Response: Several prior studies have suggested that religious service attendance is associated with lower rates of divorce. However, many of these studies have been with small samples and have not had rigorous study designs. In addition, most studies have focused on women earlier in life and there has been little research on the effects of religious service attendance on divorce later in life. While divorce rates in the United States in general has been falling, it has in fact been increasing for middle-aged groups, doubling between 1990 and 2010.

In our study we found that among women in mid- to late- life, regular religious service attendance was subsequently associated with 50% lower divorce rates over the following 14 years of the study.

We also found that among those who were widowed, religious service attendance was associated with a 49% increase in the likelihood of remarrying over the 14 years of the study.

Response: Shift work has progressed in response to changes in economic pressure and greater consumer demand for 24-hour services. There are many economic advantages to increased shift work, including higher employment, increased services to customers, and improved trade opportunities. Currently, one in five employees in the U.S. works nonstandard hours in the evening, night, or rotating shifts. However, shift work, especially night shift work, has been associated with a higher risk of chronic diseases, including type 2 diabetes, cardiovascular disease, and several types of cancer.

Compelling evidence has shown that body weight and lifestyle behaviors, such as smoking, diet, and physical activity can influence type 2 diabetes risk. Among shift workers, excess adiposity and increased smoking are frequently and consistently reported, whereas the evidence on physical activity and diet is mixed. Additionally, no previous study has examined the joint associations of rotating night shift work duration and unhealthy lifestyle factors with risk of type 2 diabetes, or evaluated their potential interactions.

Therefore, we prospectively assessed the joint association of rotating night shift work and established type 2 diabetes lifestyle risk factors with risk of type 2 diabetes and quantitatively decomposed the proportions of the joint association to rotating night shift work alone, to lifestyle alone and to their interaction in two large US cohorts.

Response: Prior prospective studies on red and processed meat consumption with risk of breast cancer have produced inconsistent results.

Current meta-analysis of 15 prospective studies shows that women who eat a high amount of processed meat each day may have a higher risk of breast cancer than those who don’t eat or have a low intake in their diet.  Continue reading
