[Contraception and abortion: an update in 2015]. / Contraception et interruption de grossesse.

Family doctors can play an important role in preventing unplanned pregnancies. This article addresses the different contraceptives methods available in Switzerland, which are classified in 2 groups and recommends using the GATHER approach (Greet, Ask, Tell, Help, Explain, Return) to promote compliance. LARC (long acting reversible contraceptives) can be recommended to any woman who needs a reliable birth control method. These contraceptives require minimum effort for high efficiency. Further explanation regarding the use of an emergency contraception must be provided when short action contraceptives are chosen. Switzerland's abortion rate is one of the lowest in the world. Medical abortion tends to be more and more prominent. Under certain circumstances, it can be self-administered at home.

[Dysmenorrhea: a problem for the pediatrician?]. / La dysménorrhée: un problème pour le pédiatre?

UNLABELLED: Dysmenorrhea is common in adolescent years, especially after the onset of ovulatory cycles, usually 2 to 3 years after menarche. Pain and symptoms are responsible for school absenteeism and interruption of sports and social activities. OBJECTIVES: This study aims to measure the prevalence of severe dysmenorrhea and its consequences on adolescent girls in Switzerland. Treatment of dysmenorrhea is discussed and recommendations for clinical practice are given. STUDY DESIGN: Cross sectional survey (SMASH 02) on a nationally representative sample of adolescents (n=7548; 3340 females), aged 16 to 20 years who attended post-mandatory education. A self-administered questionnaire was used to assess the severity of dysmenorrhea and its consequences on daily life pursuit of medical help and medications used. RESULTS: Among 3340 girls, 86.6% suffered from dysmenorrhea-related symptoms: 12.4% described having severe dysmenorrhea and 74.2% moderate dysmenorrhea. Girls with severe dysmenorrhea described heavier consequences on daily activities compared with girls without dysmenorrhea: 47.8% of girls with severe dysmenorrhea reported staying at home and 66.5% declared reducing their sportive activities. Yet, fewer than half have consulted a physician for this complaint and even fewer were treated properly. RECOMMENDATION: The pediatrician has a pivotal role in screening young patients for dysmenorrhea, as well as, educating and effectively treating adolescent girls with menstruation-associated symptoms. Non-steroidal anti-inflammatory drugs are considered the first-line of treatment for dysmenorrhea, and adolescents with symptoms that do not respond to this treatment for 3 menstrual periods should be offered combined oestroprogestative contraception and must be followed up, as non-responders may have an underlying organic pathology. CONCLUSION: Dysmenorrhea is a frequent health problem in adolescent years and adolescent care providers should be able to care for these patients in an efficient way.

["I'll tell you if you ask me"; screening young people for substance use]. / "J'te dis si tu m'demandes" Repérage de la consommation de substances auprès d'adolescents et jeunes adultes.

Substance use among young people is an important issue for educational, social and medical providers. More than 75% young people have had a medical visit in the last 12 months, making primary care settings ideal for screening and early intervention programs. The prevalence of substance misuse was assessed with the DEP-ADO screen test among young patients attending the primary care consultation of Geneva University Hospitals. The screen was well accepted by both patients and providers and only took about 10 minutes to complete. One in five screened positive for problematic substance use, supporting the current guidelines recommending annual screening for substance misuse in adolescent primary care outpatients.

Primary care services provided to adolescents in detention: a cross-sectional study using ICPC-2.

AIM: The aim of this study was to provide a detailed description of the health problems for which primary care services are provided to adolescents in a juvenile detention facility in Europe. METHODS: We reviewed the medical files of all detainees in a juvenile detention centre in Switzerland in 2007. The health problems for which primary care services were provided were coded using the International Classification for Primary Care, version 2. Analysis was descriptive, stratified by gender. RESULTS: A total of 314 adolescents (18% female) aged 11-19 years were included. Most (89%) had a health assessment and 195 (62%) had consultations with a primary care physician; 80% of the latter had a physical health problem, and 60% had a mental health problem. The most commonly managed problems were skin (49.7%), respiratory (23.6%), behavioural (22.6%) and gynaecological problems (females: 23.9%); 13% females (no males) had sexually transmitted infections (STI), and 8.7% were pregnant. Substance abuse was common (tobacco: 64.6%, alcohol: 26.2%, cannabis: 31.3%). CONCLUSION: In addition to health problems known to be more prevalent among young offenders, such as mental health problems and STI, these adolescent detainees required care for a range of common primary care problems. These data should inform the development of comprehensive primary care services in all juvenile detention facilities in Europe.

[Adolescent health: collaborative effort between school health services, medical practitioners and adolescents or specialized clinics]. / Santé des adolescents: te rôle essentiel de la collaboration entre santé scolaire et institutions de soins.

Adolescents have complex health needs, that require consistent answers between the health and education sectors. This article describes the existing structures and collaborations in Geneva, between medical practitioners, specialized clinics and school health. School health doesn't make any routine health screening, but strengthens its role for guidance of adolescents. Priority health activities for school health include protection of victims of abuse, integration of youth living with a chronic condition, and mediation for students with repeated absences. In any of these cases, collaboration between health services and school health services is essential. In the case of drug abuse, collaboration with teachers is necessary.

[Eating disorders prevention: does school have a role to play?]. / La prévention des troubles du comportement alimentaire: l'ecole a-t-elle un rôle a jouer?

Eating disorders are widespread among adolescents in Western Countries. Some prevention programs have been developed. They target knowledge about eating disorders, eating attitudes or behaviour and media literacy and self-esteem. Unfortunately, most eating disorder prevention programs have not demonstrated some efficacy to decrease eating pathology on the long term. An other strategy to prevent eating disorders would be to integrate obesity in the objectives of these programs. These interventions would help to reach a greater number of adolescent and to avoid side effects of both preventive efforts.

Prevalence and dimensions of sexual orientation in Swiss adolescents: a cross-sectional survey of 16 to 20-year-old students.

AIM: Sexual orientation plays an important part in building identity during adolescence. The aim of this study was to describe patterns of sexual orientation, including sexual attraction, fantasies, affiliations and behaviour. METHODS: The study was based on the analysis of data from computerized self-administered questionnaires of a Swiss national survey on the sexual life of 16 to 20-year-old adolescents (n = 2,075 girls and 2,208 boys.). RESULTS: Overall, 95.0% of girls and 96.2% of boys described themselves as predominantly heterosexual; 1.4% of girls and 1.7% of boys as predominantly homosexual or bisexual; and 2.8% of teenagers (girls: 3.6%; boys: 2.1%) were "unsure" of their sexual orientation. The reported prevalence of homosexual attraction (girls: 2.0%; boys: 2.9%) exceeded homosexual fantasies (girls: 0.4%; boys: 0.5%) and affiliations (girls: 0.3%; boys: 0.5%). Among the 4205 respondents, 31 girls (1.5% of girls) and 56 boys (2.5% of boys) reported sexual behaviour (experience or penetrative intercourse) with a person of the same sex. Among 1.5% of girls and 2.5% of boys who reported sexual behaviour with a person of the same sex, 65% of boys and 80% of girls nevertheless considered themselves as heterosexual. CONCLUSION: For a comprehensive understanding of sexual orientation in adolescence a differentiated look at dimensions of sexual orientation is indispensable. This applies to clinical settings, public health and research.

Abortion requests among adolescents in comparison with young adults in a Swiss region (1990-1998).

AIM: To examine the recent evolution of abortion request rates among adolescents and young adults in the Canton of Vaud (Switzerland) and to describe the circumstances of the abortion requests and sociodemographic characteristics by age subgroups and nationality. METHOD: Data for women aged 14 to 24 y living in Vaud were selected from the 12,358 abortion requests from residents aged 14-49 y between 1990 and 1998. RESULTS: Overall, abortion request rates by age were stable over the study period. However, rates for non-Swiss women were two to three times higher than those for Swiss women, at 4.5 [95% confidence interval [CI]: 3.8-5.2] vs 2.4 [95% CI: 2.1-2.7] per 1000 adolescents below the age of 18, 18.1 [95% CI: 17.2-18.9] vs 8.0 [95% CI: 7.1-8.8] per 1000 women aged 18-19 and 30.5 [95% CI: 29.1-32.0] vs 10.2 [95% CI: 9.6-10.8] per 1000 women aged 20-24. The ratio of abortions to live births was greatest for women under 20 y of age. at 1.9, in comparison with the ratio observed among adult women aged 20-24 (at 0.4). The abortion rate per 1000 conceptions >6 wk remained stable; this rate was 590 per 1000 among 14-19-y-olds in 1997. CONCLUSION: The abortion request rate among youths in this Swiss region has not increased between 1990 and 1998. Efforts must be intensified to ensure universal access to family planning services and contraception, especially for young foreign women and adolescents.

[How to improve use of emergency contraception by adolescents?]. / Comment améliorer l'utilisation de la contraception d'urgence par les adolescents?

OBJECTIVES: To give an overview of knowledge on emergency contraception (EC) and its utilization in the adolescent population, and to present the practical guidelines useful for EC prescription. METHODS: Review of the literature on EC and results of a survey on sexual behavior of 16-20-year-olds in Switzerland are used. RESULTS: Both estrogen-progestin and estrogen are used for EC. Condom breakage, lack of compliance in oral contraception and failure in contraceptive use are the main reasons for using EC. Sexually active adolescents are aware of CPC and 20% of girls have used it in Switzerland. However, insufficient information and low quality of services in emergency situation could be important barriers to the use of EC. DISCUSSION: and conclusion. Practical knowledge and information on EC must be disseminated among adolescents and both professional training and development of the quality of services have to provide better access to EC.

Mapping adolescent health and lifestyles in a multi-state country: methodological aspects and first results.

OBJECTIVES: To explore the feasibility of a geographical analysis (mapping) of data from a national adolescent survey. METHODS: Teenagers 15 to 19 years in high school or apprenticeship (N = 5275 boys and 3993 girls) answered a self-administered anonymous questionnaire targeting health and lifestyles. Switzerland was divided in 14 subunits, each one including at least 400 subjects: large cantons were isolated by themselves whereas smaller ones were aggregated taking into account common cultural, geographical and health characteristics. To minimize the impact of sample differences across the cantons, subsamples were weighted according to age, sex, and professional background. For each variable, the discretization of the values in five classes was performed using the threshold approach which maximizes intergroup differences and minimizes the intragroup differences. RESULTS: The analysis suggests different patterns of distribution depending on the type of variable studied: substance use differs mostly between urban and rural cantons, while mental health differs between French and German-speaking cantons. CONCLUSIONS: Whereas most available atlases are derived from population-based data (i.e., mortality rates), this research demonstrates the feasibility of using self-reported data from school-based survey samples. The presentation of data on attractive maps provides a unique opportunity for generating hypotheses as to the causes of differences across cantons in a multi-ethnic, multicultural country.

[Prevention of risky behaviors in adolescence]. / Prévention des conduites à risque à l'adolescence.

A workshop of the French speaking meeting of practical paediatrics was dedicated to the prevention of risk behaviour among adolescents. Concrete and every day issues were discussed through risk taking during the transitional stages of adolescence. Parents and adolescence demand and health needs were debated, such as the absence of demand and expressed needs from the adolescent him/herself. Evaluation of the at risk situation was clarified.

Sports activities related to injuries? A survey among 9-19 year olds in Switzerland.

BACKGROUND: Most data on sports injuries are gathered in clinical settings so that their epidemiology in the general population is not well known. OBJECTIVE: To explore the link between sports injuries with the type and the amount of sports activity and biological factors. METHODS: In 1996, 3,609 in-school adolescents 10-19 years (1,847 girls and 1,762 boys) participated in a regional survey. This included anthropometric measurements and a self administered questionnaire. RESULTS: Altogether 28.2% of girls and 35.9% of boys reported one or more sports injuries during the previous year and 2.1% of girls and 6.5% of boys reported at least one hospitalization due to a sports injury. Using the mean rate of injuries as reference level, some sports are highly related to injury occurrence: body building (relative risk (RR) 1.7, 95% confidence interval (CI) 1.5 to 1.9), skateboarding and rollerskating (RR 1.6, 1.4 to 1.8), athletics (RR 1.5, 1.3 to 1.7), snowboarding (RR 1.5, 1.4 to 1.6), basketball (RR 1.3, 1.2 to 1.4), soccer (RR 1.3, 1.2 to 1.4), and ice hockey (RR 1.2, 1.1 to 1.3). Using a logistic regression, several variables associated with a higher risk of injury were identified: the amount of physical activity, high risk sports, and Tanner pubertal stages. CONCLUSION: The risk of sports injury increases not so much with age but with exposure to specific sports and with pubertal development.

First sexual intercourse and contraception: a cross-sectional survey on the sexuality of 16-20-year-olds in Switzerland.

BACKGROUND: The onset of sexual activity represents an important development stage with positive aspects, such as love, discovery, intimate relationships, plans for the future, but also with fears of pregnancy, of sexually transmitted diseases and of AIDS. OBJECTIVE: To study perceptions, attitudes, and behaviour related to sexual life, AIDS and contraception; to explore the onset of first sexual relationships and the process of choice of a contraceptive method by the adolescents, in order to improve prevention programmes for young people. METHOD: Analysis of data from a Swiss national survey on adolescent sexuality using a computerised self-administered questionnaire, involving 2075 girls and 2208 boys between the ages of 16 and 20. The use of computers helps improve confidentiality, response rates and acceptability since survey questions are limited to the subjects' sexual experience only. RESULTS: The young people's responses emphasised the importance of emotion in sexual relationships, girls choosing intimacy and fidelity while boys attached more importance to physical pleasure. Three out of four respondents have had a sexual experience and one out of two have had penetrative sexual intercourse. The percentages of condom or oral contraception use are high: at first sexual intercourse, 86.5% used one or the other, while 7.4% did not declare any contraceptive method. The percentages are lower when age at first intercourse is below 15 years, when a girl had an older partner (age difference 7 years and more) and when the 1st relationship is a casual one. During their first stable relationship 41.1% of girls and 30.9% of boys say they have changed their contraceptive method from condom to contraceptive pill, 2.4% of girls and 2.9% of boys say they have given up any form of contraception. Among girls, condom use at first sexual intercourse with a new partner decreases in favour of oral contraception between first and last steady relationships (75.6 vs 58.0%, p < 0.05), the decrease being insignificant between the first and last casual relationships (73.5 and 62.2%, n.s.). Among boys the rates of condom use are equal at first intercourse with the first and last partner (steady relationship: 74.1 and 77.2%; causal relationship: 78.3 and 76.2% respectively). CONCLUSION: The use of condoms is high among Swiss adolescents, particularly at first sexual intercourse. By integrating the prevention of sexually transmitted diseases and of unwanted pregnancies, preventive programmes would address adolescents' needs more effectively.

Drinking behaviour among teenagers in Switzerland and correlation with lifestyles.

UNLABELLED: Several criteria (frequency, hazardous use, drunkenness) were used to delineate four distinct groups and to analyse the relations between patterns of alcohol use and other health variables. In the 1993 Swiss Multicentre Adolescent Survey on Health, anonymous self-administered questionnaires were distributed to a national representative sample of in-school 15 to 20-year-old adolescents. Of the respondents, 25% answered a module targeting alcohol use (n = 2359) of whom 13% were totally abstinent, 55.1% were moderate drinkers (< or = 1 drink/week and < 3 times drunk), 21.7% were 'social' drinkers (> 3 times drunk and < twice driven when drunk) and 10.2% were 'problem drinkers' (> twice driven whilst drunk or > 1 drink/day). Differences between problem drinkers and the rest of the sample showed the former as being predominantly boys with an odds ratio (OR) of 6.3, having a higher lifetime prevalence rate of cannabis use (OR = 3.4), never using seat belts (OR = 2.5), having their family/peers more often involved in alcohol consumption (OR = 1.9), being predominantly apprentices (against high school pupils OR = 1.9), having cheated during courses (OR = 1.9), being a member of a gang (OR = 1.7), having stolen in a public area (OR = 1.7) and having considered suicide (OR = 1.8). CONCLUSION: Within the Swiss context, whereas moderate/occasional use of alcohol must be considered as part of an adolescents' development, regular use of alcohol, often associated with drunkenness and driving while drunk, is associated with various health hazards and problems. Preventive strategies should be built accordingly.

Food and nutrient intakes in a group of 11 to 16 year old Swiss teenagers.

Better knowledge of the dietary intake of teenagers is necessary to help health professionals to provide better advice on an individual and data for prevention and health programme. We carried out a dietary survey by 3-day records technique in a group of adolescents living in the Canton of Vaud, Switzerland. Food habits were traditional but rich in refined products and poor in plant food. Mean daily energy intake, which was 8025 kJ for the girls and 9350 kJ for boys, was lower than the recommended dietary allowances, especially for girls. Independently of the gender, breakfast represented 19% of the total daily energy intake, lunch 31% and dinner 29%. Total energy provided by snacks was 23.0% for girls and 20.4% for boys. The percentage of energy supplied by the afternoon snack was 15.8% for the girls and 13.3% for the boys. The source of energy was 14% from protein, 37% from fat and 49% from carbohydrates. A high percentage of adolescents had low micronutrient intakes (vitamins A, E, B1, B6, C, folates and for minerals magnesium, calcium and iron). An increase intake of vegetables and fruit should thus be strongly encouraged; snacking could offer a target vector to improve dietary nutritional quality.

Protective correlates of stages in adolescent substance use: a Swiss National Study.

OBJECTIVE: To identify factors potentially protective against involvement with additional illicit drugs among adolescent users of marijuana. DESIGN AND METHODS: A cross-sectional, secondary analysis of a national data set of Swiss adolescents was performed. The original survey was conducted in 1992-1993 (N= 9268). Stages of substance use were conceptualized as lifetime use of marijuana of three or more times and as use of marijuana and other illicit drugs (opiates, inhalants, cocaine, hallucinogens, or stimulants) more than twice in the past month. Behavioral characteristics associated with level of drug use were examined. Based on the resilience literature, factors potentially protective against progression of drug use were examined in their bivariate relationships and analyzed in a multiple regression model. RESULTS: Almost one quarter of the surveyed adolescents were classified as past or current marijuana users. One in 20 of these adolescents also used other illicit drugs. Prevalence of risk-related behaviors (e.g., antisocial behavior, accidents, suicide attempts) was elevated for marijuana users compared to nonusers and even more elevated for users of marijuana with other illicit drugs. In a multivariate logistic regression model, communicating well with a parent was significantly associated with not having progressed to use of illicit drugs other than marijuana [for males, odds ratio (OR) = 0.72, confidence interval (CI) = 0.55, 0.92; for females, OR = 0.60, CI = 0.39, 0.93]. Other significant protective correlates for boys were academic achievement (OR = 0.66, CI = 0.47, 0.92), type of education: school versus apprenticeship (OR = 0.42, CI = 0.21, 0.87), confiding in a family member (OR = 0.49, CI = 0.28, 0.85), and regular participation in a sports club (OR = 0.39, CI = 0.22, 0.77). CONCLUSION: Within this national sample of Swiss adolescents, a cross-sectional analysis identified the quality of relationships within the family and factors related to school associated with lack of progression of illicit substance use. However, longitudinal studies will be necessary to confirm these associations and to allow for designing interventions targeting the enhancement of protective factors among young people already at risk for serious substance use.

Food habits and sport activity during adolescence: differences between athletic and non-athletic teenagers in Switzerland.

OBJECTIVE: To describe food habits and dietary intakes of athletic and non-athletic adolescents in Switzerland. SETTING: College, high schools and professional centers in the Swiss canton of Vaud. METHOD: A total of 3,540 subjects aged 9-19 y answered a self-reported anonymous questionnaire to assess lifestyles, physical plus sports activity and food habits. Within this sample, a subgroup of 246 subjects aged 11-15 also participated in an in-depth ancillary study including a 3 day dietary record completed by an interview with a dietician. RESULTS: More boys than girls reported engaging in regular sports activities (P<0.001). Adolescent food habits are quite traditional: up to 15 y, most of the respondents have a breakfast and eat at least two hot meals a day, the percentages decreasing thereafter. Snacking is widespread among adolescents (60-80% in the morning, 80-90% in the afternoon). Food habits among athletic adolescents are healthier and also are perceived as such in a higher proportion. Among athletic adolescents, consumption frequency is higher for dairy products and ready to eat (RTE) cereals, for fruit, fruit juices and salad (P<0.05 at least). Thus the athletic adolescent's food brings more micronutrients than the diet of their non-athletic counterparts. Within the subgroup (ancillary study), mean energy intake corresponds to requirements for age/gender group. CONCLUSIONS: Athletic adolescents display healthier food habits than non-athletic adolescents: this result supports the idea that healthy behavior tends to cluster and suggests that prevention programs among this age group should target simultaneously both sports activity and food habits.
