    Bone turnover in lactating teenagers: Assessment at the end of pregnancy, during and after the breast feeding period
    (2000) Cattani, A; Zubarew, T; Maddaleno, M; Mosso, L; Lopez, JM; NCD Risk Factor Collaboration (NCD-RisC)
    Background: There is paucity of information about bone metabolism during pregnancy or breast feeding in teenagers. Aim: To study bone turnover at the end of pregnancy and during breast feeding in teenagers and correlate it with environmental, hormonal or nutritional variables. Subjects and methods: Thirty teenagers during their breast feeding period after a first pregnancy and 30 nulliparous girls matched for age, age of menarche and body mass index were assessed three weeks after delivery (period 1), at six months of breast feeding (period 2) and one year after the lactating period (period 3). Calcium intake and plasma calcium, phosphorus, alkaline phosphatases, parathormone, estradiol and prolactin were measured. Calcium, creatinine and hydroxypyroline were also measured in a morning urine samples. Results: Lactating and control girls were aged 16.3+/-0.8 and 16.1+/-0.7 years old respectively. Calcium intake in lactating and control girls was 798+/-421 and 640+/-346 g/day respectively in period 1, 612+/-352 and 592+/-309 mg/day in period 2 and 495+/-180 and 456+/-157 g/day in period 3. During periods 1 and 2, lactating girls had higher alkaline phosphatases (161+/-37 compared to 119+/-28 U/l and 149+/-37 compared to 106+/-23 U/l), parathormone (4.3+/-2.6 compared to 2/8+/-0.8 ng/dl and 3.6+/-1.6 compared to 3.0+/-0.9 ng/dl) and urinary hydroxyproline (95+/-16 compared to 63+/-15 mg/g creatinine and 84+/-19 compared to 59+/-15 mg/g creatinine). No differences were observed in period 3. No correlation between bone turnover variables, body mass index or hormonal parameters, was observed. Conclusions: In teenagers, there is an increase in bone turnover at the end of pregnancy, that persists during the lactating period. These changes are not relaxed to nutritional or hormonal variables.

    French adolescent attitudes towards informal care for physical and emotional or relational problems
    (TAYLOR & FRANCIS AS, 2002) Pommier, J; Billot, L; Mouchtouris, A; Deschamps, JP; Romero, MI; Zubarew, T
    The objective of this study was to determine adolescents' attitudes concerning the use of self-care and traditional medicines. A self-administered anonymous questionnaire with open-ended questions was completed by 543 adolescents aged 15-19 y. The results showed that the most frequent self-care activity for general health problems, in more than three-quarters of them. was self-medication: 14% of them resorted to minor home treatment such as taking care of wounds. handaging or massages. Instructions for use were mentioned by 69% of adolescents as a way of choosing self-prescribed drugs. Natural medicines were used by 32% of the girls and 23% of the boys. mainly herbal teas or plant-based medicines, followed by homoeopathy. Self-care for emotional and relational problems mainly involved thinking about the problem and questioning themselves about their own behaviour or about the way them are. They also mentioned activities Such as sports, going out, listening to music, watching television. and trying to think about something else by keeping themselves occupied. Natural medicines were used by 19% of the girls and 13% of the boys. Plant-based medicines or herbal teas were used most often. followed by drugs or alcohol. with homoeopathy in third place.
