A marriage trichotomy and its applications

This paper promotes research methods specific to men, the new focus of fertility and family planning studies (especially in sub-Saharan Africa). I propose a novel marriage categorization based on married men’s intentions to take another wife. The three marriage groups are currently monogamous men who intend to remain so, currently monogamous men who intend to become polygynous, and currently polygynous men. The first analysis demonstrates that typical marriage analyses may misclassify men who intend to become polygynous. Applications of the marriage trichotomy illustrate that men with varying marital intentions have differing desires regarding fertility and family planning.     

Why the rise in adolescent fertility rates in the Dominican Republic in the 1990s?

Despite concern over high pregnancy rates and levels of risk for sexually transmittedinfections, adolescent fertility rates in the Dominican Republic have not changed substantially since the early 1980's, and actually increased during the early to mid 1990s. The present study was undertaken to assess the factors contributing to the recent rise in fertility among Dominican adolescents. The findings suggest that although contraceptive use among adolescents and young adults has increased, this has been more than offset by ominous trends on other determinants of fertility. Among these are declines in mean age at first sex and first marriage/union without a commensurate decline in mean age at first contraceptive use, and stubbornly high discontinuation rates for oral contraceptives andcondoms. There is also some evidence that rates of induced abortion among adolescents may have increased, without which adolescent fertility rates would have been even higher. Demand for children among Dominican adolescents remains strong, suggesting that efforts to reduce the current high prevalence of risky sexual behaviors need to influence social norms in order to be successful.     

Polygyny and African couple research

Fertility and family planning research has recently begun to focus on couples, rather than solely on women. High levels of polygyny in sub-Saharan Africa create two interesting problems for couple analyses. First, some men match with multiple wives in a given sample. Hence observations of a dependent variable that are a function of the responses from a polygynous man are not statistically independent. To correct for this, we propose that researchers use the method of generalized estimating equations. The second problem occurs when survey questions do not properly account for men having multiple partners. Variables constructed from such questions may contain error. Until better data are available, we propose that researchers randomly select a wife for each polygynous man to reduce the effects of this error. We illustrate these ideas by studying the determinants of couples having innovative family planning behaviors and attitudes in Niger.     

Quality, accessibility, and contraceptive use in rural tanzania

We examine how informants' reports on community perceptions of the quality and accessibility of family planning facilities relate to the use of modern contraceptives by individuals in rural Tanzania. Using information on individual-level contraceptive use in conjunction with community-level information on the accessibility and quality of family planning facilities, we employ two distinct statistical procedures to illustrate the impacts of accessibility and quality on contraceptive use. Both procedures treat the community-level variables as imperfect indicators of characteristics of the facilities, and they yield nearly identical implications. We find that a community-level, subjective perception of a family planning facility's quality has a significant impact on community members' contraceptive use whereas other community measures such as time, distance, and subjective perception of accessibility have trivial and insignificant direct impacts, net of the control variables. Future research that uncovers the determinants of perceptions of both community-level and individual-level quality could provide key insights for developing effective and efficient family planning programs.
