The effects of phenylpropanolamine on dietary intake, physical activity, and body weight after smoking cessation.

This investigation evaluated the effect of phenylpropanolamine on the weight gain associated with 2 weeks of abstinence from smoking. Subjects were 57 adult female cigarette smokers who were randomly assigned, in a double-blind procedure, to chew gum with phenylpropanolamine or placebo gum, or to chew no gum. After a baseline assessment, subjects were paid to quit smoking for a period of 2 weeks. Forty-one (72%) of the 57 subjects were successful in quitting smoking for the 2-week period. Results indicated that, relative to the other two conditions, abstinent subjects receiving phenylpropanolamine gained 1.5 to 1.9 pounds less weight (p less than 0.05). In addition, abstinence rates were higher (p less than 0.03) and dietary intake lower for subjects receiving phenylpropanolamine (p less than 0.05) relative to the other two conditions. No changes in physical activity were observed. It is concluded that phenylpropanolamine may help reduce weight gain associated with smoking abstinence and in this way may enhance smoking cessation efforts in certain individuals.

The effects of applicant's health status and qualifications on simulated hiring decisions.

The effects of having diabetes or obesity on simulated job decisions was evaluated in a two (qualifications, high v. marginal) by three (diabetes, mildly obese, or normal) design. Subjects were 295 adults, averaging 5.02 years of full-time employment in white-collar settings, recruited in advanced level graduate or undergraduate business classes. Each subject examined a job description and a resume of the 'applicant' and viewed a 5-minute videotape. The applicant's face was never seen and an off-camera voice, constant across all conditions, was dubbed in for the applicant's responses to the interviewer's questions. Subjects were then asked to rate the applicant's qualification level and demeanor during the interview and to recommend whether or not to hire the individual. Subjects were also asked to make ratings about the applicant's work habits, work reliability and absenteeism, and interpersonal skills (e.g. emotional problems, likeability). Results indicated that level of quantification affected decisions to hire the applicant in the predicted direction. However, the obese applicant was rated as less qualified for the job, and both the diabetic and obese applicant were less likely to be hired, although they were rated similarly on personal appearance, attitude during the interview, and communication skills. Additionally, both the obese and the diabetic applicant were viewed as having poorer work habits. The diabetic was rated as much more likely to have medically-related job absences, whereas the obese applicant was rated as more likely to have other absences (e.g. abusing company privileges by feigning illness) and to have emotional and interpersonal problems.(ABSTRACT TRUNCATED AT 250 WORDS)

Effects of dietary restraint, obesity, and gender on holiday eating behavior and weight gain.

This investigation evaluated the impact of dietary restraint, relative weight, and gender on holiday eating behavior and weight gain. 65 Ss (31 men and 34 women) completed detailed food records for the 2 days before, the 4 days during, and the 2 days after the Thanksgiving weekend. Results indicated increased eating during the Thanksgiving holiday, with men eating more than women and the obese eating less than the nonobese. There was also a significant Total Restraint X Weight X Time interaction, with unrestrained normal-weight subjects behaving similarly to high-restrained overweight subjects over time. There was also a highly reliable Total Restraint X Sex X Time interaction. The most striking finding from this interaction was that high-restrained women displayed decreases in their dietary intake over time. Correlational analyses revealed that restraint scores were negatively associated with dietary intake over the 8-day period but were positively associated with weight gain. The implications for dieting, eating behavior, and energy balance are discussed.

Accuracy of self-reports of food intake in obese and normal-weight individuals: effects of obesity on self-reports of dietary intake in adult females.

The purpose of this study was to determine the accuracy of self-reported 24-h dietary recalls of overweight and normal-weight adults. Forty female college students (21 overweight, 19 normal weight) consumed a lunch meal at the university cafeteria while being unobtrusively observed. The following day subjects returned to the lab and completed a 24-h recall of their food intake. Accuracy of recalls was assessed by comparing directly observed intake with self-reported intake. Correlated t tests comparing observed and reported intake found a significant amount of overreporting of consumption for the entire sample. When analyses were conducted on individual groups (normal weight vs overweight), no between-group differences were found. A series of one-way analyses of variance (ANOVA) (normal weight vs overweight) and a multivariate ANOVA were performed for total calories, nutrients, and the amount of over- and underreporting. No significant differences between groups were observed.
