Secular trends in age at menarche in 20th century Mexico: Differences by ethnicity, area of residency, and socioeconomic status.

Objectives: This study aims to assess the secular trend in age at menarche (AAM) in Mexico over the 20th century, and compare the patterns according to area of residence (rural/urban), socioeconomic status (SES), and ethnicity (indigenous/nonindigenous).

Methods: Data on AAM from 24 380 women aged ≥20 years born between 1906 and 1986 were obtained from the Mexican National Health and Nutrition Survey 2006. Birth cohorts were compared to test for a secular trend and differences in mean AAM by area of residence, SES, and ethnicity were evaluated using the Welch test for heterogeneous variances followed by Tamhane T for post hoc comparisons.

Psychosocial barriers associated with organ donation in Mexico.

Introduction: There is a severe shortage of organs for transplantation worldwide, and Mexico has one of the lowest organ donation rates. In this study, we explored the psychosocial barriers that prevent posthumous organ donation by Mexicans.

Body appreciation and attitudes toward menstruation.

Menstruation is an important function of the female body, yet it has rarely been included in research on body image. As women's attitudes toward menstruation are so often negative, this study was designed to examine whether women with positive body image would have more positive attitudes toward menstruation. Seventy-two American women, ages 18-45 years, were recruited online to complete the Body Appreciation Scale (Avalos et al.

Knowledge about cervical cancer prevention and psychosocial barriers to screening among Mexican women.

The objectives of this study were to evaluate: Mexican women's knowledge about cervical cancer prevention; psychosocial barriers to screening; and the relation of both to cervical cancer screening behavior. Three hundred and eighty-four rural and urban women who had achieved a basic or higher educational level were surveyed. Almost 80% of the women had a Pap test but rural women were less likely to have done so.

Ambivalent sexism and attitudes toward women in different stages of reproductive life: a semantic, cross-cultural approach.

College students in southeastern Mexico (n = 185) and the northeastern United States (n = 96) utilized a semantic differential scale to rate subtypes of women: a menstruating woman, a menopausal woman, a pregnant woman, a premenstrual woman, a woman with a hysterectomy, a teenage girl, a woman in love, and a woman with a young baby. Americans reported significantly more negative attitudes than Mexicans did toward a menstruating woman, a premenstrual woman, a teenage girl, and a pregnant woman. Participants chose more positive words to describe a teenage girl, a woman in love, a pregnant woman, and a woman with a young baby, which is suggestive of a pronatal bias.

Mexican beliefs and attitudes toward menopause and menopausal-related symptoms.

The objective of this study was to explore the beliefs and attitudes toward menopause among young and middle-aged Mexican women and men, as well as the menopausal-related symptoms that middle-aged women report or expect and that other participants think a menopausal woman experiences. The beliefs about and attitudes toward Menopause Questionnaire and the Greene Climacteric Scale were answered by 395 Mexicans between the ages of 20 and 60 years. Comparing middle-aged participants, the most negative attitudes toward menopause were held by surgically menopausal women, and the most positive attitudes by naturally postmenopausal women.

Psychological meaning of a woman with a hysterectomy among Mexican physicians and women.

The psychological meaning of women who have had a hysterectomy, and attitudes toward them, were explored in 121 Mexican gynecologists, 155 women who had undergone a hysterectomy, and 115 women who had not had a hysterectomy. The surveys were completed between January and May 2011. Both groups of women defined a woman who had had a hysterectomy using words with positive meanings (healthy, happy, reassured, and complete), as well as words with negative meanings (sad, incomplete, and irritable).

Menstrual socialization, beliefs, and attitudes concerning menstruation in rural and urban Mexican women.

Women living in rural and urban areas of Mexico answered a questionnaire about what they were told at home about menstruation before their menarche (first menstruation), and answered the Beliefs About and Attitudes Toward Menstruation Questionnaire. Around half of both urban and rural women were told that they were going to experience negative perimenstrual changes. There were fewer urban than rural women who were advised to do or not to do certain activities while menstruating.

Premenarcheal Mexican girls' and their teachers' perceptions of preparation students receive about menstruation at school.

This survey explored how fifth-grade Mexican premenarcheal girls (N = 80) and their teachers (N = 16) view the preparation students receive about menstruation at school. The most discussed topics in class included hygiene and body functions. The main discrepancies between girls and teachers were as follows: (a) more teachers than girls reported that they discussed the emotional aspects of menses, (b) teachers indicated that their pupils were better prepared than the students themselves believed.

[Validation of a scale measuring coping with extreme risks].

Objective: The objective of this study was to validate, in Mexico, the French coping scale "Echelle Toulousaine de Coping".

Material And Methods: In the fall of 2001, the scale questionnaire was applied to 209 subjects living in different areas of Mexico, exposed to five different types of extreme natural or industrial risks. The discriminatory capacity of the items, as well as the factorial structure and internal consistency of the scale, were analyzed using Mann-Whitney's U test, principal components factorial analysis, and Cronbach's alpha.

Menstrual-related changes expected by premenarcheal girls living in rural and urban areas of Mexico.

Most women experience changes surrounding the start of menstruation. These changes are influenced by sociocultural context. Consequently, certain changes are more pronounced in some cultures than in others.
