It is important to note that both pregnancy and oral contraceptive use were included as temporary risk factors in this study.
Since their introduction over 10 years ago, oral contraceptives have gained wide and ever-increasing acceptance as a satisfactory and relatively trouble-free means of fertility control.
It can be seen that the low rate in the oral contraceptive users is not attributable to a deficiency of any particular form of cancer.
While using oral contraceptives this is considered as contraceptive failure.
Our results offer little support to the view that oral contraceptives may protect against disorders of the sebaceous glands.
Of the seven women with this disorder in the present study, only four (the expected number) are in the oral contraceptive group.
Similarly, in 1991, 62% of oral contraceptives were supplied by the private sector compared with 31% in 1984.
With reference to this last point, approximately 60% of women on oral contraceptives are taking an unsuitable preparation.
Their longings and their gratifications depend upon a level of oestrogen which is counteracted by the progestagens in all oral contraceptives.
Thus, this preparation may avoid the thromboembolic risk which has been associated with oestrogen-containing oral contraceptives.
From all the studies mentioned, a reasonable interpretation would be that oral contraceptives present no major teratogenic hazard.
It also appears likely that the increase in risk from oral contraceptives is less than that from prescribed hormonal drugs or pregnancy tests.
A more definite judgment would require a special analysis of the inter-relations between the ethnic factor, the other sociocultural identification variables and the contraceptive data.
Looking first at equation 1, both year of first intercourse and age at first intercourse were positively related to use of contraceptives at first intercourse.
The use of contraceptives was common on the first occasion of intercourse with nearly half of the women relying on the sheath.
