RESUMEN
BACKGROUND: Research on digital technology to change health behavior has increased enormously in recent decades. Due to the interdisciplinary nature of this topic, knowledge and technologies from different research areas are required. Up to now, it is not clear how the knowledge from those fields is combined in actual applications. A comprehensive analysis that systematically maps and explores the use of knowledge within this emerging interdisciplinary field is required. OBJECTIVE: This study aims to provide an overview of the research area around the design and development of digital technologies for health behavior change and to explore trends and patterns. METHODS: A bibliometric analysis is used to provide an overview of the field, and a scoping review is presented to identify the trends and possible gaps. The study is based on the publications related to persuasive technologies and health behavior change in the last 18 years, as indexed by the Web of Science and Scopus (317 and 314 articles, respectively). In the first part, regional and time-based publishing trends; research fields and keyword co-occurrence networks; influential journals; and collaboration network between influential authors, countries, and institutions are examined. In the second part, the behavioral domains, technological means and theoretical foundations are investigated via a scoping review. RESULTS: The literature reviewed shows a clear and emerging trend after 2001 in technology-based behavior change, which grew exponentially after the introduction of the smartphone around 2009. Authors from the United States, Europe, and Australia have the highest number of publications in the field. The three most active research areas are computer science, public and occupational health, and psychology. The keyword "mhealth" was the dominant term and predominantly used together with the term "physical activity" and "ehealth". A total of three strong clusters of coauthors have been found. Nearly half of the total reported papers were published in three journals. The United States, the United Kingdom, and the Netherlands have the highest degree of author collaboration and a strong institutional network. Mobile phones were most often used as a technology platform, regardless of the targeted behavioral domain. Physical activity and healthy eating were the most frequently targeted behavioral domains. Most articles did not report about the behavior change techniques that were applied. Among the reported behavior change techniques, goal setting and self-management were the most frequently reported. CONCLUSIONS: Closer cooperation and interaction between behavioral sciences and technological areas is needed, so that theoretical knowledge and new technological advancements are better connected in actual applications. Eventually, this could result in a larger societal impact, an increase of the effectiveness of digital technologies for health behavioral change, and more insight in the relationship between behavioral change strategies and persuasive technologies' effectiveness.

BACKGROUND: Smoking rates among women are currently low, but they are the fastest growing segment of cigarette smoking population in developing countries. We aimed to assess the knowledge and perceptions towards smoking and to identify the factors related with level of knowledge and perceptions among adult women in urban slums. METHODS: This was a cross sectional study conducted on 250 adult (≥18 years of age) women attending primary care clinics in three slums of Karachi, Pakistan. A pre-tested and structured, interviewer administered questionnaire was used for data collection. Factors associated with level of understanding about smoking were analyzed with chi-square test. RESULTS: Most of the women knew that smoking has adverse effects on women and children's health but the knowledge of specific health effects was limited. About one third of the women knew that active smoking can cause lung disease, but only a small percentage (7%) knew that it could lead to heart disease. None of the women were aware that smoking contributes to infertility and osteoporosis. A small proportion of women were aware that smoking can lead to low birth weight (7%), congenital anomalies (5%) and less than 1% of women knew that it contributes to pregnancy loss, still birth and preterm delivery. The understanding of passive smoking affecting children's lung was low (20%) and a similar proportion voiced concern about the bad influence of maternal smoking on children. Educated women had better knowledge of health effects of smoking. Education was associated with having better knowledge about effects on women health in general (p = 0.02) and specific effects like lung (p = 0.03) and reproductive health effects (p < 0.001). Education was also associated with knowledge regarding effects on fetus (p < 0.001) and children (p < 0.005). Although most of the women disliked being around smokers, more than one third thought that smoking decreases boredom (39%), tension (38%) and also helps to relax (40%). A large proportion (48%) of women had the misconception that smoking helps to reduce weight. CONCLUSIONS: This study reveals that women are aware of the general ill effects of smoking but fail to identify smoking to be associated with female maladies particularly those who were illiterate and had lower levels of education. Understanding and attitudes needs to be improved by increasing health awareness and education of women in these urban communities with special emphasis on the effects of smoking on women's health.

BACKGROUND: Secondary prevention of cerebrovascular disease through dedicated stroke clinics has been shown to decrease recurrent vascular events in patients. However, there is limited literature describing such stroke clinic experiences from low and middle income countries. This study describes patient characteristics and observations made at the first systematized stroke clinic in Pakistan. METHODS: A retrospective audit of medical records of all patients presenting between September 2006 and August 2008 with a cerebrovascular event was conducted. Information about clinical presentation, modifiable risk factors and laboratory and radiological investigations was collected. Burden of disability was assessed using Modified Rankin score. Data was entered and analyzed using SPSS 14.0. RESULTS: 159 patients with a mean age of 57.0 +/- 13.9 years were included in this study and 34.6% of all patients were women. 108 patients were diagnosed with ischemic stroke (67.9%) while 34 patients presented with hemorrhagic stroke (21.4%) and 17 patients presented with transient ischemic attacks (10.7%). Hypertension was the most common modifiable risk factor seen in 78.0%, followed by diabetes in 40.3% and dyslipidemia in 31.5%. At presentation to clinic, only 26.0% patients with dyslipidemia and 64.5% patients with hypertension were on appropriate medications. CONCLUSION: A high prevalence of modifiable risk factors such as hypertension in stroke patients was observed and it presents an opportunity for conventional interventions in Pakistan. Systematized clinics for stroke and an algorithmic approach in primary care towards stroke may improve the implementation of evidence based secondary prevention strategies in developing countries.

The future of human societies depends on children being able to achieve their optimal physical and psychological development. Developmental delay is failure to acquire age-appropriate functionality. It may involve one or more streams of development. Responsive parenting has potential to promote better development. Primary health physicians are in the best arrangement to provide this assistance as they can monitor child's development longitudinally and understand the child's developmental trajectory better. Current strategy employed by majority of primary-care providers to monitor the trajectory is termed 'developmental surveillance'. It is "a flexible, continuous process whereby knowledgeable professionals perform skilled observations of children during the provision of health care". Age-appropriate developmental checklists are also used to record milestones as part of surveillance. Both, the American Academy of Pediatrics and the British Joint Working Party on Child Health Services, recommend developmental surveillance by physicians as a method of identification of developmental delays. Developmental screening, however, improves the accuracy of identifying children with delay, compared with surveillance. Primary health physicians should consider using developmental screening tools that are standardized, reliable, valid and practical in the office setting, be familiar with screening techniques which should be incorporated into ongoing care, and keep abreast of current literature. Pakistan, as a developing country, needs specific strategies to ensure that we seize all the chances to detect this delay at an earlier age and introduce intervention, in order to lessen the burden of the disability on child, family and society.

BACKGROUND: Intracranial stenosis is the most common cause of stroke among Asians. It has a poor prognosis with a high rate of recurrence. No effective medical or surgical treatment modality has been developed for the treatment of stroke due to intracranial stenosis. We aim to identify risk factors and biomarkers for intracranial stenosis and to develop techniques such as use of transcranial doppler to help diagnose intracranial stenosis in a cost-effective manner. METHODS/DESIGN: The Karachi Intracranial Stenosis Study (KISS) is a prospective, observational, case-control study to describe the clinical features and determine the risk factors of patients with stroke due to intracranial stenosis and compare them to those with stroke due to other etiologies as well as to unaffected individuals. We plan to recruit 200 patients with stroke due to intracranial stenosis and two control groups each of 150 matched individuals. The first set of controls will include patients with ischemic stroke that is due to other atherosclerotic mechanisms specifically lacunar and cardioembolic strokes. The second group will consist of stroke free individuals. Standardized interviews will be conducted to determine demographic, medical, social, and behavioral variables along with baseline medications. Mandatory procedures for inclusion in the study are clinical confirmation of stroke by a healthcare professional within 72 hours of onset, 12 lead electrocardiogram, and neuroimaging. In addition, lipid profile, serum glucose, creatinine and HbA1C will be measured in all participants. Ancillary tests will include carotid ultrasound, transcranial doppler and magnetic resonance or computed tomography angiogram to rule out concurrent carotid disease. Echocardiogram and other additional investigations will be performed at these centers at the discretion of the regional physicians. DISCUSSION: The results of this study will help inform locally relevant clinical guidelines and effective public health and individual interventions.

OBJECTIVE: To assess the level of awareness in the general public on risk factors, symptomatology and immediate treatment of stroke. METHOD: A cross sectional study was conducted in a sample of subjects visiting a tertiary care university hospital by means of a self-designed questionnaire. The study period extended between May and June, 2007. RESULTS: A total of 398 individuals were surveyed. Hypertension (69.1%) and stress (55.8%) were identified as two major risk factors for stroke. Among them 50.8% identified "Brain" as the principal organ involved in stroke out of which 78.2% of the response came from people whose level of education was intermediate-and-above. Around 13% of the study respondents did not know of any risk factor for stroke, while 11.6% of the study respondents didn't know about the alarming signs of stroke. The most frequent response (26.16%) to immediate management of stroke was to take the individual to Emergency Department/hospital. In all 56% reported that basic information about stroke was given to them by friend/relative. CONCLUSIONS: The overall awareness of the study population regarding stroke was shown to be inadequate by this study. Knowledge was significantly greater in participants of younger age and a higher level of education.

PURPOSE: The purpose of this study was to assess the prevalence of individuals at high risk for developing obstructive sleep apnea in the Pakistani population using a validated questionnaire. MATERIALS AND METHODS: This is a cross-sectional survey using a pre-validated, interviewer-administered questionnaire conducted at the Aga Khan University Hospital. All healthy individuals above 18 years of age attending a seminar were included as participants after consent. RESULTS: The percentage of people in the high-risk group was calculated to be 12.4% out of a population of 137. Presence of snoring, hypertension, and body mass index >27.5 kg/m(2) was found to be more prevalent in high-risk individuals. CONCLUSIONS: A significant proportion of the population is at high risk for obstructive sleep apnea syndrome.

BACKGROUND: Obstructive Sleep Apnea (OSA) is associated with many cardiovascular and psychiatric diseases. Day-time sleepiness is a common consequence of sleep apnea and correlates with road-traffic accidents (RTA). Pakistan has a high prevalence of factors which predispose an individual to OSA and death from RTAs are a huge burden. However there is a dearth of prevalence studies in this regard. We aim to understand local relevance of the disease and estimate the prevalence of individuals high-risk for OSA. METHODS: This cross-sectional survey was conducted among 450 individuals at Aga Khan University Hospital (AKUH), which is a tertiary care teaching hospital in Pakistan. We used the BQ as our measurement tool. Based on the responses, participants were grouped into high or low-risk for OSA. RESULTS: Our study sample size was 418 with 63.2% males. Mean age of our study population was 30.4 SD+/-12.3 years; and mean BMI was 23.2 SD+/-5 kg/m2. Out of the total sample size 24.9% reported snoring and there were twice as many males who snored as compared to females. Forty-five individuals reported that they had nodded off to sleep while driving at least once in their lifetime. On the other hand, the highest proportion of high risk individuals 47.6% was found in the age group 60 or above. The overall prevalence of individuals who were high risk for sleep apnea was 10%. CONCLUSION: A significant proportion of the population is at high-risk for OSA. Our study shows that despite low BMI and favorable craniofacial anatomy sleep apnea is still a locally relevant disease. Given the local relevance of OSAS, it is important to increase awareness among general population but more importantly among physicians of the developing countries, like Pakistan, about common clinical features and pertinent risk factors and complications of OSAS.

OBJECTIVE: To elucidate predictors of non-adherence among psychiatric patients presenting at a tertiary care hospital of Pakistan, for follow-up with consultant psychiatrist. METHODS: A convenient sampleof psychiatric patients from Aga Khan University Hospital was enrolled between April and May, 2005. An interviewer assisted, standardized questionnaire was used for data collection. Patients with cognitive deficit or psychosis and those presenting for the first time were not included in the study. RESULTS: Out of 128 patients, those with co-morbidity (32.81%) were less adherent than those without comorbidity (p-value:0.002). Adherence among depressed was 61.53%; psychotic was 58.82%; bipolar disorder was 73.91%. Reasons for non-adherence included sedation (30%), medication cost (22%), forgot to take medication (36%); and inability of the physicians to explain timing and dose (92%) or benefit of medication (76%). CONCLUSIONS: Non-adherence is a common and important issue. Treatment cost and co-morbidity should be reviewed in order to keep the medication regime affordable and comprehensible.

This retrospective, case-control study was carried out to find putative correlations of eNOS G894T polymorphism with essential hypertension (EHT) amongst adult Pakistani Pathans. We investigated a sample population of 332 (154 men, 178 women) comprising groups of 146 hypertensives (HTs) and 186 normotensives (NTs) by assays based on polymerase chain reaction followed by restriction endonuclease analysis. The distribution of the genotypes or alleles was not statistically different in hypertensive and normotensive groups. In conclusion, the present study in a population of Pakistani adult Pathans does not support the association of the eNOS gene G894T polymorphism to essential hypertension.
