Abstención sexual durante la Cuaresma en Andalucía a lo largo del siglo XX y su impacto en la estacionalidad de los nacimientos
2018
Durante siglos ha permanecido vigente en las poblaciones católicas un precepto religioso que prohibía las relaciones sexuales durante la Cuaresma. Esta interdicción repercutía en una disminución de concepciones y en un repunte tras dicho periodo, ambos difíciles de detectar porque, en poblaciones que no ejercían un control efectivo de la fecundidad, también se registraba un pico de concepciones durante la primavera. En la actualidad este precepto ha desaparecido como consecuencia de un proceso de erosión que no conocemos suficientemente. Con los datos anonimizados de todas las personas nacidas en Andalucía y supervivientes a 1 de enero de 2003 (n=8.397.206), este trabajo pretende determinar…
The Prevalence of sexual abuse in institutions : Results from a representative population-based sample in Germany
2018
The lifetime prevalence of sexual abuse in institutional settings in Germany was examined in a sample representative of the general adult population (N = 2,437). Participants completed a survey on whether they had ever experienced such abuse, its nature (contact, noncontact, forced sexual, intercourse), the type of institution (e.g. school, club), and the relationship of perpetrator to victim (peer, caregiver, staff member). Overall, 3.1% of adult respondents (women: 4.8%, men: 0.8%) reported having experienced some type of sexual abuse in institutions. Adult women reported higher rates of all types than did men, with rates of 3.9% versus 0.8% for contact sexual abuse, 1.2% versus 0.3% for …
Associations between sexual activity and weight status: Findings from the English Longitudinal Study of Ageing.
2019
Objective To investigate the association between weight status and sexual activity in middle-aged and older adults. Methods Cross-sectional analysis on Wave 6 (2012/13) of the English Longitudinal Study of Ageing. Data were from 2,200 men and 2,737 women aged ≥50 years (mean 68.2 years). The explanatory variable was weight status, defined as normal-weight (BMI: ≤24.9), overweight (BMI: 25.0–29.9) or obese (BMI: ≥30) based on objective measurements of height and weight. Outcome variables were any self-reported sexual activity in the last year (yes/no) and, if yes, frequency of sexual intercourse in the last month. Covariates included a range of sociodemographic, lifestyle, and health-related…
The effects of age at menarche and first sexual intercourse on reproductive and behavioural outcomes:A Mendelian randomization study
2020
SummaryThere is substantial variation in the timing of significant reproductive life events such as menarche and first sexual intercourse. Life history theory explains this variation as an adaptive response to the developmental environment. In environments characterized by harsh conditions, adopting a fast life history strategy may increase fitness. In line with this, there is evidence demonstrating that greater childhood adversity is associated with earlier age at menarche. Here we applied Mendelian randomization (MR) methods to investigate whether there is a causal effect of variation in age at menarche and age at first sexual intercourse on outcomes related to reproduction, education and…
Sexual behavior and suicide attempts among adolescents aged 12–15 years from 38 countries: A global perspective
2020
BACKGROUND: The aim was to investigate the relationship between sexual behaviors and suicide attempts by using data from 38 countries from four World Health Organization regions. METHODS: Cross-sectional data from 116,820 adolescents aged 12-15 years participating in the Global School-based Student Health Survey 2009-2016 were analyzed. Data on sexual behaviors were collected: (i) ever having had intercourse; among those who reported having had intercourse, (ii) multiple (≥2) lifetime sexual partners and (iii) condom use in last sexual intercourse and past 12-month suicide attempts were self-reported. Associations were analyzed using multivariable logistic regression. RESULTS: The prevalenc…
Association between cannabis use and sexual behavior among adolescents aged 12-15 years in 21 low- and middle-income countries.
2019
Abstract Aims To investigate the relationship between cannabis use and two sexual behaviors (ever had sex, multiple partners) in a large representative sample of adolescents aged 12–15 years from 21 low- and-middle income countries. Methods Data from 84,867 adolescents aged 12–15 years participating in the Global School-based Student Health Survey were analyzed. Participants reported lifetime frequency of cannabis use (analyzed as 0, 1–2, 3–19 or ≥ 20 times), whether they had ever had sexual intercourse (yes/no) and, if yes, their lifetime number of sexual partners. We used multivariable logistic regression to analyze associations, adjusting for a range of relevant covariates. Results 12.7%…
Adolescent sexual behavior during periods of increase and decrease in the abortion rate.
2009
OBJECTIVE: To study changes in adolescent sexual behavior in periods of increase (1994-2000) and decrease (2001-2007) in the abortion rate. METHODS: School surveys with self-administered questionnaires were carried out annually among eighth graders (mean age 14.8 years) and ninth graders (mean age 15.8 years) (N=286665) in 1996/1997 and 2006/2007. Schools participated biennially. The proportions of respondents reporting noncoital (kissing light petting heavy petting) and coital (ever had sexual intercourse intercourse at least 10 times at least three partners) sexual experience and nonuse of contraception were studied. RESULTS: Among adolescents both coital and noncoital sexual experiences …
Attraction to male pheromones and sexual behaviour show different regulatory mechanisms in female mice.
2004
In rodents, female sexual behaviour is under hormonal control. The attraction females show for male-derived nonvolatile chemicals (pheromones) can be regarded as the first step of this behaviour, but it is unknown whether this attraction is also modulated by sexual steroids. To test this possibility, ovariectomized adult female mice with no experience of chemical signals from adult males were randomly assigned to four groups that received oil (control), progesterone, estradiol (E) or estradiol+progesterone (E+P) injections, respectively. Females were then tested for their attraction to male-soiled bedding and, subsequently, for their proceptive behaviour when confronted to adult males. Fema…
Quality of partnership in patients with erectile dysfunction after sildenafil treatment.
2001
OBJECTIVE A comprehensive investigation on the quality of partnership of male patients with erectile dysfunction (ED) after treatment with sildenafil vs. untreated patients, as perceived by both the patients and their female partners. METHODS This report describes an observational, cross-sectional exploratory study comparing ED patients responsive to sildenafil with ED patients prior to therapy. Assessments included the 'International Index of Erectile Function' (IIEF) and the 'Partnerschaftsfragebogen' (PFB), a partnership questionnaire used in German-speaking countries. The comparability of the two study groups was examined using a stepwise logit model. Significant intergroup differences …
La objeción de conciencia farmacéutica a la píldora postcoital
2003
The article represents a taking of position regarding the matter of the conscience objection towards the morning-after pill (MAP). The MAP is considered like an emergency contraception that the woman can take within the 72 hours from the sexual intercourse. The mechanisms of action of the product can be the following: a. to avoid the ovulation; b. to prevent the fusion between oocyte and sperm after the ovulation; c. to make impossible the implant of the embryo in the uterus. The author questions in the article if the MAP is abortive and, in this case, explicits the fundamental points of the Spanish law about the conscience objection. It is not difficult to ascertain that the MAP acts as co…
