Eating disturbances in women of color: an exploratory study of contextual factors in the development of disordered eating in Mexican American women.

The relationship between ethnocultural identity, eating practices, and cultural expectations is complex. When there are conflicting cultural demands, eating disturbances can occur. These disturbances affect many aspects of a woman's life, including her quality of life, health, relationships, and academic/career success. Contextual variables that may influence eating disorders in women of color include (a) level of acculturation, (b) socioeconomic status (SES), (c) peer socialization, (d) family structure, and (e) immigration status. This study examined these variables in a college sample of 115 Mexican American women. Each completed a demographic questionnaire and standardized instruments to measure acculturation, eating disorder symptoms, and family issues. Multiple regression analysis indicated that family rigidity contributes to an increased susceptibility for bulimic symptoms (p < .0001). Poor peer socialization and family rigidity were related to the preoccupation with body size and slimness, thus placing young Mexican American women at greater risk for developing self-destructive eating patterns such as severe weight control and dieting behaviors (p < .0001). Implications for health, quality of life, and appropriate therapeutic care are discussed.

A granny-style slip knot for use in eye surgery.

An adjustable knot for use in ocular surgery is described herein. The first part of the knot is a granny knot, which allows tension to be adjusted. The advantages of this knot are: 1) ease of tying; 2) adjustability; and 3) small size of the knot.

Simultaneous and sequential selective suture removal to reduce astigmatism after penetrating keratoplasty.

We studied two separate groups of consecutive eyes with penetrating keratoplasty in avascular corneas in which we performed selective interrupted suture removal to decrease postoperative astigmatism, describing the time course of change in astigmatism. In the first group (29 eyes), multiple interrupted sutures were selectively removed at a single visit in an attempt to reduce the astigmatism to less than or equal to 3 diopters; the patients were followed for 30 months. In the second group (24 eyes), one interrupted suture was removed at each visit every 2 weeks until the astigmatism was less than or equal to 3 D; the patients were followed for 15 months. Surgical techniques were different in the two groups. Both techniques reduced postoperative astigmatism. Larger changes in astigmatism occurred between the first suture removal visit and the subsequent visit in the first group. At 1 year, the multiple-suture-removal-at-a-single-visit group averaged 3.1 D of astigmatism, with 50% of eyes less than or equal to 3 D, whereas the single-suture-removal-at-multiple-visits group had a mean astigmatism of 1.9 D with 88% of eyes less than or equal to 3 D. The two groups we studied were not directly comparable, because surgical techniques differed, because they were operated at different times, and because the cases were not randomized. Nevertheless, we think that selective suture removal to reduce astigmatism after penetrating keratoplasty is best done by removing only one (or sometimes two) sutures per examination.
