The Effects of Dietary Mobile Apps on Nutritional Outcomes in Adults with Chronic Diseases : A Systematic Review and Meta-Analysis
Abstract Background Dietary interventions are effective prevention and treatment strategies for chronic diseases; however, they require extensive commitment, time, and resources. Dietary mobile applications (apps) have gained popularity and are thus being incorporated into dietary management. Objective The aim of this review is to assess the effects of the use of dietary mobile apps on nutritional outcomes in adults with chronic diseases. Methods A systematic review was conducted following PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines using MEDLINE, PubMed, Embase, and CINAHL databases. The protocol was registered on PROSPERO. Intervention studies evaluating the nutritional outcomes of dietary apps, published in English between January 1, 2007 and November 15, 2017 were included. The methodological quality of included articles was assessed via the Academy of Nutrition and Dietetics\u27 Quality Criteria Checklist: Primary Research. Heterogeneity was confirmed using the I2 index and a random-effects meta-analysis was performed for randomized controlled trials. Estimates of the pooled mean difference were calculated for app usage compared to no app usage. Main outcomes measure Nutritional outcomes, categorized as food-/nutrition-related, anthropometric measurements, pertinent clinical/biochemical data, and nutrition-focused physical findings, were extracted from the included intervention studies. Results Upon completion of the searches, 18,649 articles were identified, and data were extracted from 22 articles. Pooled estimates showed a significantly greater decrease in weight ( “2.45 kg, 95% CI “3.33 to “1.58 kg; P Conclusions The findings of this systematic review and meta-analysis indicate that dietary mobile apps are effective self-monitoring tools, and that their use results in positive effects on measured nutritional outcomes in chronic diseases, especially weight loss

Web-based interventions for weight loss and weight maintenance among rural midlife and older women: protocol for a randomized controlled trial
Background: Weight loss is challenging and maintenance of weight loss is problematic among midlife and older rural women. Finding effective interventions using innovative delivery methods that can reach underserved and vulnerable populations of overweight and obese rural women is a public health challenge.
Methods/Design: This Women Weigh-In for Wellness (The WWW study) randomized-controlled trial is designed to compare the effectiveness of theory-based behavior-change interventions using (1) website only, (2) website with peer-led support, or (3) website with professional email-counseling to facilitate initial weight loss (baseline to 6 months), guided continuing weight loss and maintenance (7-18 months) and self-directed weight maintenance (19-30 months) among rural women ages 45-69 with a BMI of 28-45. Recruitment efforts using local media will target 306 rural women who live within driving distance of a community college site where assessments will be conducted at baseline, 3, 6, 12, 18, 24 and 30 months by research nurses blinded to group assignments. Primary outcomes include changes in body weight, % weight loss, and eating and activity behavioral and biomarkers from baseline to each subsequent assessment. Secondary outcomes will be percentage of women achieving at least 5% and 10% weight loss without regain from baseline to 6, 18, and 30 months and achieving healthy eating and activity targets. Data analysis will use generalized estimating equations to analyze average change across groups and group differences in proportion of participants achieving target weight loss levels.
Discussion: The Women Weigh-In for Wellness study compares innovative web-based alternatives for providing lifestyle behavior-change interventions for promoting weight loss and weight maintenance among rural women. If effective, such interventions would offer potential for reducing overweight and obesity among a vulnerable, hard-to-reach, population of rural women
An evidence-based approach to the use of telehealth in long-term health conditions: development of an intervention and evaluation through pragmatic randomised controlled trials in patients with depression or raised cardiovascular risk
Background: Health services internationally are exploring the potential of telehealth to support the
management of the growing number of people with long-term conditions (LTCs).
Aim: To develop, implement and evaluate new care programmes for patients with LTCs, focusing on
two common LTCs as exemplars: depression or high cardiovascular disease (CVD) risk.
Methods
Development: We synthesised quantitative and qualitative evidence on the effectiveness of telehealth for
LTCs, conducted a qualitative study based on interviews with patients and staff and undertook a postal
survey to explore which patients are interested in different forms of telehealth. Based on these studies we developed a conceptual model [TElehealth in CHronic disease (TECH) model] as a framework for the
development and evaluation of the Healthlines Service for patients with LTCs.
Implementation: The Healthlines Service consisted of regular telephone calls to participants from health
information advisors, supporting them to make behaviour change and to use tailored online resources.
Advisors sought to optimise participants’ medication and to improve adherence.
Evaluation: The Healthlines Service was evaluated with linked pragmatic randomised controlled trials
comparing the Healthlines Service plus usual care with usual care alone, with nested process and economic
evaluations. Participants were adults with depression or raised CVD risk recruited from 43 general practices
in three areas of England. The primary outcome was response to treatment and the secondary outcomes
included anxiety (depression trial), individual risk factors (CVD risk trial), self-management skills, medication
adherence, perceptions of support, access to health care and satisfaction with treatment.
Trial results
Depression trial: In total, 609 participants were randomised and the retention rate was 86%. Response
to treatment [Patient Health Questionnaire 9-items (PHQ-9) reduction of ≥ 5 points and score of < 10 after
4 months] was higher in the intervention group (27%, 68/255) than in the control group (19%, 50/270)
[odds ratio 1.7, 95% confidence interval (CI) 1.1 to 2.5; p = 0.02]. Anxiety also improved. Intervention
participants reported better access to health support, greater satisfaction with treatment and small
improvements in self-management, but not improved medication adherence.
CVD risk trial: In total, 641 participants were randomised and the retention rate was 91%. Response to
treatment (maintenance of/reduction in QRISK®2 score after 12 months) was higher in the intervention
group (50%, 148/295) than in the control group (43%, 124/291), which does not exclude a null effect
(odds ratio 1.3, 95% CI 1.0 to 1.9; p = 0.08). The intervention was associated with small improvements in
blood pressure and weight, but not smoking or cholesterol. Intervention participants were more likely to
adhere to medication, reported better access to health support and greater satisfaction with treatment,
but few improvements in self-management.
The Healthlines Service was likely to be cost-effective for CVD risk, particularly if the benefits are sustained,
but not for depression. The intervention was implemented largely as planned, although initial delays and
later disruption to delivery because of the closure of NHS Direct may have adversely affected participant
engagement.
Conclusion: The Healthlines Service, designed using an evidence-based conceptual model, provided modest health benefits and participants valued the better access to care and extra support provided.
This service was cost-effective for CVD risk but not depression. These findings of small benefits at extra
cost are consistent with previous pragmatic research on the implementation of comprehensive telehealth

A Review of Psychosocial Factors that Facilitate HIV Infection Among Women Living in Canada & the United States: Implications for Public Health Policy
In Canada and the U.S., HIV infection among women has been associated with mental health symptoms, injection drug use, past trauma history, sexual partner characteristics, gender power inequalities, poverty, racial segregation and health care disparities. The psychosocial needs of women living with HIV often go unmet, facilitating HIV transmission, poor psychiatric outcomes and faster disease progression. Therefore, it is important to understand the complex biological, psychological, social and behavioral factors affecting women living with HIV. This article discusses urban women’s health from a biopsychosocial and behavioral perspective as well as the implications for health care policy and practice that are specific to HIV prevention and intervention
