Participatory Surveillance

BACKGROUND The increase in cell phone ownership in low- and middle-income countries (LMIC) has created an opportunity for low-cost, rapid data collection by calling participants on their cell phones. Cell phones can be mobilized for a myriad of data collection purposes, including surveillance. In LMIC, cell phone–based surveillance has been used to track Ebola, measles, acute flaccid paralysis, and diarrheal disease, as well as noncommunicable diseases. Phone-based surveillance in LMIC is a particularly pertinent, burgeoning approach in the context of the COVID-19 pandemic. Participatory surveillance via cell phone could allow governments to assess burden of disease and complements existing surveillance systems. OBJECTIVE We describe the protocol for the LeCellPHIA (Lesotho Cell Phone PHIA) project, a cell phone surveillance system that collects weekly population-based data on influenza-like illness (ILI) in Lesotho by calling a representative sample of a recent face-to-face survey. METHODS We established a phone-based surveillance system to collect ILI symptoms from approximately 1700 participants who had participated in a recent face-to-face survey in Lesotho, the Population-based HIV Impact Assessment (PHIA) Survey. Of the 15,267 PHIA participants who were over 18 years old, 11,975 (78.44%) consented to future research and provided a valid phone number. We followed the PHIA sample design and included 342 primary sampling units from 10 districts. We randomly selected 5 households from each primary sampling unit that had an eligible participant and sampled 1 person per household. We oversampled the elderly, as they are more likely to be affected by COVID-19. A 3-day Zoom training was conducted in June 2020 to train LeCellPHIA interviewers. RESULTS The surveillance system launched July 1, 2020, beginning with a 2-week enrollment period followed by weekly calls that will continue until September 30, 2022. Of the 11,975 phone numbers that were in the sample frame, 3020 were sampled, and 1778 were enrolled. CONCLUSIONS The surveillance system will track COVID-19 in a resource-limited setting. The novel approach of a weekly cell phone–based surveillance system can be used to track other health outcomes, and this protocol provides information about how to implement such a system.

Abstract Background Cardiovascular health (CVH) metrics among Chinese older adults are poorly understood. We investigated sex disparities in CVH metrics and their management among rural-dwelling older adults in China. Methods This community-based study included 5026 participants (age ≥ 65 years; 57.2% women) in the baseline survey of a multimodal intervention study in rural China. In March–September 2018, data were collected through face-to-face interviews, clinical examinations, and laboratory tests. We defined six CVH metrics (three behavioral factors—smoking, body mass index, and physical activity; three biological factors—blood pressure, total cholesterol, and blood glucose) following the modified American Heart Association’s recommendations. We performed descriptive analysis separately for men and women. Results Of all participants, only 0.8% achieved ideal levels in all six CVH metrics. Men were more likely than women to have ideal levels in all CVH metrics but smoking. Women had higher prevalence of ideal global (9.7% vs. 7.8%) and behavioral (18.3% vs. 9.5%) CVH metrics (p < 0.001), whereas men had higher prevalence of ideal biological CVH metrics (5.4% vs. 3.5%, p < 0.001). The prevalence of ideal global and behavioral CVH metrics increased with age in both women and men (p for trend< 0.001). Women were more likely to be aware of their hypertension and diabetes, and to receive antihypertensive treatment, while men were more likely to achieve the goal of high cholesterol treatment (p < 0.05). Conclusions The CVH metrics among older adults living in the rural communities in China are characterized by an extremely low proportion of optimal global CVH metrics and distinct sex differences, alongside poor management of major biological risk factors.

BackgroundNo study outside the UK has examined the diagnostic stability of psychotic disorders in a population-based sample.AimsTo determine diagnostic stability in a Dutch population-based psychosis incidence cohort, to examine the frequencies of diagnostic shifts to and from schizophrenic disorders and to report the revised relative risks of schizophrenic disorders for immigrants.MethodA 30-month follow-up study assessed the cohort (n=181) by means of face-to-face diagnostic interviews.ResultsDiagnostic stability of schizophrenic disorders was high (91%), but lower for other psychotic disorders. At follow-up, the initial diagnosis was adjusted to schizophrenic disorder more often than that the reverse occurred. Almost half (49%) of the patients who were not initially diagnosed as having a schizophrenic disorder received this diagnosis at follow-up. The relative risks for most immigrant groups were stable.ConclusionsSchizophrenic disorders are underdiagnosed, rather than overdiagnosed, at first presentation.

Background. Familial factors, which are partly genetic, influence risk for phobias. Prior family and twin studies, however, were based on a single lifetime assessment, which may be only moderately reliable.Methods. We obtained, 8 years apart, two assessments of lifetime history of five unreasonable fears and phobias (agoraphobia and social, situational, animal and blood-injury phobia) from face-to-face and telephone interviews from 1708 individual female twins from a population-based registry. We also obtained, 1 month apart, test–retest reliability on 192 twins. We fitted, using the program Mx, a measurement model that estimates the role of genetic and environmental risk factors correcting for measurement error.Results. Short-term reliability of the five phobias was modest (mean κ=0·46), but higher than long-term stability (mean κ=0·30). Unreliability occurred both for subject recall of unreasonable fears and for interviewer assessment of which fears constituted phobias. Examining fears and phobias together, in a multiple threshold model, results suggested that twin resemblance was due solely to genetic factors, with estimated total heritabilities, corrected for unreliability, of: any 43%, agoraphobia 67%, animal 47%, blood/injury 59%, situational 46% and social 51%. With the exception of animal phobia, similar results were obtained analysing phobias alone.Conclusions. Lifetime histories of unreasonable fears and phobias assessed at personal interview have substantial unreliability. Correcting for unreliability, the liability to fears and their associated phobias is moderately heritable. Individual-specific environmental experiences play an important role in the development of phobias, while familial–environmental factors appear to be of little aetiological significance.

Background. Patient education is effective for HTN treatment. There are many methods of patient education improving HTN control. Are there additive effects of combination of different educational methods for HTN treatment? Objective. To assess the effects of addition of the electronic educational material to doctor’s face-to-face education for HTN control. Method. We designed a randomized single blind study to compare the doctor’s face-to-face education alone and its combination with the electronic educational material over the cell phone. Participants were patients with a confirmed diagnosis of primary HTN. Electronic educational material over the cell phone was the intervention. Main measures were standard blood pressure measurements before and after 12 weeks of treatment. Result. The baseline characteristics of the intervention and control groups including the age, sex, SBP, DBP, and HTN control rate were not significantly different. After 12 weeks of follow-up, the blood pressure and the HTN control rate seemed worse in the combination group; however, the differences between the intervention group and the control group were not statistically significant. Conclusion. There were no additive effects in the combination of the doctor’s face-to-face education and the electronic educational material over the cell phone.

Objective: The aim of this study is to explore the diet intake pattern and nutritional status of rural population in Bangladesh.Methods: A population based crosssectional study was conducted in three rural villages of Mohespur Upazilla, Jhenaidah district, Bangladesh. Total 200 samples were collected purposively to conduct this study. Data were collected through personal face to face interview by structured and semi-structured questionnaire from the respondents.Results: The mean (± SD) age of the respondents was 35±16.6 years where 64% were male. The monthly dietary intake pattern of the respondents shows that majority of the respondents take pulses, fish, meat, egg, milk and fruits 1 to 2 time per month. Majority (94.5%) of the respondents take cereals 2 to 3 times per day. In case of nutritional status, majorities (47%) have normal nutritional status where 30% are overweight, 15% are obese and 8% are suffering from underweight. Study also shows that there is no relation between gender and nutritional status of the respondents.Conclusion: Finally, this study indicates that the overall dietary intake pattern of rural population in Bangladesh is poor. Further study should be needed in a large scale to explore the real scenario of dietary pattern and nutritional status of rural population in Bangladesh.DOI: http://dx.doi.org/10.3329/cmoshmcj.v13i2.21065

Type Headache

The prevalence of migraine and tension-type headache (TTH) varies considerably with respect to gender, age group and geographic regions. Methodological differences in the assessment and classification of cases are a major cause of this variability across studies, limiting the ability to perform true regional comparisons. We conducted three population-based studies in different German regions and assessed headache prevalence and headache characteristics in face-to-face interviews, applying standardized methods. We analysed the 6-month prevalence of migraine, TTH and their probable subtypes based on the new criteria of the International Headache Society (IHS). Among the 7417 participants in all three regions, the pooled 6-month prevalence of migraine, probable migraine, TTH and probable TTH was 6.75, 4.40, 19.86 and 11.61%, respectively. Despite the application of standardized classification methods, regional variations between 4.39 and 8.00% for migraine and 15.44 and 23.64% for TTH were observed, indicating differences in the local headache burden. Application of the new IHS criteria yielded headache categories that were not mutually exclusive, indicating a need for further discussion about the value of probable headache types in epidemiological studies.

IntroductionScreening is highly effective for cervical cancer prevention and control. Population-based screening programmes are widely implemented in high-income countries, although adherence is often low. In Portugal, just over half of the women adhere to cervical cancer screening, contributing for greater mortality rates than in other European countries. The most effective adherence raising strategies are based on patient reminders, small/mass media and face-to-face educational programmes, but sequential interventions targeting the general population have seldom been evaluated. The aim of this study is to assess the effectiveness of a stepwise approach, with increasing complexity and cost, to improve adherence to organised cervical cancer screening: step 1a—customised text message invitation; step 1b—customised automated phone call invitation; step 2—secretary phone call; step 3—family health professional phone call and face-to-face appointment.MethodsA population-based randomised controlled trial will be implemented in Portuguese urban and rural areas. Women eligible for cervical cancer screening will be randomised (1:1) to intervention and control. In the intervention group, women will be invited for screening through text messages, automated phone calls, manual phone calls and health professional appointments, to be applied sequentially to participants remaining non-adherent after each step. Control will be the standard of care (written letter). The primary outcome is the proportion of women adherent to screening after step 1 or sequences of steps from 1 to 3. The secondary outcomes are: proportion of women screened after each step (1a, 2 and 3); proportion of text messages/phone calls delivered; proportion of women previously screened in a private health institution who change to organised screening. The intervention and control groups will be compared based on intention-to-treat and per-protocol analyses.Ethics and disseminationThe study was approved by the Ethics Committee of the Northern Health Region Administration and National Data Protection Committee. Results will be disseminated through communications in scientific meetings and peer-reviewed journals.Trial numberNCT03122275

Abstract This study examined item nonresponse and its respondent and interviewer correlates by means of a population-based, panel survey of children aged 8 to 11 who were surveyed using standardised, face-to-face interviews. Using multilevel, logistic analyses with cross-level interactions, this article aims to examine which effects of item nonresponse are subject to children as respondents or to the interviewers and the interview setting. Depending on the type of question, we found different effects for respondent and interviewer variables, as well as interaction effects between child age/interviewer age as well as child gender/interviewer gender. However, interviewer variance is for the most part not significant.
