré-menstrual ou Transtorno Disfórico Pré-menstrual: uma revisão sistemática

OBJECTIVE: This article aims to review the comorbidity of premenstrual syndrome (PMS) or premenstrual dysphoric disorder (PMDD) and bipolar disorder (BD), identify variables requiring further investigation and to remind physicians that special care is required for diagnosis and therapy. METHOD: A systematic review of articles published from 1987 to February 2012 was conducted in the Medline database with the following terms: (premenstrual syndrome OR premenstrual dysphoric disorder OR premenstrual) AND (bipolar OR mania OR manic). Seventeen articles were analyzed. RESULTS: PMS and PMDD were most often comorbid among BD-II patients and vice versa. Moreover, patients with PMS or PMDD also have an increased risk of having BD-I. In addition, bipolar women susceptible to hormonal changes exhibit more severe symptoms, more frequent relapses and a worse therapeutic response. CONCLUSION: Future investigations should attempt to stabilize hormonal levels through the continuous use of contraceptives to target a reduction in symptom severity. In addition, psychiatrists should note menstrual period dates and compare symptom intensity between the luteal and follicular phases. Finally, PMS and PMDD patients should be studied separately.

OBJETIVO: Esse artigo tem como objetivo revisar a comorbidade entre a Síndrome Pré-Menstrual (SPM) ou Transtorno Disfórico Pré-Menstrual (TDPM) e o Transtorno Bipolar (TB), identificar as variáveis que exigem uma investigação mais aprofundada e lembrar os médicos que as mulheres necessitam de cuidados especiais para diagnóstico e tratamento. MÉTODO: Foi realizada uma revisão sistemática de 1987 a fevereiro de 2012 através da base de dados Medline utilizando os seguintes descritores: (premenstrual syndrome OR premenstrual dysphoric disorder OR premenstrual) AND (bipolar OR mania OR manic). Dezessete artigos foram analisados. RESULTADOS: Pacientes com SPM ou TDPM possuem comorbidade com TB-II com maior frequência e vice-versa. Mulheres com SPM ou TDPM também possuem um risco aumentado apresentar TB-I. Além disso, as mulheres bipolares suscetíveis a mudanças hormonais cursam com sintomas mais graves, recaídas mais freqüentes e pior resposta terapêutica. CONCLUSÃO: Futuras investigações devem estabilizar os níveis hormonais com o uso contínuo de contraceptivos na tentativa de diminuir a gravidade dos sintomas. Além disso, psiquiatras devem observar os períodos menstruais e comparar a intensidade dos sintomas entre as fases folicular e lútea. Pacientes com SPM ou TDPM devem ser estudadas separadamente.

Premenstrual symptoms and syndrome according to age at menarche in a 1982 birth cohort in southern Brazil

Premenstrual symptoms and syndrome were studied in young women who have been followed since birth. Data were collected on the intensity of four symptoms: irritability, anxiety or stress, depressed mood, and affective lability. Premenstrual syndrome was defined according to intensity of symptoms. Association between age at menarche and premenstrual symptoms and syndrome were investigated through Poisson regression. Adjusted analysis was conducted, controlling for possible confounding factors. The symptoms most frequently reported by the women from the 1982 Pelotas, Rio Grande do Sul, Brazil, birth cohort who were interviewed in 2004-2005 were: irritability (52.3 percent) and anxiety (40.2 percent). The prevalence rates for moderate and severe premenstrual syndrome were 13.4 percent and 5.8 percent, respectively. Mean age at menarche was 12.4 (± 1.5) years. Prevalence rates for symptoms and premenstrual syndrome were higher in women whose age at menarche was less than 11 years, but this difference was not statistically significant. Information on symptoms and premenstrual syndrome is scarce in other studies.

Os sintomas e a síndrome pré-menstrual foram estudados em mulheres jovens acompanhadas desde seu nascimento. Foram coletadas informações sobre intensidade de quatro sintomas: irritabilidade; ansiedade ou tensão; humor deprimido e labilidade emocional. Síndrome pré-menstrual foi definida de acordo com a intensidade desses sintomas. A associação entre os sintomas e a síndrome pré-menstrual com a idade da menarca foi investigada por meio de regressão de Poisson, ajustando para possíveis fatores de confusão. Em 76 por cento das mulheres da coorte de Pelotas, Rio Grande do Sul, Brasil, de 1982, que foram acompanhadas até 2004-2005 os sintomas mais freqüentes foram: irritabilidade e ansiedade. A prevalência de síndrome pré-menstrual foi de 13,4 por cento e 5,8 por cento nas intensidades moderada e severa, respectivamente. A idade média da menarca foi de 12,4 (± 1,5) anos. A prevalência dos sintomas pré-menstruais foi mais alta nas mulheres com menarca antes dos 11 anos, mas estas diferenças não foram estatisticamente significativas. Informações sobre sintomas pré-menstruais e síndrome pré-menstrual são escassas em outros estudos populacionais.
