Fatores reprodutivos associados ao excesso de peso em mulheres adultas atendidas pela Estratégia Saúde da Família / Reproductive factors associated with overweight in adult women attended by the Family Health Strategy

Resumo O excesso de peso se destaca como um problema de saúde crescente na população, resultando em ônus para o indivíduo e para a sociedade. O objetivo deste artigo é identificar a associação entre os fatores reprodutivos e o excesso de peso em mulheres de 20 a 59 anos de áreas cobertas pela Unidade de Atenção Primária à Saúde. Trata-se de um estudo transversal com captação domiciliar e coleta de dados em duas Unidades de Atenção Primária à Saúde, no município de Juiz de Fora, em mulheres de 20 a 59 anos, cujo desfecho foi o Excesso de Peso medido por meio do Índice de Massa Corporal. Entre as 2018 mulheres incluídas na análise, a prevalência de Excesso de Peso foi de 61,0%. Na análise multivariada, o Excesso de Peso apresentou associação com as variáveis idade da menarca antes dos 12 anos, ter filhos, idade maior ou igual a 30 anos e relato de hipertensão arterial. A prevalência de excesso de peso em mulheres que tiveram menarca antes dos 12 anos foi 12,4% maior do que naquelas que a tiveram com 12 anos ou mais; enquanto que a prevalência de Excesso de Peso em mulheres que tiveram filhos foi 58,2% maior do que entre as que nunca tiveram. Foi observada elevada prevalência de Excesso de Peso na população feminina adulta, com ênfase na influência dos fatores reprodutivos.

Abstract Overweight stands out as a growing health problem in the population, resulting in individual and societal burdens. This study aimed to identify the association between reproductive factors and overweight in women of reproductive age attended by a Primary Health Care Unit (UAPS).This is a cross-sectional study with home capitation and data collection in two PHC Units, in the city of Juiz de Fora (MG), Brazil, in women aged 20 to 59 years, whose outcome was the overweight measured by the Body Mass Index. The prevalence of overweight was 61.0% among the 2,018 women included in the analysis. In the multivariate analysis, overweight was associated with the variables age at menarche before 12 years of age, having children, age greater than or equal to 30years, and hypertension. The prevalence of overweight in women who had menarche before 12 years of age was 12.4% higher than those who had menarche aged 12 years or more, and the prevalence of overweight in women who had children was 58.2% higher than those who never had any. There was a high prevalence of overweight in the adult female population, emphasizing the influence of reproductive factors.

Early menarche and teenager pregnancy as risk factors for morbid obesity among reproductive-age women: A case-control study

OBJECTIVES: The aim of this study was to evaluate potential risk factors, including non-communicable diseases, for morbid obesity in women between 20 and 49 years of age. METHODS: We performed a case-control study with 110 morbidly obese women and 110 women with adequate weight who were matched by age and with a 1:1 case to control ratio. All women were between 20 to 49 years old and non-menopausal. Possible risk factors were evaluated through a self-report questionnaire assessing socio-demographic, obstetric and gynecological characteristics, presence of non-communicable diseases and habits. Multiple logistic regression was used to estimate the odds ratio with respective confidence intervals. RESULTS: Menarche under 12 years old, teenage pregnancy and lower educational level were shown to be risk factors for morbid obesity among women of reproductive age. Incidences of non-communicable diseases (diabetes, hypertension, dyslipidemia, liver disease, lung disease, thyroid dysfunction, and joint pain) were increased in women with morbid obesity. CONCLUSIONS: Early menarche, teenage pregnancy and low education level are risk factors for the occurrence of morbid obesity in women of reproductive age. Some non-communicable diseases were already more prevalent in women with morbid obesity even before 50 years of age.

Reproductive factors and risk of breast cancer: A Review.

Breast cancer is one of the most common incident cancer and cause of death from cancer in women. It is known that several factors that influence hormonal status (e.g., age at first child birth) or are markers of change in hormonal status (e.g., age at menarche and age at menopause) are associated with the risk of breast cancer. Reproductive factors are known risk factors for breast cancer that probably act early in life. They point toward endogenous estrogens as likely player in the initiation, progression, and promotion of breast cancer. An attempt has been made in this article to review the scientific data published in Indexed journals on the role of reproductive factors in breast cancer.

Reproductive factors and breast cancer: A case-control study in tertiary care hospital of North India.

Background: Clinical, animal, and epidemiological studies have clearly demonstrated that cancer is a hormonally mediated disease and several factors that influence hormonal status or are markers of change in hormonal status have been shown to be associated with the risk of breast cancer. Aims: To identify the association of various reproductive factors with breast cancer. Settings and Design: A hospital-based, matched, case-control study. Materials and Methods: Three hundred and twenty newly diagnosed breast cancer cases and three hundred and twenty normal healthy individuals constituted the study population. The subjects in the control group were matched individually with the cases for their age ± 2 years and socioeconomic status. A pre-tested, semi-structured questionnaire was administered to each individual to collect information on identification data, socio-demographic profile, and reproductive factors. Statistical Analysis Used: The Chi-square test and unpaired t-test were used. The conditional univariate logistic regression analysis (unadjusted odds ratio and confidence intervals) was used to calculate the significance level of each variable followed by multivariate regression analysis. Results and Conclusions: The cases had a lower mean age at menarche, higher age at marriage, higher mean age at last child birth, lower mean duration of breastfeeding, higher number of abortions, late age at menopause, history of oral contraceptive pills, and a family history of breast cancer as compared to the controls. The results of the present study revealed a strong association of reproductive factors with breast cancer in the Indian population.

Factores reproductivos y cáncer de mama: principales hallazgos en américa latina y el mundo / Reproductive factors and breast cancer: principal findings in latin america and the world

La edad temprana de la menarca y tardía de la menopausia, la nuliparidad y la edad tardía de la madre en el primer embarazo se han relacionado con un incremento del riesgo de cáncer de mama (CaMa). Por el contrario, la paridad y el aumento del tiempo en meses de lactancia, en particular la que se ofrece al primer hijo, se han vinculado con un riesgo menor. La hipótesis de que la función ovárica, a través de sus hormonas, desempeña una función importante en el origen del cáncer de mama se ha sustentado en diversos estudios durante mucho tiempo. Aunque la mayor parte de los factores de riesgo relacionados con las características reproductivas es difícil de modificar, incrementar los meses de lactancia y evitar la exposición a los carcinógenos conocidos durante los periodos de desarrollo de la glándula mamaria son medidas para reducir el riesgo de esta enfermedad.

Early age at menarche and late age at menopause, nulliparity, and late age at first pregnancy have been associated with an increased risk of BC. In contrast, parity and the increase in time breastfeeding, particularly during the first child have been associated with a decreased risk. The hypothesis that ovarian function, through their hormones, plays an important role in the etiology of breast cancer has been supported by various studies for a long time. Although most of the risk factors associated with reproductive characteristics are difficult to modify, to increase the breastfeeding time and to avoid exposure to known carcinogens during periods of development of the mammary gland are good strategies to reduce the risk of this disease.

The Association of Reproductive and Menstrual Factors and Colon and Rectal Cancer Risk in Korean Women / 한국역학회지

Recently, there were several epidemiological studies demonstrating that reproductive and menstrual factors are associated with the risk of colorectal cancer in women. A hospital-based case-control study has been conducted to investigate whether the histories of childbearing, menstruation, and breast-feeding are associated with colorectal cancer risk. The cases were consecutively diagnosed, histologically confirmed, incident patients with cancers of the colon and rectum aged 30-79 who were admitted to three tertiary hospitals in Seoul, Korea between March 1995 and August 1997. Controls were selected in the same hospitals as the cases during the same periods. Finally, a total of 151 cases and 110 controls were selected and interviewed on their reproductive and menstrual characteristics using a structured questionnaire. Earlier age at first birth appears to be related with increased risk of colorectal cancer (multivariate relative risk[RR] of colorectal cancer for or = 2.33; 95% confidence interval[CI] 1.1-5.1, p for trend 0.03). Compared with women who experienced menarche at age 16 or older, women whose menarche occurred at age 14 or less appeared at significantly higher risk of rectal cancer(multivariate RR of colorectal cancer for or =16 = 2.26; 95% CI 1.0-3.4, p for trend 0.03). We found no associations for parity, incomplete pregnancies, menopause, use of oral contraceptives, and hormone replacement therapy. These findings suggest that events of reproductive life may have a bearing on female subsequent risk of colon and rectal cancer

The Menstrual, Reproductive, and Lactational Factors and the Risk of Breast Cancer in Korea: A Population Based Case-Control Study / 한국역학회지

This study was conducted to assess the risk of breast cancer by menstrual, reproductive, and lactational factors in Korean women. A total of 210 women living in Seoul aged 30 to 60 with a first diagnosis of breast cancer from 2 teaching hospitals in Seoul, and 249 control subjects, randomly selected from the female pensioners of Korean Medical Insurance Company living in Seoul were interviewed. There was a increasing risk with the decrease of age at menarche, and the adjusted odds ratio(OR) of early menarche(age 14 years or less compared with over 17 years) was 1.61(95% Confidence Interval [CI]: 0.95-2.74). The longer the interval between menarche and regular menstruation, the less risk of breast cancer(OR=0.31, 95% CI: 0.16-0.60). The effect of these menarche factors were more prominent among premenopausal women. The adjusted OR for the second category(25-29 years old) of the age at first pregnancy and the age at the first full term pregnancy, compared to the reference category( 24 years old), were 0.52(95% CI: 0.30-0.92) and 0.58(95% CI: 0.32-1.06), respectively. The late age at the last full term pregnancy had significant protective effect (OR=0.29, 95% CI: 0.10-0.88), and the age itself was important rather than the interval between the first and last full term pregnancy. Factors related to breast feeding(BF) had protective effect consistently. Among parous women, in referent to no BF, women with 1 year of BF had adjusted OR of 0.34(95% CI: 0.17-0.68), while those with 1-3 years of BF had 0.35(95% CI: 0.18-0.67), 3-5 years had 0.29(95% CI: 0.12-0.74), and more than 5 years had 0.06(95% CI: 0.02-0.17). Age at menarche with regular cycle have stronger effect on especially pre-menopausal breast cancer among Korean women. Recent increase in breast cancer incidence in Korea would be explained by delayed age at first pregnancy or delivery, earlier age at menarche and last delivery, and decrease in brest feeding.

Stress Relating Factors of Working Women in a Bank / 대한산업의학회지

We surveyed 343 female bank clerks to find out associations between stress and a variety of factors including general, menstruation and reproductive characteristics of the participants. Unmarried women composed the majority of younger, lower income and lower education groups than married did. They also showed higher. though not significantly higher, scores for psychosocial well being index(PWJ) and the first three items of the stress survey. And married women scored slightly higher only in the fourth item of the stress survey. Among the subgroups of married and unmarried women, many factors contributed to a higher stress score in two or more items of the stress survey; in unmarried women, lower education level, little physical exercise, and large family inhabitants, in contrast married women, higher monthly income and greater working hours were related to higher stress scores. According to the menstruation factors, subgroups with dysmenorrhea or irregular cycle and scanty bleedig volume in unmarried women and subgroups with dysmenorrhea in married women showed higher stress scores in PWI. In married women, the proportion of those who have been pregnant was 77.2% and the proportion of those who have experienced spontaneous abortion was 24.1%. Those who have ever experienced two or more spontaneous abortion showed higher, though not statistically significantly higher. scores for PWI. In conclusion, dysmenorrhea was associated with high stress score in two groups. And the other factors related to higher score of PWJ were different between unmarred and married women, which should be considered in a management plan for mental health promotion.

A Case-Control Study on Risk Factors of Uterine Cervix Cancer in Korea / 예방의학회지

A hospital-based case-control study was carried out to investigate the risk factors of uterine cervical cancer in korea. Information on a wide-range of life-styles, which might be related with uterine cervix cancer, has been routinely collected through a dual application of the self-administered questionnaire and the direct interview by a well-trained nurse at the Department of Gynecology, Seoul National University Hospitals since 1992. The number of cervical cancer cases, histologically confirmed at the hospital, were 284. Included were 939 women as controls, who were free of past history of any malignancies. Adjusted odds ratio and 95% confidence limits were based on the unconditional logistic regression model. The multivariate logistic model was constructed under the consideration of biologic characteristics on the natural history of the malignancy. In the multivariate results, the uterine cervical cancer risk was higher in women of shorter height(P(trend) <0.05), less educated spouse (P(trend) < 0.001), multiple marriages(adjusted OR=2,70,95% C.I. 1.64~4.47), ever had a family history (adjusted OR=2.14., 95 % C.I. l.18~3.89), multiparity (P(trend) < 0.001), and early age at first delivery (P(trend) < 0.001). These results strongly suggest that the uterine cervix cancer might be related to the reproductive factors, and probably with sexual behaviour of both women and men in Korea.

Menstrual and reproductive factors related to the risk of breast cancer in Korea: Ovarian hormone effect on breast cancer

To support the ovarian hormone hypothesis in the etiology of breast cancer, a hospital-based case-control study with community controls was conducted to evaluate the relationship of intervals among menstrual and reproductive events to the risk of breast cancer in Korea. The cases were 190 breast cancer patients, who had been histologically diagnosed at Seoul National University Hospital from Jan. 1, 1993 to Jun. 30, 1994. Included were cancer-free women, who had undertaken the Gynecological examination at the same hospital (n=190). Women recruited for a survey of diabetes prevalence in Yonchon County, adjacent to Seoul City, were taken as a community control group (n=190). Information on menstrual and reproductive factors with other life-styles was collected through a direct interview by the well-trained interviewers. The adjusted odds ratios and the 95% confidence intervals were based on the unconditional logistic regression model. Likelihood ratio test for trend was applied for the ordinal variables. Early age at menarche, late age at natural menopause, late age at first full term pregnancy, and fewer number of full term pregnancies are independently associated with the high risk of breast cancer in Korea. Moreover, the interval between the age at menarche and the age at natural menopause of community controls (29.9+/-6.15 years) was significantly shortened compared to breast cancer cases (34.9+/-4.42 years). Particularly noteworthy was that intervals between the age at menarche and the age at first full term pregnancy of both control groups (9.0+/-3.72 years for hospital controls; 7.2+/-4.04 years for community controls) were significantly shortened compared to breast cancer cases (11.0+/-4.51 years). These findings support the hypothesis that the longer exposure to ovarian hormones during the reproductive years, the higher the risk of breast cancer.
