Tuberculosis ups diabetes risk
A recent study suggests that people who have been afflicted with tuberculosis are often affected with diabetes. The prevalence of diabetes in persons with TB is almost double that of the general populace. A survey of 827 respondents registered with Revised National Tuberculosis Control Programme (RNTCP) five centres in Tamil Nadu found that one-fourth of them suffered from diabetes.
“Diabetics who suffer tuberculosis are easily diagnosed for the condition but the reverse is not true. Many persons with TB who become diabetic are unaware of their condition and they do not respond well to TB drugs. When TB relapses, it is a serious threat as these people can transmit the infection,” Dr Vishwanathan said.
“In countries where TB is prevalent, people with diabetes are at three times the risk of acquiring the infectious disease,” he added.
Dr Vishwanathan suggested that all those being treated for TB be screened for diabetes, as early diagnosis will help manage both diseases. “The government has a national programme for control of diseases such as cancer, diabetes, cardiovascular disease and stroke (NPCDS). The RNTCP should be integrated with the NPCDS so that everyone who has TB is also screened for diabetes,” he added.

Pupils with strong hearts and lungs `score better grades`
Having a healthy heart and lungs may be one of the most important factors for middle school students to make good grades in math and reading, a new study has revealed.
“Cardiorespiratory fitness was the only factor that we consistently found to have an impact on both boys’ and girls’ grades on reading and math tests,” said study co-author Trent A. Petrie, PhD, professor of psychology and director of the Center for Sport Psychology at the University of North Texas.
“This provides more evidence that schools need to re-examine any policies that have limited students’ involvement in physical education classes,” Petrie said.
The researchers gathered data at five Texas middle schools from 1,211 students, of whom 54 percent were female with an average age of about 12. Overall, the group was 57 percent white.
While previous studies have found links between being physically fit and improved academic performance, this study also examined several other potential influences, including self-esteem and social support. It also took into account the students’ socio-economic status and their self-reported academic ability, Petrie said.
In addition to cardio respiratory fitness, social support was related to better reading scores among boys, according to the study.
It defined social support as reliable help from family and friends to solve problems or deal with emotions. For girls, having a larger body mass index was the only factor other than cardio respiratory fitness that predicted better reading scores. For boys and girls, cardio respiratory fitness was the only factor related to their performance on the math tests.
“The finding that a larger body mass index for girls was related to better performance on the reading exam may seem counterintuitive, however past studies have found being overweight was not as important for understanding boys and girls performances on tests as was their level of physical fitness,” Petrie said.
From one to five months before the students were to take annual standardized reading and math tests, they answered questions about their level of physical activity, and how they viewed their academic ability, self-esteem and social support.
The findings were presented at the American Psychological Association’s 120th Annual Convention.
