Summer sun exposure: knowledge, attitudes, and behaviors of Midwest adolescents.

BACKGROUND: Extensive print, radio, and television coverage about the dangers of sun exposure and benefits of sun protection occurred over the past decade. Illinois teen knowledge and attitudes about sun exposure/protection, sun-exposure/protection behavior, and information sources were determined by a summer telephone survey. METHODS: Telephone interviews with 658 teenagers between ages 11 and 19 included African-American, Asian, Hispanic, Native American, and white teenagers. RESULTS: Teens knew that too much sun was harmful as it caused skin cancer and sunburn. Sunburn was mentioned more often by those with skin types that burned easily and tanned poorly (I,II) (P < 0.001), was better known to girls than to boys (P < 0.001), and was recognized more by those with higher socioeconomic status (P < 0.001) but was not associated with age. Widely held sun exposure attitudes were socializing with friends and feeling better when outdoors. On weekdays, boys averaged 5.3 hr (SD, 1.65 hr) outside compared with 3.9 hr (SD, 0.75 hr) for girls (P < 0.001). Teenage boys were more likely to obtain occupational sun exposure, and girls sunbathed. Subjects with skin types I and II reported an average of 3.3 sunburns in the past year. During unprotected sun exposure, extensive numbers of teens with moderate-risk skin type experienced at least 1 sunburn per year. Indoor tanning use was more prevalent among older girls and those with skin types I and II. Sunscreen use was associated with water recreational activities (swimming, water sports, and going to the beach) by girls slightly more than by boys (P < 0.001). Hat-wearing was more common among boys than among girls. CONCLUSIONS: Teen knowledge that excessive sun exposure causes skin cancer and sunburns and that wearing sunscreens and hats were sun-protective methods did not enable sun protection that prevented burning. This is particularly troublesome because severe sunburns in youth are associated with an increased risk of melanoma. Existing teen sunscreen use could be broadened by educating teens to use adequate quantities of sunscreen prior to daily sun exposure to prevent painful burns. Messages to teens that emphasize the short-term consequence of painful sunburns because of inadequate protection during outdoor occupational and non-water-related recreational exposure would increase the relevance of the message and may enable behavioral change. Parents and physicians need to be included in messages that are directed to teens and to become part of their education. Parents could ensure an adequate sunscreen supply for daily use by the family, encourage teens not to deliberately tan, and serve as role models for the use of protective clothing.

The occurrence of a prodrome of generalized anxiety in panic disorder.

Twenty-eight percent of 32 panic disordered patients had a prodrome of generalized anxiety symptoms lasting a median of 5 years before the occurrence of their first panic attack. Patients with a generalized anxiety prodrome were similar to the nonprodrome patients for 55 tested clinical variables, including individual anxiety symptoms, response to treatment, severity of illness, and most aspects of family history. It appears that a prodrome of generalized anxiety symptoms is a variation of the presentation of panic disorder. Initially, these patients may be misdiagnosed as having generalized anxiety disorder (GAD) and contribute to the heterogeneity of GAD.

Examination of comorbid anxiety in psychiatric inpatients.

Seventy-three percent of 90 psychiatric inpatients had a coexisting anxiety disorder. There were few differences between patients with or without coexisting anxiety on more than 100 clinical and demographic variables that were tested. Patients who had an anxiety syndrome before the onset of their major psychiatric disorder also showed few differences when compared with patients whose anxiety started coincident to or after another DSM-III axis I disorder. The concept of primary/secondary anxiety disorder may not be useful when applied to a cross-section of psychiatric inpatients.

Proposed delusional depression subtypes: preliminary evidence from a retrospective study of phenomenology and treatment course.

An analysis of the phenomenology and treatment course of 52 subjects with delusional depression suggests that there may be various subtypes: bipolar, early-onset unipolar and possibly a late-onset unipolar. The bipolar subgroup tended to relapse in different but always psychotic directions, and was resistant to lithium carbonate treatment alone. Treatment refractoriness, delusional depressive recurrences, and a dementia-like presentation were associated with a small late-onset subgroup. A high rate of delusionally depressive relapses also characterized the early-onset unipolar group, however, patients with single episodes were found only in this subgroup.

Comparison of major depressive patients with a predominantly sad versus anxious mood.

One hundred and seventy-seven patients with major depressive disorder (MDD) experienced a mood disturbance that could be characterized as predominantly sad (55%), anxious (31%) or mixed (14%). Patients that had a predominantly sad mood were more likely to be hypersomnic, anhedonic, younger and seen in an outpatient setting. Predominantly anxious MDD patients were more likely to have been hospitalized, agitated, psychotic, incapacitated, insomnic, and to have had higher post-dexamethasone cortisol levels.

Failure to differentiate bipolar disorder from schizophrenia on measures of neuropsychological function.

30 inpatients diagnosed with schizophrenia were compared to 35 inpatients with bipolar affective disorder, manic type, on a large group of neuropsychological measures. Separate factor analyses were performed on measures of verbal, spatial, and speed variables in order to generate summary scales. Controlling for the effects of age, education, sex, duration of illness, number of previous hospitalizations, and medications at time of testing, there were no significant differences between diagnostic groups on the three factors or on individual test variables. Patients on medication performed more poorly on speed variables than those off medication. These findings call into question the notion of differential patterns of cognitive deficit among psychotic diagnoses.
