Long-Term Health Effects on the Next Generation of Ramadan Fasting During Pregnancy

Each year, many pregnant women fast from dawn to sunset during the Islamic holy month of Ramadan. Medical theory suggests that this may have negative long-term health effects on their offspring. Building upon the work of Almond and Mazumder (2008), and using Indonesian crosssectional data, I show that people who were exposed to Ramadan fasting during their mother's pregnancy have a poorer general health and are sick more often than people who were not exposed. This effect is especially pronounced among older people, who, when exposed, also report health problems more often that are indicative of coronary heart problems and type 2 diabetes. The exposed are a bit smaller in body size and weigh less. Among Muslims born during, and in the months after, Ramadan, the share of males is lower, which is most likely to be caused by death before birth. I show that these effects are unlikely to be an artifact of common health shocks, correlated to the occurrence of Ramadan, or o f fasting mainly occurring among women who, irrespective of fasting or not, would have had unhealthier children anyway.health, Ramadan, pregnancy, nutrition, Indonesia

Fasting During Pregnancy and Children's Academic Performance

We consider the effects of daytime fasting by pregnant women during the lunar month of Ramadan on their children's test scores at age seven. Using English register data, we find that scores are .05 to .08 standard deviations lower for Pakistani and Bangladeshi students exposed to Ramadan in early pregnancy. These estimates are downward biased to the extent that Ramadan is not universally observed. We conclude that the effects of prenatal investments on test scores are comparable to many conventional educational interventions but are likely to be more cost effective and less subject to "fade out".

The effect of cigarette taxes during pregnancy on educational outcomes of the next generation

Smoking during pregnancy is most common among women with a low socioeconomic status and is negatively associated with important infant health measures such as birth weight. Cigarette taxes decrease smoking amongst pregnant women, thereby leading to improved birth outcomes. In this paper we investigate whether increasing cigarette taxes can reduce the intergenerational transmission of a low socioeconomic status by reducing smoking rates among pregnant women with low educational attainment. In a first step, we exploit variation in cigarette taxes across U.S. states over time to show that increasing cigarette taxes leads to improvements in the health of newborns which are larger for babies of low educated mothers. In a second step, we look at subsequent educational success of 16-year-olds measured by grade retention and school enrollment in a large sample of adolescents. We find that increasing cigarette taxes improves the outcomes of children from a low socioeconomic background, but find no effects among children from a higher socioeconomic background. Our findings therefore suggest that cigarette taxes can be an effective policy instrument for mitigating the propagation of a low socioeconomic status from one generation to the next

Design for the ASCE steel bridge competition

On April 20, 2013, the Santa Clara University Steel Bridge Team entered in the American Society of Civil Engineers\u27 (ASCE) National Student Steel Bridge Competition. As part of their senior design, the four member team designed and constructed a steel bridge to compete in the annual competition. Engineering senior design projects require thoughtful planning, execution, and documentation throughout the process. The 2013 team approach was to be proactive and aggressive in all aspects of the project. The 2013 Steel Bridge spanned 16.5 ft and had a 3.5 ft cantilever end. The overall dimensions of the bridge for its height and width was 3 ft and 3 ft respectively. The 2013 Steel Bridge Team set design and performance goals for the steel bridge competition. The target build time was 20 minutes, the target weight was 200 lb, the design deflection was 1 inch, and the target placement for display was top 5. The bridge\u27s performance for the competition exceeded all design goals with a build time of 14.75 minutes, bridge weight of 164.8 lb, aggregate deflection of 0.698 inches, and 3 all the design requirements, but also having exceeded goals, the team was very satisfied with the performance of the bridge. The team has moved Santa Clara University dramatically forward in the ASCE Steel Bridge Competition and hopes following teams can continue the legacy

Saving lives at birth:the impact of home births on infant outcomes

Many developed countries have recently experienced sharp increases in home birth rates. This paper investigates the impact of home births on the health of low-risk newborns using data from the Netherlands, the only developed country where home births are widespread. To account for endogeneity in location of birth, we exploit the exogenous variation in distance from a mother's residence to the closest hospital. We find that giving birth in a hospital leads to substantial reductions in newborn mortality. We provide suggestive evidence that proximity to medical technologies may be an important channel contributing to these health gains

Test Characteristics of Urinary Lipoarabinomannan and Predictors of Mortality among Hospitalized HIV-Infected Tuberculosis Suspects in Tanzania.

Tuberculosis is the most common cause of death among patients with HIV infection living in tuberculosis endemic countries, but many cases are not diagnosed pre-mortem. We assessed the test characteristics of urinary lipoarabinomannan (LAM) and predictors of mortality among HIV-associated tuberculosis suspects in Tanzania. We prospectively enrolled hospitalized HIV-infected patients in Dar es Salaam, with ≥2 weeks of cough or fever, or weight loss. Subjects gave 2 mLs of urine to test for LAM using a commercially available ELISA, ≥2 sputum specimens for concentrated AFB smear and solid media culture, and 40 mLs of blood for culture. Among 212 evaluable subjects, 143 (68%) were female; mean age was 36 years; and the median CD4 count 86 cells/mm(3). 69 subjects (33%) had culture confirmation of tuberculosis and 65 (31%) were LAM positive. For 69 cases of sputum or blood culture-confirmed tuberculosis, LAM sensitivity was 65% and specificity 86% compared to 36% and 98% for sputum smear. LAM test characteristics were not different in patients with bacteremia but showed higher sensitivity and lower specificity with decreasing CD4 cell count. Two month mortality was 64 (53%) of 121 with outcomes available. In multivariate analysis there was significant association of mortality with absence of anti-retroviral therapy (p = 0.004) and a trend toward association with a positive urine LAM (p = 0.16). Among culture-negative patients mortality was 9 (75%) of 12 in LAM positive patients and 27 (38%) of 71 in LAM negative patients (p = 0.02). Urine LAM is more sensitive than sputum smear and has utility for the rapid diagnosis of culture-confirmed tuberculosis in this high-risk population. Mortality data raise the possibility that urine LAM may also be a marker for culture-negative tuberculosis

Heterogeneous Effects of Medical Interventions on the Health of Low-Risk Newborns

We investigate the impact of early-life medical interventions on low-risk newborn health. A policy rule in The Netherlands creates large discontinuities in medical treatments at gestational week 37. Using a regression discontinuity design, we find no health benefits from additional treatments for average newborns. However, there is substantial heterogeneity in returns to treatments with significant health benefits for newborns in the lowest income quartile and no benefits in higher income quartiles. This seems due to increased maternal stress from referral to an obstetrician among higher-income mothers, heterogeneous effects of home births, and potential difficulties in risk screening among low-income women
