“…An association between HC use and unhealthy lifestyle, in particular current cigarette smoking, was found in our study as well as in others [11][12][13][14]29]. Clustering of behavioral cardiovascular risk factors among adolescents has been previously observed to be associated with an adverse biological cardiovascular risk profile [13].…”

“…Events such as venous thrombosis, stroke, and myocardial infarction occur rarely in adolescents, thus, hard endpoint studies would require extended follow-up far into adulthood. Previous epidemiological studies on HCs and cardiovascular risk in adolescents focused on behavioral risk factors relevant to cardiovascular risk or surrogate endpoints, such as blood pressure and serum lipids [11][12][13][14][15][16].…”

RESULTSHC users were more likely than nonusers to combine several behavior-related health risks, independent of sociodemographic factors. In particular, HC use was strongly associated with current smoking (odds ratio: 3.4, 95% confidence interval: 2.7-4.3). HC use and behavioral factors showed an additive effect on biological cardiovascular risk factors, explaining between 6% and 30% of the population variance. Relative contributions of HC use ranged from <1% for systolic and diastolic blood pressure to 12% for hs-CRP. CONCLUSIONSHC use among 13-17-year old girls in Germany is significantly correlated with a more unfavorable cardiovascular risk profile, which is partly explained by a clustering of behavioral risk factors among HC users. When prescribing HC to teenagers, physicians should 2 systematically assess avoidable behavioral cardiovascular risk factors and provide counseling tailored to the risk profile of the individual patient.

Oral contraception and cardiovascular risk factors during adolescence

2000

View full text Add to dashboard Cite

The objective of the present study was to analyze the pattern of oral contraceptive (OC) use in teenagers and to examine the relationship between OC use and other cardiovascular risk factors. The study was conducted in 24 Belgian secondary schools. Most students (1526 adolescents aged 12-17 years) agreed to participate (participation rate: 83.6%). Smoking, physical activity habits, menarche, and OC use were assessed by a self-administered questionnaire. Total cholesterol level, blood pressure and anthropometric measurements were also measured. Fourteen per cent of mature girls (14%, n ϭ 92) were OC users. Two-thirds of them (66.3%, n ϭ 61) were taking OC which contained either gestodene or desogestrel. Blood pressure and BMI were similar for OC users and non-users. Total cholesterol level was significantly higher in OC users than in non-users (191 mg/dL versus 172 mg/dL). Logistic regression model confirmed the significant influence of OC use on total cholesterol level (OR ϭ 3.08). OC users were also often smokers (39% versus 20% for non-users). In conclusion, the present study has found significant relationships between OC use and cardiovascular risk factors i.e., high total cholesterol and smoking. The first implication is a need for further research on lipoprotein profile in young OC users. Secondly, the combined use of OC and smoking in teenagers calls for preventive actions.
