A Review of Efficacious Technology-Based Weight-Loss Interventions: Five Key Components

OBJECTIVE Obesity is highly prevalent among American adults and has negative health and psychosocial consequences. The purpose of this article was to qualitatively review studies that used technology-based interventions for weight loss and to identify specific components of these interventions that are effective in facilitating weight loss. MATERIALS AND METHODS We conducted a narrow, qualitative review, focusing on articles published in the last 10 years that used an experimental or pre/posttest design and used a technology-based intervention for weight loss. RESULTS Among the 21 studies reviewed, we identified the following five components that we consider to be crucial in technology-based weight-loss interventions that are successful in facilitating weight loss: self monitoring, counselor feedback and communication, social support, use of a structured program, and use of an individually tailored program. CONCLUSIONS Short-term results of technologically driven weight-loss interventions using these components have been promising, but long-term results have been mixed. Although more longitudinal studies are needed for interventions implementing these five components, the interface of technology and behavior change is an effective foundation of a successful, short-term weight-loss program and may prove to be the basis of long-term weight loss.

Catastrophizing, depression and pain-related disability.

OBJECTIVE The objective of the study was to examine catastrophizing, depression and their interactive effects in predicting disability in patients with chronic pain. METHOD A battery of questionnaires was mailed to primary care patients in a large integrated health care delivery system. The Patient Health Questionnaire was used to assess major depression, the Coping Strategies Questionnaire assessed catastrophizing and the Graded Chronic Pain Scale was used to assess pain intensity and two measures of disability, including self-report of pain interference and days missed from usual activities. Patient medical records were used to assess severe medical illness. Of the 5808 respondents, 2618 met criteria for chronic pain. Multiple regression analyses, covarying for age, gender, severe medical illness and pain intensity, estimated the main and interactive effects of catastrophic thinking and depression on two measures of pain-related disability. RESULTS Both catastrophic thinking and depression were statistically significant predictors of both measures of pain-related disability, with larger effect sizes observed for catastrophic thinking. CONCLUSIONS Routine assessment of both catastrophic thinking and depression is important in the treatment of chronic pain patients, and modification of these factors may reduce disability and increase the ability of chronic pain patients to participate in daily life activity.

Differences in Verbal Memory Performance in Postmenopausal Women Receiving Hormone Therapy: 17β-Estradiol Versus Conjugated Equine Estrogens

OBJECTIVE Much controversy exists and many questions remain unanswered about the effects of hormone therapy (HT) on cognition in postmenopausal women. There is growing evidence suggesting that HT compounds containing conjugated equine estrogen (CEE) have negative effects on cognition whereas 17β-estradiol (17β-E) either has positive or neutral effects. The present study sought to further examine this issue in a sample of postmenopausal women with risk factors for Alzheimers disease (AD). DESIGN Cross-sectional neuropsychological evaluation. SETTING Academic research clinic. PARTICIPANTS 68 healthy postmenopausal women (aged 49-68) receiving either 17β-E or CEE for at least one year with increased risk for AD. MEASUREMENTS Neuropsychological test battery of the cognitive domains of attention/working memory/processing speed, verbal memory, visual memory, and executive functioning. RESULTS Multivariate analyses of variance (MANOVA) showed significantly better verbal memory performance in women receiving 17β-E compared to women receiving CEE regardless of age, IQ, years of education, risk factors for AD (including APOE-ε4 carriership), duration of endogenous and exogenous estrogen exposure, concurrent progesterone use, or natural versus surgical menopause status. CONCLUSIONS Verbal memory performance was better in postmenopausal women receiving 17β-E compared to CEE in a sample population of women with risk factors for AD. Genetic risk for AD as well as other confounds did not affect this finding. The results suggest a differential effect of HT type on verbal memory, with 17β-E being a preferential compound. Further evaluation of HT types, regimens and duration of use on cognitive performance in postmenopausal women in a controlled longitudinal design is warranted.

Does improving mood in depressed patients alter factors that may affect cardiovascular disease risk

To determine if improvement in mood would ameliorate autonomic dysregulation, HPA dysfunction, typical risk factors and C-reactive protein in depressed patients with elevated cardiovascular disease risk (CVD), 48 depressed participants with elevated cardiovascular risk factors were randomized to a cognitive behavioral intervention (CBT) or a waiting list control (WLC) condition. Twenty non-depressed age and risk-matched controls were also recruited. Traditional risk factors (e.g., lipids, blood pressure) and C-reactive protein were assessed pre- and post-treatment six months later. Subjects also underwent a psychophysiological stress test while cardiovascular physiology was measured. Salivary cortisol was measured during the day and during the psychological stress test. At post-treatment, the CBT subjects were significantly less depressed than WLC subjects. There was no significant difference in change scores on any of the traditional risk factors or C-reactive protein, cortisol measures, or cardiovascular physiology, except for triglyceride levels and heart rate, which were significantly lower in treatment compared to control subjects. The normal controls exhibited no change in the variables measured during the same time. A significant improvement in mood may have little impact on most traditional or atypical risk factors, cortisol or cardiophysiology.

Binge drinking in women at risk for developing eating disorders.

OBJECTIVE To determine binge drinking rates in college-age women at risk for eating disorders and to examine factors related to binge drinking over time. METHOD Participants were 480 college-age women who were at high risk for developing an eating disorder (ED) and who had a body mass index (BMI) between 18 and 32. Participants were assessed annually for 4 years. RESULTS Participants reported high rates of binge drinking and frequent binge drinking throughout college. Binge drinking was positively correlated with dietary restraint, coping using substances, coping using denial, and life events. DISCUSSION The studys findings suggest that binge drinking is highly prevalent in women at high risk for developing eating disorders. Results also indicated that binge drinking was related to dieting and maladaptive coping patterns. Intervention for women with strong weight and shape concerns should also address problematic alcohol use.

HIV-related stigma: implications for symptoms of anxiety and depression among Malawian women

An estimated 11% of the adult population in Malawi, Africa, is living with HIV/AIDS. The disease has taken a toll on communities, resulting in high morbidity and mortality. Malawian women carry the burden of being caretakers for individuals infected with HIV while also worrying about their own health. However, little is known about how HIV/ AIDS affects psychological functioning among Malawian women in areas hit hardest by the epidemic. To that end, this paper examined the influence of HIV-related stigma on symptoms of anxiety and depression among 59 women 17–46 years old who were recruited from the Namitete area of Malawi. Women who reported greater worry about being infected with HIV and greater HIV-related stigma were significantly more likely to report greater symptoms of anxiety and depression. These findings suggest that interventions that reduce HIV-related stigma are likely to enhance psychological functioning among Malawian women, which in turn will improve the womens quality of life and well-being.

Sexual minority status and trauma symptom severity in men living with HIV/AIDS

Traumatic experiences are common among populations living with HIV; furthermore, the minority stress model indicates that sexual minority group members, such as men who have sex with men (MSM), are more likely to experience negative psychological outcomes after exposure to trauma, given the stress of minority stigma. The current study examined the prevalence of traumatic events and the impact of these events on trauma symptoms in a sample of 113 MSM and 51 men who have sex with women (MSW) who are living with HIV/AIDS. Rates of experiencing trauma were similar for both MSM and MSW. However, MSM, as sexual minority group members, were more likely to report symptoms of trauma and dissociation than MSW. The current study indicates that MSM may experience additional negative psychological outcomes after exposure to trauma. Findings are discussed in the context of implications for HIV prevention with sexual minority group members.
