We observed a large downward bias in reporting food intake related to social desirability score. These results are consistent with the theoretical constructs on which the hypothesis is based. The effect of social desirability bias is discussed in terms of its influence on epidemiological estimates of effect. Suggestions are made for future work aimed at improving dietary assessment methodologies and adjusting risk estimates for this bias.
This study was designed to determine the effectiveness ofa group stress reduction program based on mindfulness meditation for patients with anxiety disorders. Method: The 22 study participants were screened with a structured clinical interview and found to meet the DSM-IH-R criteria for generalized anxiety disorder or panic disorder with or without agoraphobia. Assessments, including self-ratings and therapists' ratings, were obtained weekly bef ore and during the meditation-based stress reduction and relaxation program and monthly during the 3-month follow-up period. Results: Repeated measures analyses ofvariance documented significant reductions in anxiety and depression scores after treatment for 20 of the subjects-changes that were maintained at follow-up. The number of subjects experiencing panic symptoms was also substantially reduced. A comparison of the study subjects with a group ofnonstudy participants in the program who met the initial screening criteria for entry into the study showed that both groups achieved similiar reductions in anxiety scores on the SCL-90-R and on the Medical Symptom Checklist, suggesting generalizability of the study f indings. Conclusions: A group mindfulness meditation training program can effectively reduce symptoms ofanxiety and panic and can help maintain these reductions in patients with generalized anxiety disorder, panic disorder, or panic disorder with agoraphobia.
BACKGROUND Models are needed for implementing weight management interventions for adolescents through readily accessible venues. This study evaluated the feasibility and efficacy of a school nurse-delivered intervention in improving diet and activity and reducing BMI among overweight and obese adolescents. METHODS Six high schools were randomized to either a 6-session school nurse-delivered counseling intervention utilizing cognitive-behavioral techniques or nurse contact with provision of information. Eighty-four overweight or obese adolescents in grades 9 through 11 completed behavioral and physiological assessments at baseline and 2- and 6-month follow-ups. RESULTS At 2 months, intervention participants ate breakfast on more days/week (difference = 1.01 days; 95% CI 0.11, 1.92), and had a lower intake of total sugar (difference = −45.79g; 95% CI −88.34, −3.24) and added sugar (difference = −51.35g; 95% CI −92.45, −10.26) compared to control participants. At 6 months, they were more likely to drink soda ≤ one time/day (OR 4.10: 95% CI 1.19, 16.93) and eat at fast food restaurants ≤ one time/week (OR 4.62: 95% CI 1.10, 23.76) compared to control participants. There were no significant differences in BMI, activity or caloric intake. CONCLUSION A brief school nurse-delivered intervention was feasible, acceptable, and improved selected obesogenic behaviors, but not BMI.
IMPORTANCE Tobacco use is the leading preventable cause of disease, disability, and death in the US. In 2014, it was estimated that 480 000 deaths annually are attributed to cigarette smoking, including second hand smoke exposure. Smoking during pregnancy can increase the risk of numerous adverse pregnancy outcomes (eg, miscarriage and congenital anomalies) and complications in the offspring (including sudden infant death syndrome and impaired lung function in childhood). In 2019, an estimated 50.6 million US adults (20.8% of the adult population) used tobacco; 14.0% of the US adult population currently smoked cigarettes and 4.5% of the adult population used electronic cigarettes (e-cigarettes). Among pregnant US women who gave birth in 2016, 7.2% reported smoking cigarettes while pregnant.OBJECTIVE To update its 2015 recommendation, the USPSTF commissioned a review to evaluate the benefits and harms of primary care interventions on tobacco use cessation in adults, including pregnant persons.POPULATION This recommendation statement applies to adults 18 years or older, including pregnant persons. EVIDENCE ASSESSMENTThe USPSTF concludes with high certainty that the net benefit of behavioral interventions and US Food and Drug Associated (FDA)-approved pharmacotherapy for tobacco smoking cessation, alone or combined, in nonpregnant adults who smoke is substantial. The USPSTF concludes with high certainty that the net benefit of behavioral interventions for tobacco smoking cessation on perinatal outcomes and smoking cessation in pregnant persons is substantial. The USPSTF concludes that the evidence on pharmacotherapy interventions for tobacco smoking cessation in pregnant persons is insufficient because few studies are available, and the balance of benefits and harms cannot be determined. The USPSTF concludes that the evidence on the use of e-cigarettes for tobacco smoking cessation in adults, including pregnant persons, is insufficient, and the balance of benefits and harms cannot be determined. The USPSTF has identified the lack of well-designed, randomized clinical trials on e-cigarettes that report smoking abstinence or adverse events as a critical gap in the evidence. RECOMMENDATIONSThe USPSTF recommends that clinicians ask all adults about tobacco use, advise them to stop using tobacco, and provide behavioral interventions and FDA-approved pharmacotherapy for cessation to nonpregnant adults who use tobacco. (A recommendation) The USPSTF recommends that clinicians ask all pregnant persons about tobacco use, advise them to stop using tobacco, and provide behavioral interventions for cessation to pregnant persons who use tobacco. (A recommendation) The USPSTF concludes that the current evidence is insufficient to assess the balance of benefits and harms of pharmacotherapy interventions for tobacco cessation in pregnant persons. (I statement) The USPSTF concludes that the current evidence is insufficient to assess the balance of benefits and harms of e-cigarettes for tobacco cessation in adults, including pregnant ...
Once exposure to nicotine had occurred, remarkably few risk factors for smoking consistently contributed to individual differences in susceptibility to the development of dependence or loss of autonomy. An experience of relaxation in response to the first dose of nicotine was the strongest predictor of both dependence and lost autonomy. This association was not explained by trait anxiety or any of the other measured psychosocial factors. These results are discussed in relation to the theory that the process of dependence is initiated by the first dose of nicotine.
US Preventive Services Task Force IMPORTANCE Potentially harmful mutations of the breast cancer susceptibility 1 and 2 genes (BRCA1/2) are associated with increased risk for breast, ovarian, fallopian tube, and peritoneal cancer. For women in the United States, breast cancer is the most common cancer after nonmelanoma skin cancer and the second leading cause of cancer death. In the general population, BRCA1/2 mutations occur in an estimated 1 in 300 to 500 women and account for 5% to 10% of breast cancer cases and 15% of ovarian cancer cases. OBJECTIVE To update the 2013 US Preventive Services Task Force (USPSTF) recommendation on risk assessment, genetic counseling, and genetic testing for BRCA-related cancer. EVIDENCE REVIEW The USPSTF reviewed the evidence on risk assessment, genetic counseling, and genetic testing for potentially harmful BRCA1/2 mutations in asymptomatic women who have never been diagnosed with BRCA-related cancer, as well as those with a previous diagnosis of breast, ovarian, tubal, or peritoneal cancer who have completed treatment and are considered cancer free. In addition, the USPSTF reviewed interventions to reduce the risk for breast, ovarian, tubal, or peritoneal cancer in women with potentially harmful BRCA1/2 mutations, including intensive cancer screening, medications, and risk-reducing surgery. FINDINGS For women whose family or personal history is associated with an increased risk for harmful mutations in the BRCA1/2 genes, or who have an ancestry associated with BRCA1/2 gene mutations, there is adequate evidence that the benefits of risk assessment, genetic counseling, genetic testing, and interventions are moderate. For women whose personal or family history or ancestry is not associated with an increased risk for harmful mutations in the BRCA1/2 genes, there is adequate evidence that the benefits of risk assessment, genetic counseling, genetic testing, and interventions are small to none. Regardless of family or personal history, the USPSTF found adequate evidence that the overall harms of risk assessment, genetic counseling, genetic testing, and interventions are small to moderate. CONCLUSIONS AND RECOMMENDATION The USPSTF recommends that primary care clinicians assess women with a personal or family history of breast, ovarian, tubal, or peritoneal cancer or who have an ancestry associated with BRCA1/2 gene mutations with an appropriate brief familial risk assessment tool. Women with a positive result on the risk assessment tool should receive genetic counseling and, if indicated after counseling, genetic testing. (B recommendation) The USPSTF recommends against routine risk assessment, genetic counseling, or genetic testing for women whose personal or family history or ancestry is not associated with potentially harmful BRCA1/2 gene mutations. (D recommendation)
BACKGROUND Given the dramatic increase in adolescent overweight and obesity, models are needed for implementing weight management treatment through readily accessible venues. We evaluated the acceptability and efficacy of a school-based intervention consisting of school nurse-delivered counseling and an afterschool exercise program in improving diet, activity, and body mass index (BMI) among overweight and obese adolescents. METHODS A pair-matched cluster-randomized controlled school-based trial was conducted in which 8 public high schools were randomized to either a 12-session school nurse-delivered cognitive-behavioral counseling intervention plus school-based after school exercise program, or 12-session nurse contact with weight management information (control). Overweight or obese adolescents (N = 126) completed anthropometric and behavioral assessments at baseline and 8-month follow-up. Main outcome measures included diet, activity, and BMI. Mixed effects regression models were conducted to examine differences at follow-up. RESULTS At follow-up, students in intervention compared with control schools were not different in BMI, percent body fat, and waist circumference. Students reported eating breakfast (adjusted mean difference 0.81 days; 95% confidence interval [CI] 0.11–1.52) on more days/week; there were no differences in other behaviors targeted by the intervention. CONCLUSIONS While a school-based intervention including counseling and access to an after-school exercise program is theoretically promising with public health potential, it was not effective in reducing BMI or key obesogenic behaviors. Our findings are important in highlighting that interventions targeted at the individual level are not likely to be sufficient in addressing the adolescent obesity epidemic without changes in social norms and the environment.
