(Universidade Federal do Pará, 2011-04-11) MENEZES, Aline Beckmann de Castro; BRITO, Regina Célia Souza; http://lattes.cnpq.br/5576436464955236
There is an extended literature about sexual dimorphism in child behavior, including studies regarding atypical gender patterns or gender non-conformity. This study proposal was elaborated upon discussions about the relation between gender and homosexual behavior. However, it was noted the need to broaden the knowledge over child gender differences through different methodologies in the investigation of gender typical behavior and the influence of these differences upon children social relations. There were made three studies. In the first one, the methodologies of observation and interview were compared, in which it was verified that most playful behaviors occurred among children of the same sex and that some were more common for a specific gender. It was also observed that the contend of interviews were culturally influenced. In the second study two structured instruments were applied to measure gender, being found that there are some plays preferred by each sex and that the child usually identify itself and prefer to play with children of the same sex. In the third study the non-verbal behavior of mixed dyads was analyzed using three different protocols. The results indicated differences between sexes regarding behaviors but the communication effort and the rapport was similar. In general, it was found that there are many similarities in the general behavior between sexes, however in deeper analysis it is possible to identify specific patterns of each gender, especially regarding play styles and non-verbal behavior. Finally, the methods used have advantages and disadvantages that must be considered when choosing and combining methodologies for future researches.

(Universidade Federal do Pará, 2016-02) BORGES, Ana Luiza Vilela; FUJIMORI, Elizabeth; KUSCHNIR, Maria Cristina Caetano; CHOFAKIAN, Christiane Borges do Nascimento; MORAES, Ana Júlia Pantoja de; AZEVEDO, George Dantas de; SANTOS, Karine Ferreira dos; VASCONCELLOS, Mauricio Teixeira Leite de
OBJECTIVE: To estimate the prevalence of sexual initiation and contraceptive use at the last sexual intercourse of Brazilian adolescents, according to sociodemographic features. METHODS: The data were obtained from the Study of Cardiovascular Risks in Adolescents (ERICA), a national school-based cross-sectional study. We included 74,589 adolescents from 32 geographic strata (27 capitals and five sets of municipalities with more than 100,000 inhabitants of each of the five macro-regions of the Country). Information on sexual initiation and contraceptive use at the last sexual intercourse (male condom and oral contraceptive pill) has been used. We have estimated prevalence and confidence intervals (95%CI) considering sample weights according to sex, age, type of school, residence status, macro-region and capitals. RESULTS: We observed that 28.1% (95%CI 27.0-29.2) of the adolescents had already initiated sexual life, with higher prevalence among those aged 17 years (56.4%, 95%CI 53.9-58.9), males (33.5%, 95%CI 31.8-35.2), studying at public schools (29.9%, 95%CI 28.5-31.4), and from the Northern region (33.9%, 95%CI 32.3-35.4), mainly from Macapa, Manaus, and Rio Branco. Among those who had started their sexual life, 82.3% (95%CI 81.1-83.4) reported the use of contraceptive methods at the last intercourse, and the prevalence of use was higher among adolescents aged 17 years (85.3%, 95%CI 82.7-87.6), females (85.2%, 95%CI 83.8-86.5) and those living in the Southern region (85.9%, 95%CI 82.9-88.5). Male condom was used by 68.8% (95%CI 66.9-70.7), with no difference by type of school or macro-regions; the contraceptive pill was used by 13.4% (CI95% 12.2-14.6), and more frequently used among women (24.7%, 95%CI 22.5-27,0) and 17-year-old adolescents (20.8%, 95%CI 18.2-23.6) from urban settings(13.7%, 95%CI 12.5-14.9) and from the Southern region (22.6%, 95%CI 19.0-26.8), and less often in the Northern region. CONCLUSIONS: ERICA’s data analysis on sexuality and contraception shows heterogeneities in the prevalence of sexual initiation and use of contraceptive methods among Brazilian adolescents, depending on their age, where they live, and the type of school they study at. Younger adolescents and those living in the Northern region seem to be more vulnerable to the consequences of unprotected sexual intercourses. descriptors: Adolescent. Sexual Behavior. Contraception.

(Universidade Federal do Pará, 2011-05-06) SANTOS, Jorge Luiz Oliveira dos; CANCELA, Cristina Donza; http://lattes.cnpq.br/8393402118322730
The proposal of this Thesis was to investigate the subjective aspects that are related to parenthood among the young parents that belong to the middle class urban population, in the city of Belém, Estate of Pará, who are living or lived through this experience. Due to the theoretical opacity, which is practical as well, the paternity event in young ages, the work shows an centrality of references that identify issues about the pregnancy amongst those Young parents as an exclusive female problem. At the same time, it was discussed in which way this phenomena can be shaped, among other things, in relation with gender and social class, which revealed very heterogeneous paths and profiles. The deconstruction of ideas coming from the common sense about young parenthood, with the support of the ethnographic method, that gives the voice, or better saying, listens to the young male parents and guided by an anthropological look, shows how those actors have been contemporarily constructing their role as protagonists in the parenthood event.

Sexually Transmitted Diseases (STD) are widespread public health concern, majority among adolescents, because they are most susceptible in respect of the sexuality. Early sexual initiation, multiple sex partners, and lack of condom use are considered risk factors and contribute to the increase in the number of STD cases. In order to better understand high-risk sexual behavior among students, a crosssectional study based on a self-answered anonymous questionnaire was conducted in Joaquim Vicente Rondon High School, a public school of Porto Velho city, Brazil. To verify STD's prevalence, samples of blood, urethral and vaginal discharge had been analyzed. A total of 122 students aged 11 to 19 years participated in the study. 84% known what is a STD, 82,8% informed always using condoms during sex, 11,5% didn't make use of condom, and 5,7% selected their sexual partner. To identify STD variety an enzyme-linked immunosorbent assay (ELISA test) and bacterioscopia by method of gram had been applied. 83 blood samples had been analyzed by ELISA test, and 41 smear tests had been stained by method of gramo The incidence to Chlamydia was observed in 65,3% of females, and 34,6% of young men. Gardnerella vaginalis, Candida albicans and Trichomonas vaginalis were more common pathogenic microorganisms found.

Reflexão sobre a homossexualidade como subproduto da evolução do prazer
(2007-04) MENEZES, Aline Beckmann de Castro; BRITO, Regina Célia Souza
Homosexual behavior in animal species has been seen as a challenge to the evolution theory. Although a non-reproductive response, homosexuality persists in the species. Several hypotheses on homosexuality s evolutionary advantages have been proposed by many authors but they all contain contrary aspects, at least when human beings are concerned. Current suggestion states that since homosexuality is not genetically determined, no survival value is required. Homosexual behavior pattern would be an evolutionary byproduct of pleasure as an essential consequence of the sexual act to favor reproduction and to maintain links between partners. Although still a preliminary proposal, the statement pinpoints new trends in interpretation and investigation within the relationship between homosexuality and evolutionism.
