Can expanding access to basic healthcare improve children's health status? Lessons from Indonesia's 'midwife in the village' programme

In the 1990s, the Indonesian government placed over 50,000 midwives in communities throughout the country. We examine how this expansion in health services affected children's height-for-age. To address the problem that midwives were not randomly allocated to communities, the estimation exploits the biology of childhood growth, the timing of the introduction of midwives to communities, and rich longitudinal data. The evidence indicates that the nutritional status of children fully exposed to a midwife during early childhood is significantly better than that of their peers of the same age and cohort in communities without a midwife. The former are also better off than children assessed at the same age from the same communities but who were born before the midwife arrived. Within communities, the improvement in nutritional status across cohorts is greater where midwives were introduced than where they were not. This result is robust to the inclusion of community fixed effects.     

Famine,social disruption,and involuntary fetal loss: Evidence from chinese survey data

Relying on half a million pregnancy histories collected from Chinese women in the late 1980s, we studied nearly a quarter century of self-reported miscarriages and stillbirths in China. Our results suggest that these two forms of involuntary fetal loss are affected not only by biological and demographic factors, such as the mother's age, pregnancy order, and pregnancy history, but also by the mother's social characteristics and the larger social environment. In this article, we focus on how two social and economic crises--the Great Leap Forward famine and the Cultural Revolution--resulted in elevated risks of miscarriage and stillbirth in the Chinese population.     

Sexual behavior and responsiveness to sexual stimuli following laboratory-induced sexual arousal

Sexual excitement can be seen as an action disposition. In this study sexual arousal was expected to generate sexual action and to increase interest and responsiveness to sexual stimuli. In two experiments, male and female participants were exposed to a neutral or a sexual film. We measured genital and subjective responses to the film, and sexual behavior following the laboratory visit. In Experiment 2, film exposure was followed by a task in which participants rated the sexual arousability of neutral and sexual pictures. Rating time of the sexual pictures served as an index for sexual interest. Responsiveness to the sexual pictures was measured by modulation of spinal tendinous (T) reflexes. Sexual activity, but not sexual desire, was higher for participants in the sexual film condition than for participants in the neutral condition. Sexual interest and responsiveness to still pictures were not higher for participants in the sexual film condition than for those in the neutral film condition. In addition, men who saw the neutral film showed a greater responsiveness to still pictures than men who saw the sexual film. The results support the view of sexual arousal as an emotional state generating action tendencies and actual sexual behavior.     

Sexual assault prevention with college-aged women: a bibliotherapy approach

The present research evaluated the efficacy of a skills-based bibliotherapy approach to sexual assault prevention for college-aged women. One hundred and ten participants were followed prospectively for 16 weeks. A self-help book, written by the authors, was compared to a wait-list control on several self-report measures. Results revealed significant differences between groups, with bibliotherapy participants reporting decreased participation in risky dating behaviors and improvement in sexual communication strategies across a variety of dating situations. However, results suggested that the self-help book was no more effective than the wait-list control in reducing rates of sexual victimization. Limitations of the study and directions for future sexual assault prevention research with women are discussed.     

The effects of health and environment on exercise-class participation in older, urban women

This research investigated the effects of health and environmental factors on the dropout and intermittent nonattendance of an exercise program designed specifically for older, female, primary-care patients living in the inner city. Class-attendance records (n = 21,538) from a cohort 110 women were analyzed. Women who dropped out early had poorer perceived health and were more likely to report pain as an exercise barrier at baseline. Those who lived in a census tract where a larger percentage of workers walk to work were less likely to drop out early. Intermittent nonattendance was associated with adverse weather conditions including heat index above 90 degrees F, wind-chill index below 20 degrees F, overcast sky, and snow. Better attendance was associated with greater atmospheric pressure, as well as lower number of sunlight hours per day. This research highlights the need to better understand environmental barriers when promoting physical activities in older women.

Intercourse debut age: poor resources, problem behavior, or romantic appeal? a population-based longitudinal study

The most important predictors of early intercourse debut are reported to be poor social resources and early developing problem behaviors. In this study we have a new, additional emphasis on variables related to self-concept and social acceptance. In a population-based longitudinal study, 1399 Norwegians were followed over a 7-year span. We analyzed data using multivariate Cox-regression techniques. Early intercourse debut was part of a broader spectrum of problem behaviors, including early alcohol intoxication and early-developing conduct problems. A new finding was that a positive self-concept in the domain of romantic appeal was also a strong predictor, but only for boys. We suggest that the findings may have important implications for prevention and more research should be conducted along this line.     

Priming the sexual system: implicit versus explicit activation

We investigated implicit versus explicit activation of the sexual system using a priming paradigm in which sexual slides were preceded by either sexual or neutral primes. In the first experiment, primes were made inaccessible to conscious cognitive elaboration. Identification of sexual targets was facilitated by sexual primes, indicating that sexual representations in memory can be activated automatically. In the second experiment, in which primes were presented at a conscious level, identification of sexual targets was decelerated by sexual primes. Primes elicited subjective sexual arousal in Experiment 2 only, demonstrating that the activation of subjective experience requires conscious cognitive elaboration. With the addition of a sexually specific physiological measure, to be constructed to measure initial genital responses, this paradigm may help elucidate activational mechanisms of sexual response.
