Summary
Extradyadic sexual relationships are common in Norway, with factors like age and relationship duration influencing their occurrence. Many participants did not use contraception during these encounters, increasing STI risks.
Area of Science:
- Sociology
- Psychology
- Public Health
Background:
- Extradyadic sexual relationships (ESR) represent a significant aspect of human sexual behavior with implications for relationship satisfaction and public health.
- Understanding the prevalence and correlates of ESR is crucial for developing targeted interventions and public health strategies.
Purpose of the Study:
- To investigate the prevalence of extradyadic sexual relationships (ESR) among a Norwegian population sample.
- To identify background factors associated with engaging in ESR.
- To examine the extent of condom use in extradyadic sexual encounters.
Main Methods:
- A cross-sectional anonymous self-administered questionnaire survey was conducted.
- The study included a random sample of 9,852 Norwegians aged 18-49.
- Data were collected from 3,387 respondents, with a focus on those ever married or cohabiting.
Main Results:
- 29% of men and 23% of women reported lifetime experience with ESR; 16% of men and 11% of women reported ESR during their current relationship.
- Factors predicting ESR included age, relationship duration, number of sexual partners, sexual orientation, and lower self-esteem.
- Approximately 50% of participants reported no contraception use during their most recent extradyadic sexual intercourse.
Conclusions:
- ESR are prevalent in Norway, influenced by demographic and psychosocial factors.
- A significant proportion of individuals engaging in ESR do not use contraception, highlighting potential risks for sexually transmitted infections (STIs).
- Men's extradyadic partners are often casual, while women's are typically known individuals, suggesting different motivations and relationship dynamics.

01:28Amebiasis
Entamoeba histolytica, a protozoan parasite, is responsible for intestinal and extraintestinal amebiasis. Though a significant proportion of infections remain asymptomatic, approximately 50 million individuals annually are estimated to present with clinical disease, resulting in up to 100,000 deaths globally. The disease burden is disproportionately high in regions with lower socioeconomic status, such as parts of India, Africa, Mexico, and Latin America.Etiology and TransmissionThe infective...
01:43Sex Linked Disorders
Like autosomes, sex chromosomes contain a variety of genes necessary for normal body function. When a mutation in one of these genes results in biological deficits, the disorder is considered sex-linked.
01:23Criticisms of the Evolutionary Perspective
In a study where individuals posing as strangers offered compliments and proposed casual sex to students, the responses differed significantly based on gender. Not a single woman accepted the proposal, while 70% of the men agreed. This outcome provides a useful scenario to explore through the lens of evolutionary psychology and social learning theory, highlighting the diverse perspectives on human sexual behaviors.

01:26Sexually Transmitted Infections
Sexually transmitted infections (STIs) are diseases transmitted primarily through unsafe sexual interactions. Bacteria, viruses, or parasites cause them and can result in severe health complications if untreated.ChlamydiaThe bacterium Chlamydia trachomatis is responsible for the disease Chlamydia, the most common STI in the United States. This peculiar pathogen requires human cells to reproduce, residing intracellularly. The initial infection often goes unnoticed because it typically does not...
01:27Horney's Sociocultural Approach
Karen Horney's psychoanalytic theories emphasize the potential for self-realization and the importance of addressing social and cultural, rather than biological, factors in personality development. She challenged traditional Freudian views, particularly Freud's concept of "penis envy," which she argued stemmed from cultural influences rather than inherent biological differences. Horney believed that any sense of inferiority in women was a result of societal conditioning, such as dependence on...
01:29Close Relationships and Culture
Culture shapes how people approach attraction, choose partners, and build long-term relationships. While some preferences in mate selection appear consistent across cultures, such as men valuing physical attractiveness and women emphasizing financial resources, cultural contexts influence how these preferences are expressed and prioritized. Marriage extends beyond romantic ideals in many societies and is deeply embedded in social, economic, and religious frameworks.The Role of Culture in Mate...
