BACKGROUND: COVID-19 epidemiology changed with the emergence of SARS-CoV-2 variants of concern (VOC). Pakistan administered mostly inactivated vaccines. We investigated the association between VOC and breakthrough infections in a mixed-vaccination-status population of Karachi. METHODS: We investigated SARS-CoV-2 VOC tested in 392 respiratory specimens collected between May and December 2021. Data for age, sex, hospital admission, vaccinations, together with CT values of the diagnostic PCR test were analyzed. RESULTS: The median age of COVID-19 cases tested was 40 (27-57) years and 43.4% were female. Delta variants were most common (56.4%) followed by Alpha (15.9%), Omicron (12.2%), Beta/Gamma (11.3%), and others (4.3%). Eighteen percent of cases were hospitalized whereby, predominant VOC were Beta/Gamma (40.8%), Alpha (35.2%) and Delta (22.5%). Overall, 55.4% of individuals were fully vaccinated, 7.4% were partially vaccinated and 37.2% were unvaccinated. Most (74.6%) inpatients were unvaccinated. Vaccines comprised inactivated (85.34%), single-shot vector (8.62%), two-shot vector (3.02%) and mRNA (3.02%) types. Omicron variants showed lower viral loads as compared to Alpha, Beta/Gamma, and Delta (p = 0.017). The risk of infection with Delta and Omicron variants was higher, 8 weeks after vaccination. The majority of those with breakthrough infections after receiving inactivated vaccines acquired COVID-19 within 4 months of vaccination. CONCLUSION: Our data highlights the shifting of VOC from Delta to Omicron during 2021 and that COVID-19 vaccinations reduced both hospitalizations and viral transmission. It informs on the increased risk of breakthrough infection within 8 weeks of vaccination, indicating the need for booster vaccinations.

BACKGROUND: The primary healthcare system in Pakistan focuses on providing episodic, disease-based care. Health care for low-middle income communities is largely through a fee-for-service model that ignores preventive and health-promotive services. The growing burden of cardiovascular illnesses requires restructuring of the primary health care system allowing a community-to-clinic model of care to improve patient- and community-level health indicators. METHODS: We propose a model that integrates a Patient-Centered Medical Home (PCMH) with a Community-Based Health Information System (CBHIS) using hypertension (HTN) as an example. This protocol describes the integration and evaluation of the PCMH-CBHIS infrastructure through a population-based, observational, longitudinal study in a low-middle income, urban community in Pakistan. Participants are being enrolled in CBHIS and will be followed longitudinally over two years for HTN outcomes. A mixed-methods approach is adopted to evaluate the process of integrating PCMH with CBHIS. This involves building partnerships with the community through formal and informal meetings, focus group discussions, and a household health assessment survey (HAS). Community members identified with HTN are linked to PCMH for disease management. A customized electronic medical record system links community-level data with patient-level data to track changes in disease burden. The RE-AIM evaluation framework will be used to monitor community and individual-level metrics to guide implementation assessment, the potential for generalization, and the effectiveness of the PCMH in improving HTN-related health outcomes. Ethical clearance has been obtained from the Ethics Review Committee at Aga Khan University (2022-6723-20985). DISCUSSION: This study will evaluate the value of restructuring the primary care health system by ensuring systematic community engagement and measurement of health indicators at the patient- and community-level. While HTN is being used as a prototype to generate evidence for the effectiveness of this model, findings from this initiative will be leveraged towards strengthening the management of other acute and chronic conditions in primary care settings. If effective, the model can be used in Pakistan and other LMICs and resource-limited settings.

BACKGROUND: To provide access to primary care and universal health coverage, Pakistan requires 60,000 trained family physicians by 2030. At present, most primary care is provided by general practitioners (GPs) who do not have any post-graduate training. Empowering GPs through competency-based programs, that strengthen their knowledge and skills, may be a cost-effective strategy for improving healthcare quality. We describe the development and evaluation of FamMed Essentials, a modular, blended-learning program to improve clinical knowledge and skills of GPs. METHODS: This is a mixed method study. We used the CIPP (content, input, process and product) framework for course development and evaluation. We describe the steps used in content development, strategies for teaching and assessments, and evaluation of strengths and weaknesses of the program. In depth focus group discussions were conducted to gather insight on participants' and faculty's perceptions regarding the program's effectiveness. RESULTS: Of the 137 participants who have completed the program, 72% were women and 49% had been practicing for more than five years. We saw a significant improvement in knowledge across all modules (p = < 0.001) and perceived confidence in clinical skills (p = < 0.001). An objective assessment showed participants' competence in patient management. Participants reported a high level of satisfaction (4.4 ± 0.83 on a 5-point Likert Scale). Focus group discussions revealed a positive impact on clinical practice. Flexibility and use of different teaching and learning strategies were additional strengths. In addition, participants reported an interest in further training. Power outages were highlighted as a major challenge. CONCLUSION: In resource-constrained health systems, a modular, blended-learning, competency-based program is helpful to upgrade GPs knowledge without impacting their busy schedules. Accreditation of such programs and provision of a career trajectory for the trained GPs are pivotal to expansion of such initiatives.

Background: Metabolic syndrome (MetS) is a cluster of cardiometabolic risk factors which increase the likelihood of developing type 2 diabetes and cardiovascular disease. This study aimed to determine the prevalence of MetS among adolescents living in slums aged 11-18 years in Karachi, Pakistan. Methods: Data were collected from 689 adolescents attending five schools in two slum areas of Karachi, Korangi and Baldia, from February 2023 to March 2023. Measurements of weight, height, waist circumference, and blood pressure were obtained from the study participants. Blood samples were collected to assess fasting plasma glucose, High density lipoprotein HDL-cholesterol, and triglyceride levels as per National Cholesterol Education Program Adult Treatment Panel III (NCEP-ATP III). The prevalence of MetS was estimated using five diagnostic criteria, i.e., International Diabetes Federation (IDF-2007), World Health Organization, NCEP-ATP III, de Ferranti et al., and Cruz and Goran. Findings: The study revealed an overall prevalence of MetS among the adolescents in the two slum areas as 16.7%. A higher prevalence of MetS was observed among females (9.1%) and those with lower body mass index BMI (13.6%). The diagnostic criteria proposed by Cruz and Goran were found to be the most sensitive, with a MetS diagnosis rate of 22.93%. The study also identified several significant risk factors associated with MetS, including sedentary lifestyle (7.7%), lack of physical activity (7.5%), increased screen time (1.5%), lower fruit consumption (6.1%), and underweight (7.7%). Among slum-dwelling adolescents, low levels of HDL-cholesterol (33.96 ± 5.21), high triglyceride levels (161.45 ± 63.09), and elevated fasting plasma glucose levels (112.59 ± 28.92) were prevalent components of MetS. Interpretation: This study provides compelling evidence of a high prevalence of MetS among marginalised school-going adolescents in Karachi, Pakistan. The findings underscore the importance of early identification of adolescents at risk of developing MetS (especially those living in slum areas) and the implementation of effective preventive strategies to mitigate the risk of type 2 diabetes and cardiovascular disease in later life. Funding: None.

Background and Aims: COVID-19 vaccinations have reduced morbidity and mortality from the disease. Antibodies against severe acute respiratory syndrome coronavirus 2 (SARS­CoV­2) have been associated with immune protection. Seroprevalence studies revealed high immunoglobulin G (IgG) antibody levels to SARS-CoV-2 in the Pakistani population before vaccinations. We investigated the effect of BBIBP-CorV vaccination on circulating IgG antibodies and interferon (IFN)-γ from T cells measured in a cohort of healthy individuals, with respect to age, gender, and history of COVID-19. Methods: The study was conducted between April and October 2021. BBIBP-CorV vaccinated participants were followed up to 24 weeks. Antibodies to SARS-CoV-2 Spike protein and its receptor-binding domain (RBD) were measured. IFNγ secreted by whole blood stimulation of Spike protein and extended genome antigens was determined. Results: Study participants with a history of prior COVID-19 displayed a higher magnitude of IgG antibodies to Spike and RBD. IgG seropositivity was greater in those with prior COVID-19, aged 50 years or younger and in females. At 24 weeks after vaccination, 37.4% of participants showed IFN-γ responses to SARS-CoV-2 antigens. T cell IFN-γ release was higher in those with prior COVID-19 and those aged 50 years or less. Highest IFN-γ release was observed to extended genome antigens in individuals both with and without prior COVID-19. Conclusion: We found that IgG seropositivity to both Spike and RBD was affected by prior COVID-19, age and gender. Importantly, seropositive responses persisted up to 24 weeks after vaccination. Persistence of vaccine induced IgG antibodies may be linked to the high seroprevalence observed earlier in unvaccinated individuals. Increased T cell reactivity to Spike and extended genome antigens reflects cellular activation induced by BBIBP-CorV. COVID-19 vaccination may have longer lasting immune responses in populations with a higher seroprevalence. These data inform on vaccination booster policies for high-risk groups.

BACKGROUND: Inadequate sleep duration and poor sleep quality are associated with adverse cardiovascular outcomes. METHODS: Using data from the National Health Interview Survey, we compared self-reported sleep duration and quality among different groups: Whites, Chinese, Asian Indian, Filipino, and Other Asians. Outcome included Sleep duration (≥7 and <7 hours) and sleep quality (coded as a binary variable). RESULTS: We included 155,203 participants. The overall prevalence of ≥7 hours of sleep was 69.5% and poor sleep quality was reported by 73.9%. Compared to Whites and Chinese, Filipinos, and Other Asians were less likely to get adequate sleep (≥7 hours). All 4 Asian groups were less likely to report poor sleep quality compared with White individuals, while Asian Indians reported poor sleep quality less frequently compared with Chinese individuals. CONCLUSION: There are significant differences in sleep duration and quality between White and Asian groups, as well as within Asian subgroups. Further studies with disaggregated Asian subgroup data are needed to formally study these disparities.

OBJECTIVE: During the COVID-19 pandemic, several vaccines that were efficacious in randomised controlled trials were authorised for mass vaccination. In developing countries, inactivated vaccines were widely administered. While inactivated vaccines have been deemed effective in reducing disease severity, for healthcare personnel (HCP), effectiveness against SARS-CoV-2 infections is essential to reduce the risk to vulnerable patients and ensure a stable healthcare workforce. There are limited studies examining inactivated vaccines' effectiveness against SARS-CoV-2 variants of concern (VOCs) in real-world settings. We estimated the effectiveness of inactivated vaccines (BBIBP-CorV and CoronaVac) against reverse transcription PCR (RT-PCR)-confirmed SARS-CoV-2 infections among HCP in the setting of emerging SARS-CoV-2 VOCs in Pakistan. DESIGN: A retrospective matched, test-negative case-control analysis using existing data from an Employee Health database on HCP at a large, private healthcare system in Pakistan. PARTICIPANTS: 4599 HCP were tested between 1 April and 30 September 2021. Each case (PCR positive) was matched to two to six controls (PCR negative) by the date of the RT-PCR test (±7 days) to reduce bias. PRIMARY AND SECONDARY OUTCOME MEASURES: The primary outcome was vaccine effectiveness (VE) against SARS-CoV-2 infection. The secondary outcome was VE against symptomatic SARS-CoV-2 infection. Per cent VE was calculated using (1-OR)*100, with the OR of getting a PCR-confirmed SARS-COV-2 infection estimated using conditional logistic regression, after adjusting for age, gender, work area and history of SARS-CoV-2 infection. RESULTS: Inactivated vaccines were ineffective against SARS-CoV-2 infections after receiving the first dose (VE 17%, 95% CI -10, 39; p=0.261). They showed modest effectiveness ≥14 days after the second dose against SARS-CoV-2 infections (VE 30%, 95% CI 7, 48; p=0.015) and symptomatic SARS-CoV-2 infections (VE 33%, 95% CI 6, 52; p=0.002). CONCLUSIONS: Inactivated vaccines show modest effectiveness against SARS-CoV-2 infections in the setting of emerging VOCs. This builds a strong case for boosters and/or additional vaccination.

PURPOSE OF REVIEW: South Asia has around 1/6th of the current global population. Epidemiological studies suggest that South Asians living in South Asia and diaspora are at an increased risk of premature atherosclerotic cardiovascular diseases (ASCVDs). This is due to an interplay of genetic, acquired, and environmental risk factors. Due to its increasing share of the global population, clinicians need to know the reasons for this early predisposition, and strategies for early identification and mitigation. RECENT FINDINGS: South Asians have earlier onset of cardiometabolic risk factors such as insulin resistance, hypertension, and central adiposity. This increased risk is seen in both native South Asians and the diaspora. South Asians have earlier onset of ASCVD due to an earlier onset of cardiometabolic risk factors. Health promotion and early identification of these risk factors are essential to mitigate this ongoing crisis.

Anticipating staff shortage during the Omicron variant surge, we modified the US Centers for Disease Control and Prevention's contingency guidelines at a healthcare system in Pakistan. Infected staff had a SARS-CoV-2 rapid antigen test after 5-7 days of isolation, to decide a safe return-to-work. This led to signifcant cost savings without compromising patient/staff safety.

Introduction: Medical institutions worldwide faced an unprecedented situation during COVID-19 of identifying alternative strategies to sustain the continuum of learning process. This led to several innovations in the traditional medical curriculum. This study explored the effectiveness and feasibility of using the Peyton's framework modified for a virtual platform (Microsoft Teams) for teaching clinical skills to first and second-year medical students at The Aga Khan University, Karachi, Pakistan. Methods: In 2020-2021, the modified Peyton's framework was integrated in the clinical skills (CS) curriculum for all first- and second-year students (N=200). For evaluation, a mixed-method design was used, with pre-and post-session questionnaires. Students' satisfaction was obtained through the standard session evaluation tool of the university. For the qualitative arm, to explore the instructors' experiences, purposive sampling was used (n=8) and a focused group discussion (FGD) was conducted. Finally, performance of the students at the end of year summative Objective Structured Clinical Examination (OSCE) was compared with the students of previous year. Quantitative data were analysed using STATA® version 15.1, using paired t-test to compare the differences in OSCE scores in selected CS stations. A p-value of <0.05 was considered significant for all tests. The FGD was transcribed and analysed through manual content analysis. Results: Nine clinical skills (that included history and examination skills) were taught using the virtual platform. There was a significant improvement in post-session questionnaires in seven of these skills (p value <0.01). Session evaluations showed that most students were satisfied with the learning experience. The instructors showed that the online teaching offered a promising platform for teaching history taking skills. The OSCE scores showed mixed results, with significant improvement in two out of four repeated stations by using paired t-test [abdominal exam (87.33 ± 8.99, <0.001); and precordial examination (88.45 ± 8.36, 0.001)]. Conclusions: Modifying Peyton's framework to a virtual platform allowed us to sustain the continuum of clinical education during the COVID-19 pandemic. The results support the use of a blended learning environment for teaching clinical skills.

OBJECTIVE: To evaluate the real-world performance of the CDC's "Interim US guidance for risk assessment and work restriction for healthcare personnel with exposure to COVID-19" at a private healthcare system in Pakistan. STUDY DESIGN: Retrospective observational study. PLACE AND DURATION OF STUDY: The Aga khan University Hospital, Karachi, and its associated healthcare facilities in all four provinces of Pakistan, from February to September 2020. METHODOLOGY: Healthcare personnel (HCPs) assessed and tested for exposures to COVID-19 were included in the study. An exposure category was assigned to each HCP presenting with exposure to COVID-19 based on the CDC criteria. Percentage positivity was recorded and compared among the different exposure categories. Logistic regression analysis was used to identify variables significantly associated with COVID-19 infection. RESULTS: Three thousand Six hundred and forty-seven HCPs were assessed for exposure to COVID-19 of whom 603 (16.5%) tested positive. Percent positivity was highest in high-risk symptomatic HCPs (18.2%), 15.6% in low-risk symptomatic HCPs, and 11% in high-risk asymptomatic HCPs. After controlling for age, gender, area of work, and source of exposure, compared to low-risk asymptomatic HCPs, the odds of a positive SARS-CoV-2 PCR were 2.13 (95%CI: 1.49-3.04) for high-risk symptomatic, 1.66 (95% CI: 1.12-2.46) for low-risk symptomatic, and 1.18 (95% CI: 0.83-1.68) for high-risk asymptomatic HCPs. CONCLUSION: Regardless of exposure category, HCPs with symptoms consistent with COVID-19 have the highest likelihood of testing positive. The CDC exposure risk assessment criteria work best for symptomatic HCPs. Testing asymptomatic HCPs with high-risk exposures may not be necessary in low-resource settings with a limited healthcare workforce.

Objectives: During COVID-19 the re-opening of educational institutes was frequently debated, however with the decline in the number of COVID-19 cases, The Aga Khan University (AKU) in Karachi, Pakistan opened its campus for medical and nursing students after more than 6 months of closure. To ensure gradual resumption of activities on-campus, a combination of interventions was diligently deployed to minimize student infection rates. Scarce literature exists on students' perceptions regarding decisions implemented by university leadership. The aim of the study was to determine the efficacy of these interventions. Methods: We conducted a convergent, parallel, mixed-methods observational study targeting medical and nursing students. An online questionnaire was disseminated to elicit students' degree of (dis)agreement on a four-point Likert scale. Focused group discussions (FGDs) were conducted to comprehend reasons for (dis)agreement. Results: Total of 183 students responded to questionnaire (59.0% nursing, 67.8% female), 11 FGDs were conducted with 85 students. Interventions with highest agreement were mandatory face masks policy (94.54%), weekly mandated COVID-testing (92.35%) and students' Academic Bubble (91.26%); highest disagreement was for Sehat Check application (41.53%); and stay strong campaign (40.44%). Four themes emerged from FGDs: Effective safety interventions, Safety interventions with limited effectiveness, Utility of Sehat Check Application and Future recommendations for informing policy. Conclusion: It is paramount to seek student-feedback at forefront of university re-opening strategy. Clear communication channels are as important as an administrative response system's robustness. Bidirectional communication channels are fundamental and requisite during ever-changing policies and regulations. Engaging student representatives in decision making or implementation processes (such as "pilot" before "roll-out") would allow any potential issues to be managed early on. Gather real-time anonymous feedback and identify key areas that need further promulgation and those that need to be replaced with more effective ones.

OBJECTIVE: To assess the current knowledge level about diabetes and acceptance of nurse-led educational programmes among diabetic patients. Methods: The cross-sectional study was conducted at a community health centre in Karachi from August, 2018 to December, 2019 and comprised adult patients of either gender with diabetes. Data was collected using a predesigned questionnaire to record demographic information, participants' DM knowledge, self-management aspects and their opinions along with preferences for a DM educational support group. Data was analysed using STATA/SE 15.1. RESULTS: Of the 215 participants, 80(37%) were males and 135(63%) were females. The overall mean age was 55.8±14.5 yrs. Most participants had diabetes for ≥5 years 127(59%) and 141(66%) did not know their type of diabetes. Most participants were prescribed anti-diabetic medications 201(94%), and 45(2%) had forgotten to take their medication recently. Insulin was being used by 65(30%) participants, and, among them, 27(42%) reused syringes. Most patients struggled to make lifestyle modifications 133(62%), and 144 (67%) were willing to attend nurse-led diabetic education sessions. Conclusion: There was found to be a need of diabetes education support programme to address knowledge deficiencies, and a nurse-led programme was found to be acceptable to the majority of study subjects.

The intrauterine environment and early-life nutrition are regulated by maternal biomarkers in the blood and breast milk. We aimed to explore epigenetic modifications that may contribute to differential chemerin expression in maternal plasma, colostrum, and breast milk and find its association with fetal cord blood and infant weight at 6 weeks postpartum. Thirty-three gestational diabetes mellitus (GDM) mothers and 33 normoglycemic mothers (NGT) were recruited. Two maternal blood samples (28th week of gestation and 6 weeks postpartum), cord blood, colostrum, and mature milk were collected. Methylation-specific polymerase chain reaction and enzyme-linked immunosorbent assay were conducted. The weight of the babies was measured at birth and 6 weeks postpartum. Serum chemerin levels at the 28th gestational week and 6 weeks postpartum were significantly lower for the NGT group as compared to the GDM group; (P < 0.05). Higher colostrum chemerin concentrations were observed in the GDM group and remained elevated in mature milk as compared to NGT (P < 0.05). Colostrum and breast milk chemerin levels showed an independent association with infant weight at 6 weeks postpartum (r = 0.270; P = 0.034) (r = 0.464; P < 0.001). Forty percent GDM mothers expressed unmethylated chemerin reflecting increased chemerin concentration in the maternal blood. This pattern was also observed in newborn cord blood where 52% of samples showed unmethylated chemerin in contrast to none in babies born to normoglycemic mothers. The results of this study highlight the critical importance of altered chemerin regulation in gestational diabetic mothers and its effect during early life period and suggest a possible role in contributing to childhood obesity.

Hypertension is a major cause of cardiovascular disease and deaths worldwide especially in low- and middle-income countries. Despite the availability of safe, well-tolerated, and cost-effective blood pressure (BP)-lowering therapies, <14% of adults with hypertension have BP controlled to a systolic/diastolic BP <140/90 mm Hg. We report new hypertension treatment guidelines, developed in accordance with the World Health Organization Handbook for Guideline Development. Overviews of reviews of the evidence were conducted and summary tables were developed according to the Grading of Recommendations, Assessment, Development, and Evaluations approach. In these guidelines, the World Health Organization provides the most current and relevant evidence-based guidance for the pharmacological treatment of nonpregnant adults with hypertension. The recommendations pertain to adults with an accurate diagnosis of hypertension who have already received lifestyle modification counseling. The guidelines recommend BP threshold to initiate pharmacological therapy, BP treatment targets, intervals for follow-up visits, and best use of health care workers in the management of hypertension. The guidelines provide guidance for choice of monotherapy or dual therapy, treatment with single pill combination medications, and use of treatment algorithms for hypertension management. Strength of the recommendations was guided by the quality of the underlying evidence; the tradeoffs between desirable and undesirable effects; patient's values, resource considerations and cost-effectiveness; health equity; acceptability, and feasibility consideration of different treatment options. The goal of the guideline is to facilitate standard approaches to pharmacological treatment and management of hypertension which, if widely implemented, will increase the hypertension control rate world-wide.

Background: With the growing and complex nature of medicine, it is imperative for physicians to update their knowledge and skills to reflect current standards of care. In Pakistan, 71% of primary care needs are met by general practitioners (GPs). GPs are not required to complete structured training and no regulatory mandates exist for continuing medical education. We conducted a needs assessment to evaluate the readiness for competency-based updating of knowledge and skills, and the use of technology by practicing GPs in Pakistan. Methods: A cross-sectional survey inviting registered GPs across Pakistan was administered online and in-person. Questions pertained to physician demographics, practice characteristics, confidence in knowledge and skills, and preferred modes of updating knowledge and barriers. Descriptive analyses were performed for GPs and patient-related characteristics and bivariate analyses to evaluate the relationship between parameters of interest. Results: Of the 459 GPs who responded, 35% were practicing for <5 years and 34% reported practicing for >10 years. Only 7% had a post-graduate qualification in family medicine. GPs reported needing practice in neonatal examination (52%), neurological exam (53%), depression screening (53%), growth charts (53%) and peak flow meter use (53%), interpretation of electrocardiograms (ECGs, 58%) and insulin dosing for diabetes (50%). High workload (44%) was the most common barrier to updating clinical knowledge. Sixty-two percent used the Internet on a regular basis. Conclusion: Most GPs have no structured training and encounter gaps in knowledge and skills in clinical practice. Flexible, hybrid, and competency-based continuing medical education programs can be used to update knowledge and skills.

While the PCMH is the primary care model of choice for many healthcare systems, it is a relatively new area for college communities. The college health setting provides an important and challenging primary care platform because of developmental milestones that young adults face at this time of their lives. The Brown Primary Care Transformation Initiative (BPCTI) facilitated PCMH practice transformation efforts within a university center from 2013-2015. A mixed methods evaluative approach was used for baseline and follow-up periods as part of a broader transformation initiative that included interviews, surveys, focus groups, and observations. The college health practice was engaged in a number of other transformation activities concurrently. Results suggest that these multiple efforts, of which BPCTI's facilitation was one, together had a positive effect in this college health setting. This intervention provides a unique window into strengths and challenges for a college health practice as it seeks to transform its provision of primary care.

OBJECTIVES: To evaluate the association of metabolic syndrome with the varying degrees of obesity among children aged 6 to 11 years in Al Ain, United Arab Emirates (UAE). METHODS: As an ancillary to the primary study examining prevalence of MetS in a random sample of 1186 adolescents from 114 schools in Al Ain, parents and siblings aged 6 to 11 years were invited to participate in this study. After informed consent from parents and assent from children, trained nurses administered questionnaires to assess socio-demographic and lifestyle variables and conducted anthropometric measurements. Fasting blood samples were drawn to measure plasma lipids and glucose. We used Centers for Diseases Control and Prevention (CDC)-defined categories of body mass index (BMI = kg/m2 ) for normal weight (<85th percentile), overweight (≥85th to 94th percentile), and obese (≥95th percentiles). MetS was defined according to National Cholesterol Education Program's (NCEP)/Adult Treatment Panel III (ATP III) criteria. RESULTS: Of the total 234 siblings aged 6 to 11 years, 8.9% (95% Confidence Interval [CI]: 5.6-13.4) had MetS. The prevalence of MetS increased with the severity of obesity, 4.5% in normal, 16.7% in overweight, and 30.0% in obese subjects. The age, sex, and ethnicity adjusted odds (1.55, 95% CI: 1.23-1.96) of MetS increased significantly with per unit increase in BMI. CONCLUSIONS: The prevalence of MetS in study subjects increased with an increase in BMI. School-based interventions targeting metabolic risks in this population are urgently needed.

The aim of this case-control study was to assess TIMP2 level in subjects with or without metabolic syndrome (MetS) and to associate levels with non-alcoholic fatty liver changes (NAFLD). Thirty-three MetS subjects and 55 controls were recruited. Anthropometric data, lipid and glucose profile, TIMP2 and liver ultrasound was performed. High TIMP2 was seen in MetS group (145.28 ± 23.11 pg/ml) versus controls (19.06 ± 1.19 pg/ml; p < .001). Serum cholesterol, triglyceride, LDL-c and glucose levels were significantly higher in MetS subjects (p < .05). MetS individuals (72.72%) showed positive fatty liver changes versus 14.5% controls. Elevated TIMP2 positively correlated with waist circumference, body fat, blood glucose and NAFLD. Furthermore, every unit rise in waist circumference and TIMP2 and a unit decrease in HDL were associated with higher odds of developing NAFLD (p < .05). There may be concurrent relationship between TIMP2 and NAFLD in MetS that requires further evaluation to improve risk assessment and early diagnosis of MetS.
