An examination of the rate of high school completion experienced by handicapped and nonhandicapped students in the state of Texas

This research examines the graduation rate experienced by students receiving public education services in the state of Texas. Special attention is paid to that subgroup of Texas students who meet Texas Education Agency criteria for handicapped status. The study is guided by two research questions: What are the high school completion rates experienced by handicapped and nonhandicapped students attending Texas public schools? and What are the predictors of graduation for handicapped and nonhandicapped students?^ In addition, the following hypotheses are explored. Hypothesis 1: Handicapped students attending a Texas public school will experience a lower rate of high school completion than their nonhandicapped counterparts. Hypothesis 2: Handicapped and nonhandicapped students attending school in a Texas public school with a budget above the median budget for Texas public schools will experience a higher rate of high school completion than similar students in Texas public schools with a budget below the median budget. Hypothesis 3: Handicapped and nonhandicapped students attending school in large Texas urban areas will experience a lower rate of high school completion than similar students in Texas public schools in rural areas. Hypothesis 4: Handicapped and nonhandicapped students attending a Texas public school in a county which rates above the state median for food stamps and AFDC recipients will experience a lower rate of high school completion than students living in counties below the median.^ The study will employ extant data from the records of the Texas Education Agency for the 1988-1989 and the 1989-1990 school years, from the Texas Department of Health for the years of 1989 and 1990, and from the 1980 Census.^ The study reveals that nonhandicapped students are graduating with a two year average rate of.906, while handicapped students following an Individualized Educational Program (IEP) achieve a two year average rate of.532, and handicapped students following the regular academic program present a two year average graduation rate of only.371. The presence of other handicapped students, and the school district's average expense per student are found to contribute significantly to the completion rates of handicapped students. Size groupings are used to elucidate the various impacts of these variables on different school districts and different student groups.^ Conclusions and implications are offered regarding the need to reach national consensus on the definition and computation of high school completion for both handicapped and nonhandicapped students, and the need for improved statewide tracking of handicapped completion rates. ^

Folic acid fortification, maternal obesity and neural tube defects: Policy implications

In 1996, the Food and Drug Administration (FDA) mandated that beginning in January 1998, flour and other enriched grain products be fortified with 140 μg of folic acid per 100 g of grain to prevent neural tube defects (NTDs) that occur in approximately 1 in 1,000 pregnancies in the United States (U.S.). Although this program has demonstrated important public health effects, it is argued that current fortification levels may not be enough to prevent all folic acid-preventable NTD cases. This study reviews published literature, on folic acid fortification in the U.S. and countries with mandatory folic acid fortification programs reported after 1992 and through January 2008. Published studies are evaluated to determine if the current level of folic acid fortification in the U.S. is adequate to prevent the most common forms of NTDs (spina bifida and anencephaly), particularly among overweight and obese women. ^ Although consistent improvement in blood folate levels of child bearing age women is reported in almost all studies, the RBC folate concentration has not reached the level associated with the most significant reduction of risk for NTDs (906 nmol/L); approximately half of the potentially preventable NTDs are prevented by fortification at the current U.S. level. Furthermore, the blood folate status of women in higher BMI categories (obese or overweight) has not improved as much as among women in lower BMI categories. Therefore, women classified as overweight or obese have not benefited from the preventive effects of folic acid fortification as much as normal or underweight women. ^ To reduce risk of folate preventable NTDs, especially in overweight and obese women, it may be necessary to increase the current level of folic acid fortification. However, further research is required to determine the optimal levels of fortification to achieve this goal without causing adverse health effects in the general population. ^

Depression care for the old-old in a primary care setting

Objective. Although those age 75 and older are the fastest growing age group in the U.S., few studies focus on the course and treatment of depression in this age group. This study examines the differences between the young-old (age 60 to 74) and the old-old (age 75 and older) in regards to their response to a collaborative care model for depression in primary care. We hypothesized that old-old participants would have more severe depression and have a lower rate of treatment response compared to young-old participants. ^ Methods. The sample consisted of 906 participants (n = 606 young-old; n = 300 old-old) who were randomized to receive the intervention with a depression care manager in the IMPACT trial. This study compared young-old and old-old patients on process of care and outcome variables to identify potential differences between the two age groups. Process of care was determined by the type of treatment and level of stepped care received. Clinical outcomes included SCL-20 depression scores, treatment response (defined as a ≥50% decrease in SCL-20 score from baseline) and complete remission (defined as a SCL-20 score <0.5) at 3-, 6-, and 12-months follow-up. ^ Results. The process of care variables did not differ between the two age groups. SCL-20 depression scores did not significantly differ between the two age groups at all follow-up intervals. Treatment response was significantly different between young-old and old-old participants at 6- and 12-months. Complete remission rates were significantly different between the two age-groups at 12-months follow-up. ^ Conclusions. Young-old and old-old patients have a similar clinical response to initial collaborative depression care in a primary care setting, but old-old patients may have lower rates long-term treatment response and complete remission. These findings will help guide future clinical and public health approaches to treat old-old patients with depression. ^
