BACKGROUND There are an increasing number of mobile applications that provide dietary guidance in supporting healthy lifestyle and disease management. However, the characteristics of these nutrition-related apps are not well analyzed. OBJECTIVE This study aimed to evaluate the functionality and quality of nutrition-related apps in China. METHODS Mobile apps providing dietary guidance were screened in Chinese iOS and android app stores using stepwise searching criteria in November 2017. Primary review was conducted by extracting information from the description of apps. Free apps that contain all the information of diet and nutrition, with the last update after 1st Jan 2016 were downloaded for further analysis on the nutritional functionality features based on the framework of Chinese Dietary Guidelines and on the market related features as well. The user version of the Mobile Application Rating Scale (uMARS) was used to assess the quality of apps. RESULTS Among the 44 downloaded nutrition-related apps screened from 628 apps with dietary guidance content, only 11(25%) were aimed exclusively for dietary guidance, the others were aimed for fitness guidance (17, 39%), disease management (11, 25%) and maternal health (5, 11%) respectively. The nutritional functionalities of the 44 apps included nutritional information enquiry (40, 91%), nutrition education (35, 80%), food record (34, 77%), diet analysis (34, 77%), and personalized recipes (21, 48%). Twelve out of 44 apps contained all of the above five nutrition related functionalities. The diet analysis and suggestions were mainly focused on energy (33/44, 75%), less on other factors like dietary structure (10/44, 23%). About 96% (42/44) of the apps provided social communication functionality and 59% (26/44) of the apps supported user incentives. Eight out of 44 apps (18%) also applied intelligent recognition technology. Using 5-point uMARS as scales of quality, the median scores of the 44 apps was 3.6 (IQR = 0.7). CONCLUSIONS Most nutrition-related apps are developed in the service of health management other than for dietary guidance exclusively. Although basic energy balance theory was generally applied, the nutritional functionality of the nutrition-related apps is relatively limited and not individualized. More efforts should be taken to integrate with the scientific nutritional knowledge and innovative technology in developing an app followed with complete and personalized dietary guidance.

Dietary Analysis

Background There are an increasing number of mobile apps that provide dietary guidance to support a healthy lifestyle and disease management. However, the characteristics of these nutrition-related apps are not well analyzed. Objective This study aimed to evaluate the functionality and quality of nutrition-related apps in China. Methods Mobile apps providing dietary guidance were screened in the Chinese iOS and Android app stores in November 2017, using stepwise searching criteria. The first screening consisted of extracting information from the app descriptions. Apps that (1) were free, (2) contain information on diet and nutrition, and (3) were last updated after January 1, 2016, were downloaded for further analysis. Nutritional functionalities were determined according to the Chinese Dietary Guidelines framework. Market-related functionalities were developed from previous studies and tailored to downloaded apps. The quality of apps was assessed with the user version of the Mobile App Rating Scale (uMARS). Results Out of 628 dietary guidance apps screened, 44 were nutrition-related. Of these, guidance was provided on diet exclusively (11/44, 25%), fitness (17/44, 39%), disease management (11/44, 25%), or maternal health (5/44, 11%). Nutritional functionalities included nutritional information inquiry (40/44, 91%), nutrition education (35/44, 80%), food record (34/44, 77%), diet analysis (34/44, 77%), and personalized recipes (21/44, 48%). Dietary analysis and suggestions mainly focused on energy intake (33/44, 75%) and less on other factors such as dietary structure (10/44, 23%). Social communication functionalities were available in 42 apps (96%), user incentives were supported in 26 apps (59%), and intelligent recognition technology was available in 8 apps (18%). The median score for the quality of the 44 apps, as determined on a 5-point uMARS scale, was 3.6 (interquartile range 0.7). Conclusions Most nutrition-related apps are developed for health management rather than for dietary guidance exclusively. Although basic principles of energy balance are used, their nutritional functionality was relatively limited and not individualized. More efforts should be made to develop nutrition-related apps with evidence-based nutritional knowledge, comprehensive and personalized dietary guidance, and innovative technology.

Abstract Aim: This study aimed to evaluate the functionality and quality of breast cancer-related apps which can be accessed from Turkey. Methods: The research covers 707 mobile applications, which were searched using the keywords "cancer", "oncology" and "breast cancer" in Google and App store stores between January and June 2019. The quality of apps was assessed with the user version of the Mobile App Rating Scale (MARS). Results: Mobile applications focus on communication, education and treatment order / plan categories. The average MARS quality score for applications in all of the two stores was determined as 3.42. According to the average score of the scale sub-dimensions; It was seen that they were ranked as functionality, aesthetics, information quality and participation. MARS scale sub-groups were listed as functionality, aesthetics, knowledge quality, and participation. Conclusion: e-Health is a subject that has just started to be used actively in health. Although basic information about breast cancer was used, information on prevention, early diagnosis and precautions was relatively limited and was not personalized. Support from healthcare professionals and further efforts should be made to develop evidence-based breast cancer knowledge and innovative technology and applications regarding cancer. Implications for practice: e-Health technologies are a good tool in breast cancer, but appear to lack evidence-based content and individual specific areas such as age and education level.

This study reviewed the content of mobile applications (apps) providing Alzheimer’s disease or related dementias (ADRD) information and assessed quality of the apps. Characteristics, content, and technical aspects of 36 apps in the U.S. Google Play Store and App Store were coded, and quality of the apps was evaluated using the Mobile Application Rating Scale. Caregiving (62.1%) and disease management (55.6%) content was frequently provided. Few apps had an app community (8.3%) or a reminder function (8.3%). Overall, quality of the apps was acceptable; apps by health care–related developers had higher quality scores than those by non-health care–related developers. This analysis showed that ADRD-related apps provide a range of content and have potential to benefit caregivers, individuals with ADRD, health care providers, and the general public. Collaboration of ADRD experts and technology experts is needed to provide evidence-based information using effective technical functions that make apps to meet users’ needs.

Validity And Reliability

Weak evidence exists on the relationship between nutritional knowledge and diet quality. Many researchers claim that this could be in part because of inadequate validation of the questionnaires used. The aim of this study was to develop a compact reliable questionnaire on nutrition knowledge for young and adult athletes (NUKYA). Researchers and the sport clubs medical staff developed the questionnaire by taking into consideration the latest athlete dietary guidelines. The questionnaire content was validated by a panel of 12 nutrition experts, and finally tested by 445 participants including athletes (n = 264), nutrition students (n = 49) and non-athletes with no formal nutrition knowledge (n = 132). After consulting the experts, 59 of the 64 initial items remained in the questionnaire. To collect the evaluation of experts, we used the content validity index, obtaining high indices for relevance and ambiguity (0.99) as well as for clarity and simplicity (0.98). The final questionnaire included 24 questions with 59 items. We ensured construct validity and reliability through psychometric validation based on the Classical Test Theory and the Item–Response Theory (Rasch model). We found significant statistical differences comparing the groups of nutrition knowledgeable participants with the rest of the groups (ANOVA p < 0.001). We verified the questionnaire for test–retest reliability (R = 0.895, p < 0.001) and internal consistency (Cronbach’s α=0.849). We successfully fit the questionnaire data to a rating scale model (global separation reliability of 0.861) and examined discrimination and difficulty indices for items. Finally, we validated the NUKYA questionnaire as an effective tool to appraise nutrition knowledge in athletes. This questionnaire can be used for guiding in educational interventions, studying the influence of nutrition knowledge on nutrient intake and assessing/monitoring sport nutritional knowledge in large groups.

OBJECTIVEThalamotomy of the ventral intermediate nucleus (VIM) is effective in alleviating medication-resistant tremor in patients with essential tremor (ET) and Parkinson's disease (PD). MR-guided focused ultrasound (MRgFUS) is an innovative technology that enables noninvasive thalamotomy via thermal ablation.METHODSPatients with severe medication-resistant tremor underwent unilateral VIM thalamotomy using MRgFUS. Effects on tremor were evaluated using the Clinical Rating Scale for Tremor (CRST) in patients with ET and by the motor part of the Unified Parkinson's Disease Rating Scale (UPDRS) in patients with PD and ET-PD (defined as patients with ET who developed PD many years later). Quality of life in ET was measured by the Quality of Life in Essential Tremor (QUEST) questionnaire and in PD by the PD Questionnaire (PDQ-39).RESULTSThirty patients underwent MRgFUS, including 18 with ET, 9 with PD, and 3 with ET-PD. The mean age of the study population was 68.9 ± 8.3 years (range 46–87 years) with a mean disease duration of 12.1 ± 8.9 years (range 2–30 years). MRgFUS created a lesion at the planned target in all patients, resulting in cessation of tremor in the treated hand immediately following treatment. At 1 month posttreatment, the mean CRST score of the patients with ET decreased from 40.7 ± 11.6 to 9.3 ± 7.1 (p < 0.001) and was 8.2 ± 5.0 six months after treatment (p < 0.001, compared with baseline). Average QUEST scores decreased from 44.8 ± 12.9 to 13.1 ± 13.2 (p < 0.001) and was 12.3 ± 7.2 six months after treatment (p < 0.001). In patients with PD, the mean score of the motor part of the UPDRS decreased from 24.9 ± 8.0 to 16.4 ± 11.1 (p = 0.042) at 1 month and was 13.4 ± 9.2 six months after treatment (p = 0.009, compared with baseline). The mean PDQ-39 score decreased from 38.6 ± 16.8 to 26.1 ± 7.2 (p = 0.036) and was 20.6 ± 8.8 six months after treatment (p = 0.008). During follow-up of 6–24 months (mean 11.5 ± 7.2 months, median 12.0 months), tremor reappeared in 6 of the patients (2 with ET, 2 with PD, and 2 with ET-PD), to a lesser degree than before the procedure in 5. Adverse events that transiently occurred during sonication included headache (n = 11), short-lasting vertigo (n = 14) and dizziness (n = 4), nausea (n = 3), burning scalp sensation (n = 3), vomiting (n = 2) and lip paresthesia (n = 2). Adverse events that lasted after the procedure included gait ataxia (n = 5), unsteady feeling (n = 4), taste disturbances (n = 4), asthenia (n = 4), and hand ataxia (n = 3). No adverse event lasted beyond 3 months. Patients underwent on average 21.0 ± 6.9 sonications (range 14–45 sonications) with an average maximal sonication time of 16.0 ± 3.0 seconds (range 13–24 seconds). The mean maximal energy reached was 12,500 ± 4274 J (range 5850–23,040 J) with a mean maximal temperature of 56.5° ± 2.2°C (range 55°–60°C).CONCLUSIONSMRgFUS VIM thalamotomy to relieve medication-resistant tremor was safe and effective in patients with ET, PD, and ET-PD. Current results emphasize the superior adverse events profile of MRgFUS over other surgical approaches for treating tremor with similar efficacy. Large randomized studies are needed to assess prolonged efficacy and safety.

South Africa (SA) is considered as the second largest economies in Africa with well-developed agricultural food production system. But food security is still a challenge at household level. Currently, in Africa, smallholder agriculture is recognized to contribute food security at household level. This study investigates the prevalence of food insecurity and nutritional knowledge of 78 local smallholder farmers in KwaZulu Natal (KZN) province of South Africa. The results from this study indicated that nutrition knowledge was poor and food insecurity was prevalent at >40% at the household level. It is therefore recommended that future agricultural training should include nutrition education based on FBDG (Food Based Dietary Guidelines) in their respective programs so as to attain a balanced diet for healthy and productive smallholder farmer communities

Adolescent nutrition and health issues need to be considered because adolescents are the next generation that determines the quality of human resources. Likewise, adolescents who are living in marginal conditions such as the Suku Anak Dalam (SAD) need to receive special attention due to the lack of access to information and nutrition education in these groups. Therefore, the purpose of this service is to educate adolescent nutrition and health in the indigenous community of Suku Anak Dalam (SAD). This activity was carried out in June - August 2020, in Pematang Kabau Village, Sarolangun Regency. The target is 10 SAD adolescents. This activity consists of providing education with power point media, leaflets, posters, and videos, as well as demonstrations using food models. The outputs of the community service activities are: (1) Media leaflets and health nutrition posters and; (2) Application of balanced nutrition in adolescents. The results showed that  a better change to aspects of nutritional knowledge where most targets can recognize and mention foods that are good for health, and can exemplify simple ways of monitoring nutritional status such as weighing, height, and measurement of Upper Arm Circumference. Based on this activity it is necessary to collaborate efforts from village officials, nutrition cadres and health workers to carry out routine nutrition and health monitoring on SAD adolescents so as to improve the health status of the SAD community.

Dietary mobile applications (apps) continue to hold promise for facilitating a healthy diet and managing nutrition. However, few studies have objectively evaluated the content and quality of such apps in Korea. The present study assessed the content and quality of dietary mobile apps using the Mobile App Rating Scale (MARS). We selected 29 dietary apps based on keywords and eligibility criteria for inclusion in the analyses. We conducted regression analyses to examine the association between app content and MARS scores. Most of the apps featured a tracking tool, while few featured rewards or follow-up management. Our quality assessment revealed that the top-rated apps have distinct levels of quality in terms of MARS scores. The regression analyses showed that the ways in which the apps provide information and motivate the users are statistically significant predictors of app quality. Our findings may facilitate the selection of dietary apps in Korea and provide guidelines for app developers regarding potential improvements in terms of content and quality.

Digital health interventions may improve different behaviours. However, the rapid proliferation of technological solutions often does not allow for a correct assessment of the quality of the tools. This study aims to review and assess the quality of the available mobile applications (apps) related to interventions for low back pain. Two reviewers search the official stores of Android (Play Store) and iOS (App Store) for localisation in Spain and the United Kingdom, in September 2019, searching for apps related to interventions for low back pain. Seventeen apps finally are included. The quality of the apps is measured using the Mobile App Rating Scale (MARS). The scores of each section and the final score of the apps are retrieved and the mean and standard deviation obtained. The average quality ranges between 2.83 and 4.57 (mean 3.82) on a scale from 1 (inadequate) to 5 (excellent). The best scores are found in functionality (4.7), followed by aesthetic content (mean 4.1). Information (2.93) and engagement (3.58) are the worst rated items. Apps generally have good overall quality, especially in terms of functionality and aesthetics. Engagement and information should be improved in most of the apps. Moreover, scientific evidence is necessary to support the use of applied health tools.

Abstract Background Obesity is a growing health problem which affects people from all age groups all over the world. Obese people do not feel motivated enough to change their lifestyle behaviors. Mobile applications can be used to motivate people.Objective To evaluate effect of nutrition education supported by MOtiVE mobile application on weight loss and quality of life (QoL).Methods In this randomized-controlled study, 79 overweight/obese adult patients who presented to University Hospital Outpatient Clinic between March-September 2018 to consult a dietitian were included. All the participants were provided a weight-loss diet program by the dietitian. Then, participants were randomized to experimental and control groups. During the first interview, all participants completed the questionnaire and anthropometric measurements were done. BMI, the scores obtained from different Quality of Life scales and Healthy Eating Index (HEI) were the dependent variables. The participants in the experimental group were provided with daily messages for 3 months via MOtiVE mobile application designed solely for this study. All the participants were asked to present three months later for a follow-up appointment. Using SPSS 25.0, change in BMI, QoL scores and other variables within both groups was assessed via Wilcoxon signed-rank test and McNemar chi-square test. p < 0.05 was considered statistically significant.Results Although 39 cases and 40 controls took the first test, 20 cases and 18 controls participants completed the study. The mean BMI decreased significantly in both groups being more predominant in cases as from 33.8 ± 6.0 kg/m2 to 32.8 ± 5.8 kg/m2(p = 0.001) in cases and from 33.3 ± 5.0 kg/m2 to 32.2 ± 4.7 kg/m2 (p = 0.006) in controls. Moreover, waist circumference decreased (p = 0.029), self-esteem (p = 0.035) and healthy eating scores (p = 0.007) increased only in cases significantly.Conclusions Nutrition education supported by MOtiVE mobile application improved anthropometric measurements, self-esteem, quality of life and healthy eating habits of the overweight/obese participants. Free mobile applications can be used in increasing motivation to adopt new behaviors in order to tackle obesity.Trial Registration: ClinicalTrials.gov NCT04026971
