Clinical Trials as Topic↗

Menstrual pattern changes following laparoscopic sterilization: a comparative study of electrocoagulation and the tubal ring in 1,025 cases.

This investigation compared the effects of the laparoscopic occlusive techniques of unipolar electrocoagulation and the tubal ring on subsequent menstrual patterns. The question of whether sterilization, in general, causes menstrual pattern changes is also addressed. The 1,025 cases constituted a data set collected by investigators at five institutions in five countries. After controlling for prior contraceptive use, the two techniques were compared with respect to menstrual cycle regularity, cycle length, flow duration, amount of flow, dysmenorrhea and intermenstrual bleeding. In this series, approximately 10% to 50% (depending on the menstrual parameter) of the menstrual pattern changes seen within six months following sterilization could be attributed to the discontinuation of the Pill or IUD at the time of sterilization. The majority of the women experienced no menstrual pattern changes following sterilization. There was no statistically significant difference between the two occlusion techniques in terms of the proportion of women who reported changes in any of their menstrual parameters. The theory that sterilization causes menstrual pattern changes rests on the hypothesis that the greater the degree of destruction of the uteroovarian vascular anastomosis (as with unipolar electrocoagulation), the greater the amount of subsequent menstrual pattern disturbance. Our findings suggest that this hypothesis is not valid.

Contraceptive continuation rates in Papua New Guinea.

Family planning records were analyzed for 18 urban and rural clinics throughout Papua New Guinea. From the record cards of 7443 women, contraceptive continuation rates for the first method used were calculated. Continuation rates after one year are 92 per cent with the IUD (intra-uterine device), 41 per cent with oral contraceptives and 54 per cent with injections. Differences associated with age, parity, and rural-versus-urban clinics are discussed. Continuation rates are used to give an estimate of current contraceptive use of less than seven per cent of Papua New Guinea women. Improvement in access to services for rural women is needed, as is better communication in the initial interview with a new acceptor.

The oral contraceptive pill: use, user satisfaction, side effects and fears among Manawatu women.

The 1978 Manawatu Family Growth Study included questions on the oral contraceptive pill to gauge aspects of its use, user satisfaction and the experience of side effects and fears. Of the 1390 women aged 16-44 interviewed, 1085 (78 percent) had ever used the pill--411 and 674 were current and previous users, respectively. Among the current users 45.2 percent stated they sometimes forgot to take the pill and 50 percent reported they were not entirely happy about using the pill. For dissatisfied current users and all previous users it was found that: (a) various side effects were experienced by substantial percentages in each group, the most common being weight gain or swelling; and (b) a fear of permanent damage to health was acknowledged by more than half of each group. Concern caused by publicity on side effects was reported by 46.9 percent of those who had ever used the pill. These and other results, and their implications, indicate a need for instruction, guidance and counselling for oral contraceptive users.
