Effectiveness of eHealth weight management interventions in overweight and obese adults from low socioeconomic groups: a systematic review

Influence of eHealth Literacy and Health Promotion Behavior on Body Mass Index of Workers in the Public Sector

Background

Adequate eHealth literacy and health promotion behavior (HPB) are important to achieve good health-related quality of life. There is limited information on the influence of eHealth literacy and HPB on body mass index (BMI) in our setting and among public service workers.

Objectives

This study assessed the eHealth literacy, HPB, and BMI of public service workers and determined the influence of eHealth literacy and HPB on BMI.

Design

A descriptive cross-sectional design was adopted.

Methods

A simple random sampling technique was used to select 440 public service workers from civil service of redacted. A structured questionnaire was used to collect data on socio-demographics, eHealth literacy, and HPB. Weight and height were measured and BMI was calculated. Data were analyzed using frequency, percentage, mean, standard deviation, and logistic regression analysis. The significant level was set at 0.05.

Results

More than one quarter (28.2%) of respondents had low eHealth literacy, and more than one third (42.5%) had inadequate (30.0% fair and 12.5% poor) HPB. An average (50.5%) had a level of obesity that ranged from preobesity to type 2 obesity. There was a significant association between eHealth literacy and HPB with the BMI of respondents at p < .05.

Conclusion

There was inadequate eHealth literacy and HPB among public service workers. An average of the workers had a level of obesity that ranged from pre-obesity to type 2 obesity. There was a significant association between eHealth literacy and BMI and also between HPB and BMI of respondents. Community health professionals should assist public service workers to develop competencies and skills useful in evaluating health information on the Internet and applying such information to make informed decisions.

An exploration of customers' perceptions, preferences, experiences, and feasibility of offering standardized portions in restaurants

Excess caloric intake increases the risk of weight gain, and diet-related chronic diseases. Restaurants play an integral role in the portions of food people consume. Standardization of portion sizes in restaurants can help customers recognize appropriate portions. Through customer interviews, we aimed to assess and understand the feasibility, perceptions, and acceptability of standardized portions in restaurants. Kaiser Permanente partnered with three restaurants in Southern California to create alternative menu options of meals that would not exceed 700 calories. Kaiser Permanente members who lived within a 5-mile radius of the restaurants were informed through email about the study. Customers (N=33), who dined at one of the restaurants participated in a one-on-one semi-structured interview. Interviews were recorded, typed, transcribed verbatim, and analyzed using thematic analysis. Four themes emerged from the analysis: 1) Customers perceive standard portions as a better choice and the benefits outweigh regular portions; 2) Individual and restaurant-related factors may influence portion preferences; 3) Restaurant portions are perceived to be in excess of what customers need; and 4) Portion standardization is an evolving area for restaurants. Our findings suggest positive perceptions and acceptance of standardized portions among restaurant customers. Customer awareness and restaurant standardization procedures can improve customers' dining experience.

eHealth in obesity care

Obesity in adults is a growing health concern. Although effective, current treatment options have not been able to overcome the various factors that contribute toward rising obesity rates. eHealth might hold the capacity to improve the effectiveness, delivery and flexibility of some of these treatments. Here, we show that eHealth lifestyle change interventions delivered through smartphones (mHealth) can facilitate significant weight loss, making mHealth an attractive adjunct to clinical obesity care. However, evidence is currently limited to short-term effects, and is also lacking with regards to effectiveness based on socioeconomic status and ethnic group. This raises concerns around the potential and inadvertent widening of obesity prevalence disparities between groups as mHealth lifestyle change interventions are increasingly used in obesity care. Thus, we also describe opportunities to address these concerns and gaps in evidence.
