RESUMO

BACKGROUND: Advanced practice nursing has emerged as a result of the evolution of healthcare systems, the changing needs of the population and the academic development of nursing, as well as sociodemographic and epidemiological changes. The aim of this study is to describe the professional experiences of Spanish advanced practice nurses in specific positions within the healthcare system in order to better understand the development and characteristics of this specialised nursing role. METHODS: A descriptive qualitative study was conducted. Fourteen advanced practice nurses from healthcare centres participated. Semi-structured interviews were carried out. Braun and Clarke's method for reflexive thematic analysis was followed. The Atlas. Ti version 22 program was used for technological support. The COREQ checklist was used to optimise the reporting of this qualitative study. RESULTS: From the analysis of the data collected, three themes and six subthemes were extracted: 1) Advanced practice nursing on the rise: (a) The driving forces in the development of advanced practice nursing, (b) Barriers to the development of advanced practice nursing; 2) Advanced practice nurses as a response to the population's needs: (a) The development of a new professional nursing role, (b) The patient at the centre of care in advanced practice nursing; 3) Training as the foundation for advanced practice nursing: (a) Expert nurses in a specific context, (b) Differences in the level of training depending on the context. CONCLUSION: Advanced practice nurses have faced countless barriers and difficulties that have impeded them from demonstrating their importance and effectiveness within the healthcare system. A stable regulatory framework for the functions of advanced practice nurses is required to promote care, training and research in the field of advanced practice nursing. Health institutions need to promote the role of advanced practice nurses, facilitate the employment of new professionals, and establish new areas of practice. TRIAL REGISTRATION: Not applicable.

RESUMO

The objective of this research was to analyze the risk of adverse effects in patients older than 65 years with dementia and in concomitant treatment with antidementia and antipsychotic drugs and who are cared for by community nurses. A retrospective cross-sectional descriptive study was carried out. A total of 332 patients who were cared for by primary care teams participated. Most of the patients were women, totally dependent for the basic activities of daily living and residing in the family home. They were polymedicated and there was poor therapeutic adherence. The risk of adverse effects was higher in polymedicated patients who had been taking antipsychotics for longer periods and in those who had a main caregiver. However, those patients who had been assessed by the community nurse were protected from suffering adverse effects. This study demonstrates how integrated and continuous nursing care can reduce adverse effects in this type of patient.

RESUMO

BACKGROUND: Baby-led weaning (BLW) is an alternative method to spoon-feeding to introduce solid foods. This study aimed to describe and understand the experiences and opinions of pediatricians and pediatric nurse specialists of the implementation of the BLW approach. METHODS: An interpretive descriptive qualitative research was carried out. A focus group with 7 participants and 13 face-to-face interviews were conducted between February and May 2022 (17 females and 3 males). All were audio-recorded, transcribed, and analyzed with the supported by Atlas.Ti qualitative data analysis software. RESULTS: From the data, two themes developed: (1) BLW as an ideal method of introducing solid food, with the subthemes: "a natural method of introducing complementary feeding" and "BLW is a safe method"; (2) Perceived barriers to the uptake of the BLW method, with the subthemes: "a lack of BLW training prevents the best practice" and "the influence of family and social context on parents." CONCLUSIONS: Healthcare professionals perceive BLW to be a safe and natural weaning approach. The lack of training of healthcare professionals and the influence of family social context on parents may limit the implementation of BLW. IMPACT: Baby-led weaning is perceived by healthcare professionals as a safe complementary feeding method that promotes chewing, improves growth, and the development of fine motor skills. However, lack of training of healthcare professionals and the family social context of the parents hinders the uptake of baby-led weaning. The views of the family and parents' social context about baby-led weaning may restrict their willingness to use the method. Family education delivered by healthcare professionals may avoid risks and allay parental anxieties about safety.

RESUMO

AIMS: The objective of this study was to describe and understand irregular migrants' (IMs') experiences of health disparities while living in informal settlements (ISs) during the COVID-19 pandemic. DESIGN: Qualitative descriptive study. METHODS: Thirty-four IMs originating from different African countries living in ISs took part in this study. Data were collected between January and March 2022 through three focus groups and 17 in-depth interviews. Thematic analysis was used to analyse qualitative data with ATLAS.ti computer software. RESULTS: Three main themes emerged: (1) Extreme vulnerability: ISs and abuse; (2) Inequality in health treatment has increased during COVID-19; and (3) The impact of COVID-19 on the health of IMs: help from non-governmental organizations and nurses. CONCLUSION: Irregular migrants are at a higher risk of exposure to COVID-19 due to their precarious living conditions, administrative situation and access to the health system. It is recommended that specific programmes be strengthened to improve health care for this population. IMPACT: What problem did the study address? This study examines IMs' experiences of health disparities during the COVID-19 pandemic. What were the main findings? IMs are at higher risk of exposure to COVID-19 due to social, health, housing and work inequalities. Community health nurses alongside non-governmental organizations have facilitated the implementation of measures to protect this population against COVID-19. Where and on whom will the research have an impact? With the aim of improving care for IMs, strategies have been suggested for health institutions to address problems relating to accessing the health system, and to promote networking between non-governmental organizations and community health nurses.

RESUMO

AIM AND OBJECTIVES: The aim of this study was to describe and understand how heterosexual women with Turner Syndrome experience sexuality. BACKGROUND: Turner Syndrome is a genetic condition that is the result of one of the X chromosomes missing or partially missing, and it affects women of all ages. Turner Syndrome may lead to psychological, relational and sex life disorders. DESIGN: This is a qualitative study, and the COREQ checklist was employed to report on the current study. METHODS: The study was conducted in a region of southern Spain. Convenience and snowball sampling were used to recruit 18 women, aged 22-51 years, who had been diagnosed with Turner Syndrome. Participants' experiences were explored through semi-structured interviews between January and May 2021. Thematic analysis was used for data analysis. RESULTS: Three main themes and eight sub-themes emerge from the data analysis: (1) Sexuality linked to corporeality, with the sub-themes: 'Discovering that your body is different', 'Social stigma limits one's sex life' and 'Fear of penetration surpresses sexual desire'. (2) Adapting one's sexuality to Turner Syndrome, with the sub-themes: 'Feeling like a woman' and 'Suffering from and adapting to comorbidities'. (3) When infertility overshadows sexuality, with the sub-themes: 'Prolonging childhood by ignoring sexuality', 'Fertility treatment: always a possibility' and 'Lack of specialised professional knowledge'. CONCLUSION: Heterosexual women with Turner Syndrome suffer from sexual problems, delayed diagnosis and treatment, and lack of information. Unawareness and relational problems may also lead to scarce and late sexual relations, jealousy and a fear of being left. The women with Turner Syndrome refer to little self-exploration or masturbation as well as a fear of penetration. RELEVANCE TO CLINICAL PRACTICE: Understanding the experiences of sexuality in heterosexual women with Turner Syndrome is a challenge for clinical nurses, who could provide quality care to these women in contextualised services.

RESUMO

Yawning is a stereotypical behavior pattern commonly associated with other behaviors such as grooming, sleepiness, and arousal. Several differences in behavioral and neurochemical characteristics have been described in high-yawning (HY) and low-yawning (LY) sublines from Sprague-Dawley (SD) rats that support they had changes in the neural mechanism between sublines. Differences in behavior and neurochemistry observed in yawning sublines could also overlap in processes needed during taste learning, particularly during conditioned taste aversion (CTA) and its latent inhibition. Therefore, the aim of this study was to analyze taste memory differences, after familiarization to novel or highly sweet stimuli, between yawning sublines and compare them with outbred SD rats. First, we evaluated changes in appetitive response during long-term sugar consumption for 14 days. Then, we evaluated the latent inhibition of CTA strength induced by this long pre-exposure, and we also measured aversive memory extinction rate. The results showed that SD rats and the two sublines developed similar CTA for novel sugar and significantly stronger appetitive memory after long-term sugar exposure. However, after 14 days of sugar exposure, HY and LY sublines were unable to develop latent inhibition of CTA after two acquisition trials and had a slower aversive memory extinction rate than outbreed rats. Thus, the inability of the HY and LY sublines to develop latent inhibition of CTA after long-term sugar exposure could be related to the time/context processes involved in long-term appetitive re-learning, and in the strong inbreeding that characterizes the behavioral traits of these sublines, suggesting that inbreeding affects associative learning, particularly after long-term exposure to sweet stimuli which reflects high familiarization.

RESUMO

Food palatability and caloric content are crucial factors in guiding diet choice and amount consumed; as a result, sweet caloric tastes are associated with a positive hedonic value. Recent evidence in rodents indicates that consumption of artificial (non-caloric) sweeteners, in which sweet taste is dissociated from normal caloric consequences, could induce changes in energy and body weight regulation, suggesting that sweeteners not only modify intake and appetitive behavior, but could also change taste-learning processes. Particularly, there are different properties in some artificial sweeteners, like saccharin, that might differ from sugar in the reward responses that, after long-term consumption, could also be associated with the inability to learn new negative consequences related to the same taste. Thus, the main goal of this study was to determine, in adult rats, the effects of long-term consumption (14 days) of sugar or saccharin, on taste preference, on new aversive learning, i.e. latent inhibition (LI) of conditioned taste aversion (CTA), and appetitive taste re-learning after aversive taste associations. The results showed that 14 days' exposure to sugar, but not to saccharin, induced a significant increment in the LI of CTA and that taste preference is rapidly recovered during the next 3 days (e.g. CTA extinctions), indicating that long-term sugar consumption significantly accelerates aversive memory extinction during appetitive re-learning of a specific sweet taste; furthermore, high familiarization to sugar, but not to saccharin, promotes appetitive learning for the same taste. Overall, the results indicate that long-term consumption of sugar, but not saccharin, produces changes in appetitive re-learning and suggests that long-term sugar consumption could trigger escalating consumption due to the inability to learn new negative consequences associated with the same taste.

RESUMO

Nowadays, alternative options to conventional wastewater treatment should be studied due to rising concerns emerged by the presence of pharmaceuticals compounds (PhCs) in the aquatic environment. In this work, a combined system including biological treatment by activated sludge plus adsorption with activated carbon is proposed to remove three selected drugs (acetaminophen (ACT), caffeine (CAF) and ibuprofen (IBU)) in a concentration of 2 mg L-1 of each one. For it three sequencing batch reactors (SBR) were operated. SBR-B treated a synthetic wastewater (SWW) without target drugs and SBR-PhC and SBR-PhC + AC operated with SWW doped with the three drugs, adding into SBR-PhC + AC 1.5 g L-1 of a mesoporous granular activated carbon. Results showed that the hybrid system SBR-activated carbon produced an effluent free of PhCs, which in addition had higher quality than that achieved in a conventional activated sludge treatment in terms of lower COD, turbidity and SMP concentrations. On the other hand, five possible routes of removal for target drugs during the biological treatment were studied. Hydrolysis, oxidation and volatilization pathways were negligible after 6 h of reaction time. Adsorption route only was significant for ACT, which was adsorbed completely after 5 h of reaction, while only 1.9% of CAF and 5.6% of IBU were adsorbed. IBU was the least biodegradable compound.

RESUMO

Taste memory recognition is crucial for species survival; thus, the acquisition of conditioned taste aversion (CTA) protects animals against consuming poisons or toxins. In nature, food and poison are confined in the same edible item; however, in the laboratory these food constituents are usually presented separately for experimental analysis. The taste, or conditioned stimulus (CS), can be hours apart from the gastric malaise, or unconditioned stimulus (US); this extended inter-stimulus interval (ISI) allows the analysis of a particular learning phase. Evidence indicates a relevant function of glutamatergic activity in the insular cortex (IC) throughout the ISI. N-methyl-D-aspartate receptors (NMDAR) are crucial during CTA acquisition and retrieval. However, the exact participation of NMDAR in the IC during the ISI has not been demonstrated. Thus, the aim of this work was to evaluate the effects of temporal NMDAR activation during four time frames throughout the ISI of conditioned sugar aversion with bilateral injections of NMDA at a physiological dose (1 µg/µl) in the IC, given (1) immediately before or (2) immediately after sugar presentation, or (3) immediately before or (4) immediately after LiCl i.p. injection. The results showed that NMDAR activation in the IC had a specific ISI effect during CTA acquisition, increasing aversive memory formation and delaying extinction only after CS presentation. Overall, these results demonstrate that NMDAR in the IC have a particular enhancing associative effect after CS and suggest that there is a precise coincidence in neurochemical events in the IC that correlates with the stimulus to be associated and the glutamate NMDAR activity that must be finely tuned in the ISI during CTA acquisition.

RESUMO

Acetylcholine (ACh) is thought to facilitate cortical plasticity during memory formation and its release is regulated by the nucleus basalis magnocellularis (NBM). Questions remain regarding which neuronal circuits and neurotransmitters trigger activation or suppression of cortical cholinergic activity. During novel, but not familiar, taste consumption, there is a significant increase in ACh release in the insular cortex (IC), a highly relevant structure for taste learning. Here, we evaluate how GABA inhibition modulates cholinergic transmission and its involvement during taste novelty processing and familiar taste memory retrieval. Using saccharin as a taste stimulus in a taste preference paradigm, we examined the effects of injecting the GABAA receptor agonist muscimol or the GABAA receptor antagonist bicuculline into the IC or NBM during learning or retrieval of an appetitive taste memory on taste preference in male Sprague Dawley rats. GABAA receptor agonism and antagonism had opposite effects on cortical ACh levels in novel taste presentation versus familiar taste recognition and ACh levels were associated with the propensity to acquire or retrieve a taste memory. These results indicate that the pattern of cortical cholinergic and GABAergic neuroactivity during novel taste exposure is the opposite of that which occurs during familiar taste recognition and these differing neurotransmitter system states may enable different behavioral consequences. Divergences in ACh and GABA levels may produce differential alterations in excitatory and inhibitory neural processes within the cortex during acquisition and retrieval. SIGNIFICANCE STATEMENT: During learning and recall, several brain structures act together. This work demonstrates interactions between cortical cholinergic and GABAergic systems during taste learning and memory retrieval. We found that the neuroactivity pattern during novel taste exposure is opposite that which occurs during familiar taste recognition. GABAA receptors must be inactive during novel tasting to enable new memory formation, but must be active and inhibiting acetylcholine release in the cortex to allow memory retrieval. These findings indicate that GABA inhibition modulates cholinergic transmission and that cholinergic-GABAergic system interactions are important during the transition from novel to familiar memory.

RESUMO

Sweet foods activate the reward system that is essential in processing natural reinforcers. Maturation changes in this system during adolescence are linked to heightened impulsivity and risk-seeking behavior, including the use of drugs like ethanol. This usually starts with the consumption of sugary mixtures. However, the influence of sugar exposure on ethanol consumption remains inconclusive. The present research examines the effect of long-term sugar exposure on sugary ethanol (S-EtOH) preference and net intake, exploring the implications of sex, age, accessor restriction of sugar, and its effect during the transition into adulthood. Wistar rats of both sexes were given 24-hour access to a sugar solution for 21 days during adolescence or adulthood. Subsequently, four preference tests of S-EtOH vs. water were carried out every other day, with or without sugar access between each preference test. Our results demonstrate that continuous acute and long-term sugar access induces a consummatory suppression effect on S-EtOH intake, particularly in adult rats, irrespective of sex. This effect becomes more pronounced with more extended periods of exposure to sugar, leading to a higher prevalence of low consumers. Notably, when sugar access was restricted after high familiarization, the suppression effect in adolescent male rats was reduced. Under these conditions, the rats appeared to be more susceptible to developing a preference for S-EtOH consumption. Furthermore, our longitudinal observations reveal that sugar access or restriction conditions during the transition from adolescence to adulthood play a crucial role in shaping S-EtOH consumption patterns in adulthood.

RESUMO

Conditioned taste aversion (CTA) is a robust associative learning; liquid deprivation during this conditioning allows researchers to obtain readable measures of associative learning. Recent research suggests that thirst could be a crucial motivator that modulates conditioning and memory extinction processes, highlighting the importance of the body's internal state during learning. Furthermore, the histaminergic system is one of the major modulatory systems controlling several behavioral and neurobiological functions, such as feeding, water intake, and nociception. Therefore, this research aimed to assess the effect of H3 histaminergic receptor activation in the insular cortex (IC) during CTA. For this, we conditioned adult male Wistar rats under two regimens: water deprivation and water ad libitum. A classical CTA protocol was used for water deprivation. Before CTA acquisition, 10 µM R-α-methylhistamine (RAMH), an H3 receptor agonist, was injected into the IC. Results showed that RAMH injections decreased CTA in water-deprived rats without affecting the significant aversion conditioning in rats that were given water ad libitum. Moreover, RAMH accelerated the process of aversive memory extinction under ad libitum water conditions. According to our findings, the degree of liquid satiety differentially affected taste-aversive memory formation, and H3 histamine receptors were more involved under water deprivation conditions during acquisition. However, these receptors modulated the strength of aversive conditioning by altering the rate of aversive memory extinction in the absence of deprivation. In conclusion, histaminergic activity in the IC may influence taste memory dynamics through different mechanisms depending on the degree of liquid satiety or deprivation during conditioning.

RESUMO

(1) Gender-based dating violence is common among adolescents. This violence has global repercussions and can have immediate and delayed consequences on health. Also, cases of dating violence and sexual abuse using technology are increasing. The aim of this research is to describe and understand the perceptions and experiences of Spanish university students aged 18 to 22, about gender-based dating violence and its perpetuation through social media. (2) A qualitative descriptive study was used, following the five consolidated criteria for reporting and publishing COREQ qualitative research. (3) The inductive analysis of the data obtained in the focus group session and the individual interviews of the twelve participants was organised into three major themes: the concept of gender violence that Spanish youth have, the education they have received on gender-based violence and whether they consider that social media are a way to exercise this type of violence. (4) Spanish youth have a broad vision of the attitudes and behaviours that make up gender-based dating violence in an affective relationship. The education received at home is of vital importance for young people, but not all receive it. Social media are frequent tools through which many young people perpetuate controlling partner violence and normalise aspects and situations of gender violence, making it necessary to stress them in prevention programs.

RESUMO

Introduction: The COVID-19 pandemic caused an international health emergency situation where nursing took on a fundamental role. The high number of patients in hospital ICUs led to a shift in nurses' working conditions and workload. Objective: The objective of this study was to describe the experiences of nurses who worked in ICUs during the acute phase of the COVID-19 pandemic. Methodology: A qualitative, descriptive study was carried out, with the participation of 21 nurses who worked in the ICU during the pandemic. Data collection took place between May and July 2021 through 21 in-depth interviews. Results: Three main themes emerged: (1) COVID-19 in ICUs: nurses on the frontline. (2) United against adversity: teamwork. (3) New optics of critical care and the nursing profession. COVID-19 was perceived with harshness, and the lack of knowledge about the virus generated confusion, anxiety and fear due to the risk of transmission to family members and relatives. The pandemic marked a shift in the management of human, material and economic resources. Novice nurses learned critical care at an accelerated pace, with significant physical and psychological strain. Expert nurses carried the burden of training new nurses. Although there were tense situations, experiencing these adverse situations as a team led to feelings of increased belonging, togetherness and professional bonding for nurses. While the participants noted an increase in motivation to continue in their profession, they also had a feeling of not having been cared for as they deserve by healthcare institutions.

RESUMO

BACKGROUND: Adolescence is a crucial time in the development of young people's identity, and sexuality is a key issue. Comprehensive sex education provides the knowledge and skills to help adolescents protect their sexual and reproductive health and rights. Policies on sex education in secondary schools are highly influential in the development of quality programmes that support comprehensive sex education. The aim of this study was to explore, describe and understand adolescents' experiences of sex education. METHODS: A qualitative study based on Gadamer's phenomenology was used. Two focus groups and four in-depth interviews were conducted with 12 private school students, followed by inductive data analysis using ATLAS.ti software 9.0. RESULTS: Two main themes were identified in the analysis: (1) sex education is a challenge for secondary schools and (2) student expectations of sex education. CONCLUSION: It is essential for adolescents to have access to comprehensive sex education that is adapted to the different stages of their development, is provided by specialised teachers, and involves their families in the process.

RESUMO

Long-term memory is achieved through a consolidation process where structural and molecular changes integrate information into a stable memory. However, environmental conditions constantly change, and organisms must adapt their behavior by updating their memories, providing dynamic flexibility for adaptive responses. Consequently, novel stimulation/experiences can be integrated during memory retrieval; where consolidated memories are updated by a dynamic process after the appearance of a prediction error or by the exposure to new information, generating edited memories. This review will discuss the neurobiological systems involved in memory updating including recognition memory and emotional memories. In this regard, we will review the salient and emotional experiences that promote the gradual shifting from displeasure to pleasure (or vice versa), leading to hedonic or aversive responses, throughout memory updating. Finally, we will discuss evidence regarding memory updating and its potential clinical implication in drug addiction, phobias, and post-traumatic stress disorder.

RESUMO

Thirst is an essential motivational component that could modulate the strength of conditioning; pioneer studies show that the rats' sexual dimorphism observed in the rate of aversive memory extinction of conditioned taste aversion (CTA) is affected by the state of fluid deprivation. On the other hand, previous evidence suggests that fluid intake volume and temporal context before and during conditioning may influence CTA. Furthermore, although CTA has been demonstrated using various types of stimuli, neural processing and homeostatic regulation of water and nutritional balance may differ depending on the stimulus used and the conditioning stages. Therefore, this study explored the effects of state motivated by thirst and satiation, using saccharin, as a non-caloric sweet stimulus, during CTA and the aversive memory extinction process under similar contextual and temporal conditions. First, we implemented an ad libitum water protocol in male and female adult rats to evaluate saccharin aversive memory formation; we compared this with a traditional CTA with liquid deprivation in the same context and temporal consumption conditions. Furthermore, we evaluated whether liquid satiety affects the acquisition or the aversive memory retrieval differentially. Our results show that the ad libitum liquid regimen allows reliable quantifications of basal water consumption, monitored every hour for more than five days. We observed a reliable CTA, where the magnitude of aversive memory and its extinction is significantly higher in both male and female rats; the strong CTA observed is substantially due to the satiety state during taste aversion memory retrieval. Our data show that although liquid deprivation does not affect CTA acquisition, it does induce weakness in the magnitude of aversive retrieval expression and fast aversive memory extinction, similarly in male and females. Overall, the results indicate that the need to satiate the demand for liquids during retrieval prevails over the conditioned aversion learned, suggesting, that thirst is a source of temporary variables dominating the aversive responses during CTA retrieval.

RESUMO

Adolescents have a greater risk of acquiring sexually transmitted infections (STIs), which is a serious public health problem. Education is an effective strategy to improve adolescent sexual health outcomes. However, Spanish adolescents have a lack of sex education. The aim of this study was to explore the perceptions and opinions of a sample of adolescents regarding sexually transmitted infections (STIs). Photovoice is a research method that uses the search for images of everyday events with the intention of bringing about social change. An exploratory, descriptive design was used with a qualitative approach based on the Photovoice methodology. The sample consisted of 26 high school and baccalaureate students of Almería (Spain) selected through a convenience sample. The age of the participants ranged from 14 to 17 years, with a mean age of 15.31 years. Two main categories were extracted from the data analysis: 'Towards a culture of preventing STIs and promoting healthy sexual practices' and 'Adolescents' needs from their perspective'. In conclusion, numerous changes take place at the biopsychosocial level during adolescence that imply a need to explore their sexuality in depth. A lack of knowledge and a carefree attitude during sexual initiation can increase the risk of developing STIs. The study's adolescents stated that they do not have adequate sex education to acquire sufficient knowledge about sexuality and sexual health, and therefore, request that the traditional format be modified in order to achieve better results.

RESUMO

BACKGROUND: With life expectancy increasing, there is a growing need to train healthcare support workers who provide care for dependent people in healthcare centres and at home. This qualitative study, based on Gadamer's hermeneutic philosophy, aimed to understand the learning experiences of future healthcare support workers currently enrolled in an intermediate, dual modality vocational training programme with regard to caring for dependent people. METHODS: Convenience sampling was used to recruit the participants, who were all students enrolled in an intermediate level vocational training programme in care for dependent people. Fourteen in-depth interviews and one focus group session were conducted with the students. Atlas.ti 8.0 software was used to analyse the participants' accounts. RESULTS: The students highlighted the vocational nature of their studies and the need to feel competent and useful as a healthcare support worker for dependent people. Practice-based learning and the need for training in core competences are complementary and essential elements of the training process. CONCLUSIONS: The participants' previous experiences were key in determining their academic trajectory and reflect their motivation and interest to learn. However, they feel vulnerable, unprotected, and lack training in psychosocial skills. Educational institutions should focus training programmes on the practice and development of psychosocial skills that motivate students to acquire transversal competences.

However, little is known about the factors that have an impact on sexuality in late adolescence. The aim of this study was to explore and describe the perspectives of late adolescents on the factors that influence their sexual lives. (2) Methods: A qualitative study with a descriptive design was carried out. Thirteen interviews were conducted. Data were audio-recorded, transcribed, and categorized into themes and subthemes. (3) Results: The results of our study offer support for the importance of sexual aspects in the lives of late adolescents who identify as heterosexual. (4) Conclusions: The most influential environments in late adolescent sexuality are the social, family, school, and peer contexts.
