RESUMEN
BACKGROUND: The Self-Directed Learning Readiness Scale (SDLRS) is a tool that helps in the assessment of the readiness of the students to pursue Self-Directed Learning (SDL). There are no documented studies on the validation of internal structure of the SDLRS among Indian medical students. Hence, the objective of this study is to validate the internal structure of SDLRS among Indian medical students using factor analysis and the Structural Equation Modelling (SEM) approach. METHODS: We administered Fisher's 40-item SDLRS to 750 students after receiving the ethics clearance and the author's permission and taking written informed consent from all the study participants (response rate: 92%). The exploratory factor analysis (EFA), confirmatory factor analysis (CFA), and Cronbach's alpha were performed using SPSS version 25 and the Lavaan package of R version 3.1.2. RESULTS: The values of the comparative fit index (CFI), standardised root-mean-square residual (SRMR), and root mean square error of approximation (RMSEA) were ≥ 0.9, ≤ 0.08, and ≤ 0.08, respectively, for a model fit to be acceptable. EFA showed that except for Q2 (loading score: 0.210), Q12 (loading score: 0.384), Q13 (loading score: 0.362), and Q25 (loading score: -0.219), all the items loaded well. After the exclusion of the aforementioned items, the factor loading scores for the items in the self-management, desire for learning, and self-control factors ranged from 0.405 to 0.753 (Cronbach α: 0.775), 0.396 to 0.616 (Cronbach α: 0.730), and 0.427 to 0.556 (Cronbach α: 0.799), respectively. The updated model was used for CFA, which displayed a good model fit. CONCLUSIONS: The resultant model consisting of 36 items is shown to have internal structure validity for Indian version of SDLRS, which can be used to assess medical students.

BACKGROUND AND AIM: A community-based rehabilitation programme, Sri Ramachandra University-Transforming Faces project, was initiated to provide comprehensive management of communication disorders in individuals with CLP in two districts in Tamil Nadu, India. This community-based programme aims to integrate hospital-based services with the community-based initiatives and to enable long-term care. The programme was initiated in Thiruvannamalai (2005) district and extended to Cuddalore (2011). The aim of this study was to identify needs related to speech among children with CLP, enroled in the above community-based programme in two districts in Tamil Nadu, India. DESIGN: This was a cross-sectional study. PARTICIPANTS AND SETTING: Ten camps were conducted specifically for speech assessments in two districts over a 12-month period. Two hundred and seventeen individuals (116 males and 101 females) >3 years of age reported to the camps. METHODS: Investigator (SLP) collected data using the speech protocol of the cleft and craniofacial centre. Descriptive analysis and profiling of speech samples were carried out and reported using universal protocol for reporting speech outcomes. Fleiss' Kappa test was used to estimate inter-rater reliability. RESULTS: In this study, inter-rater reliability between three evaluators revealed good agreement for the parameters: resonance, articulatory errors and voice disorder. About 83.8% (n = 151/180) of the participants demonstrated errors in articulation and 69% (n = 124/180) exhibited abnormal resonance. Velopharyngeal port functioning assessment was completed for 55/124 participants. CONCLUSION: This study allows us to capture a "snapshot" of children with CLP, living in a specific geographical location, and assist in planning intervention programmes.
RESUMEN
BACKGROUND: Application of e-learning and e-modules in medical education has been shown to have a positive impact on learning outcomes among all types of learners, across diverse educational settings. Despite its benefits, e-learning and e-modules has not yet reached its full potential in medical education in India. Objective of this study is to evaluate the perception of undergraduate students regarding e-learning and e-modules using an appreciative inquiry tool SOAR (Strengths, Opportunities, Aspirations, Results) analysis, and to identify the barriers and challenges for the same. METHODS: This longitudinal study was conducted among participants from three consecutive batches (n = 250 x 3) of first-year medical students and two consecutive batches (n = 100 x 2) of first-year dental students. The sample was selected using a purposive sampling method. Two structured and validated questionnaires were developed for this study based on the modified Zhou's Mixed Methods Model; the 'Knowledge, Attitude and Practice' Questionnaire (KAPQ) on e-learning and the feedback questionnaire (FBQ) on e-modules. The questionnaires were administered via MOODLE / hard copy, before and after the implementation of e-modules, respectively. Identified strengths, potential opportunities, probable aspirations and likely results for e-learning and e-modules were tabulated based on the qualitative analysis of perceptions of large number students sampled across three years. RESULTS: Six hundred and ninety students returned both questionnaires representing a response rate of 76.6%. Nine themes were identified in the "Strengths" domain as follows: Regular Update of Knowledge, Innovative Learning, Availability, Knowledge Sharing, Abundance of Information, Accessibility, Source of Knowledge, Creativity, and Increased Engagement. Eleven themes were identified in the "Opportunities" domain as follows: Clinical Skills training, Timesaving, Flexibility, Creativity, Increased engagement, Standardized content, Capacity building for students, Capacity building for faculty, Skills training, and Self-assessment. Thirteen themes were identified under the "Aspirations" domain with the three key themes being "maintaining and building on current strengths", "increasing potential opportunities", and "addressing the barriers and challenges identified in the responses to the KAPQ and FBQ questionnaire". Four themes identified for 'Barriers' were eye strain, distractions, preference for conventional methodologies, and internet connectivity. CONCLUSIONS: The findings of this qualitative study are based on the responses received from first-year medical and dental students of a Private University in Chennai, India. In this population of students, implementation of e-learning as blended learning using structured and interactive e-modules may provide more engagement during learning as well as support self-directed learning (SDL) directly or indirectly. Adoption of blended learning with e-modules as an integral part of curriculum planning may be beneficial for the achievement of Competency-Based Medical Education (CBME) goals in India.

BACKGROUND: Metacognition is the awareness and the capability to regulate one's own thinking process. Metacognition is critical in medical education for clinical reasoning and management. Hence, the objective of this study is to evaluate the construct validity and reliability of the Metacognitive Awareness Inventory (MAI) among first-year medical and dental students, from a private medical university in India, using confirmatory analysis and internal consistency method. MATERIALS AND METHODS: This was a cross-sectional study using convenient sampling. Fifty-two-item MAI was administered to 933 first-year medical and dental students from a private medical university in India. Exploratory factor analysis (EFA), principal component analysis, Cronbach's α, and confirmatory factor analysis with global fit indices were performed. Structural equation modeling (SEM) was performed to evaluate the relationship between the structural path and factors using AMOS version 22. RESULTS: During EFA, 12 items with <0.40 factor loadings were trimmed sequentially. The remaining items with respective factors had a good internal consistency of ≥ 0.9. Comparative fit index (0.78), goodness-of-fit index (0.8), adjusted goodness of fit index (0.77), Tucker-Lewis index (0.7), standardized root mean square residual (0.06), and root mean square error of approximation (0.09) values showed that six-factor model fits to satisfactory. Pearson's correlation coefficient was found to be high between factors (>0.80). SEM for each item (observed) and factor (unobserved) illustrated the hypothesized model. CONCLUSION: The resultant 40-item model based on MAI designed by Schraw is a valid and reliable tool for assessing the metacognitive awareness of Indian students. Employing a valid and reliable tool in assessing the metacognitive awareness will help the academicians in incorporating appropriate curricular interventions.
RESUMEN
BACKGROUND AND PURPOSE: Comprehensive management for communication disorders in individuals with CLP was provided in a community based program in two rural districts in Tamilnadu, India. This program provides services at the community to empower the families about CLP and treatment options. OBJECTIVE: To document the caregiver perceptions' of communication status and needs in children with repaired CLP. METHOD: Six Focus Group Discussions were conducted in Thiruvannamalai and Cuddalore districts in Tamil Nadu, India. Participants were 55 Caregivers of children (5-12 years of age) with repaired CLP. RESULTS: Most participants were concerned about their child's communication and few expressed concerns about specific errors in speech observed in their children. The caregivers recognized the need for and were willing to avail speech correction services. The focus group discussions highlighted some factors that need to be considered while planning a service delivery program for speech correction. The caregivers' expressed inability to independently carryout home training programs attributing it the lack of cooperation from their children. However they were open to receiving services if it was logistically convenient. CONCLUSION: This study provided the caregiver perceptions' of needs relating to communication in children with CLP. These need to be incorporated in the existing program to develop a model for speech intervention that would be feasible, sustainable and have good compliance.

Background Adolescence is a period of physiological, psychological and social transition between childhood and adulthood and is characterized by the onset of menstruation in girls. A adolescent girls are naïve about menstruation and they take time to adapt to these changes both socially and psychologically. This study was carried out to assess the psychosocial impact of menstrual problems among schoolgoing adolescent girls. Methods This study is a cross-sectional study carried out in 350 schoolgoing adolescent girls in the year 2012 in the Thiruvallur district of Tamil Nadu. Girls who attained menarche 1 year prior to the data collection were included in the study. Data regarding background characteristics and psychosocial impact of menstrual problems were collected. Data was analyzed using SPSS ver. 15 software. The χ2-test was carried out to assess the statistical significance at the 95% level of significance. Results The mean age of the participants was 14.7 years. In this study, 87.7% of the girls had at least one menstrual problem. Among these, 78.5% could not attend school during menstruation, 51.1% were unable to perform household/sports activities (p < 0.001). It was observed that dysmenorrhea and menorrhagia were at increased risk of absenting the girls from school (p < 0.05). Conclusion The key to a sound adolescent health programme is a holistic approach which also focuses on the psychological and social domain of health. This could be achieved by involving all the stakeholders like parents, teachers, etc. to work as a team. It is also essential to develop adolescent friendly health services at the grass root level.

Carpal Tunnel Syndrome (CTS) is an important problem among computer professionals. Hence the prevalence of CTS among computer professionals and risk factors were studied. 648 subjects were selected from 4,276 computer professionals from 21 companies by with simple random sampling method. CTS was diagnosed based on clinical features. The prevalence of CTS was found to be 13.1% (95% CI 10.5-15.7%). Subjects with over 8 years of computer work, over 12 hrs of work per day and system administrators were at a higher risk for CTS (OR 3.3, 4.9 and 2.5 respectively). Flexed or extended hand position had higher risk for CTS. Higher risk for CTS was found with higher exposure to computer work. Ergonomic considerations are important in facilitating proper positioning of hand while working with a computer. Further studies on CTS risk factors among computer professionals are essential for planning prevention.

STUDY OBJECTIVE: Adolescent girls face a gamut of problems of which the menstrual problems are the most common. Because menstrual problems are subtle, the problems often are unreported. The objective of this study was to estimate the prevalence of menstrual problems, namely dysmenorrhea, menorrhagia, and irregular menstrual cycles. DESIGN: Cross sectional study. SETTING: School-based study conducted in a rural school of the Thiruvallur district, Tamil Nadu. PARTICIPANTS: The participants were adolescent girls who attained menarche at least 1 year before the data collection period were selected using a simple random sampling method. A total of 350 participants were included in the study. INTERVENTIONS: No interventions were done. A structured, pretested questionnaire was used to collect data. MAIN OUTCOME MEASURES: The main outcome measured in this study was the prevalence of menstrual problems, namely dysmenorrhea, menorrhagia, and irregular menstrual cycles. RESULTS: The mean age of the study participants was 14.74 years. The mean age at menarche was 12.4 years. In this study, 87.7% of the girls suffered from a menstrual problem. Overall, dysmenorrhea was prevalent in 72.6%, and menorrhagia and irregular menstrual cycles were present among 45.7% and 31.7% of the participants, respectively. CONCLUSION: Menstrual problems form an important domain of adolescent health and because these problems go unreported, it is necessary that adequate attention and care is provided. The consequences of the neglect of menstrual problems results in impaired reproductive and sexual health in older women.

BACKGROUND: India currently is posed by the double threat of thinness and overweight/obesity among children. Different growth charts have taken different population and give different cut-off points to assess these conditions. OBJECTIVE: The objective of this study is to assess the anthropometry of school children, 5-18 years of age and thereby estimate the prevalence of childhood thinness, overweight and obesity. To analyze how the study population compares with that of Agarwal's growth chart. MATERIALS AND METHODS: The anthropometric measurements of all the students who were studying from 1(st) to 12(th) standards were taken from 27 randomly selected Government and private schools. Prevalence of thinness, overweight and obesity were assessed using two standards - Indian standard given by Agarwal and International Standards given by International Obesity Task Force (IOTF). RESULTS: The prevalence of thinness, overweight and obesity among 18,001 students enrolled as per Indian standard were 12.2%, 9.5% and 3% and as per International standard were 15.3%, 8.1% and 2.6% respectively. The mean and the 95(th) percentile values of body mass index for both boys and girls at all ages in this study are falling short of Agarwal's and IOTF values. Using international cut-offs as well as Indian cut-offs given by Agarwal, underestimate the prevalence of obesity among boys and girls of all age groups. CONCLUSION: This study shows that under and over-nutrition among school children is in almost equal proportions. There is an underestimation of obesity among children whenever an Indian or an International growth chart is used. Thus, this study brings out the need for a really representative growth chart.
RESUMEN
AIM: To estimate the prevalence and severity of attachment loss in an urban population of South India and to determine related risk indicators. MATERIALS AND METHODS: This population based cross sectional study used a subset of data from a large survey representative of urban population from Chennai city. The sample consisted of 900 subjects in the age range of 17 years to 87 years. Participants were interviewed using a structured proforma and subjected to a full mouth clinical examination of six sites per tooth. The prevalence of clinical attachment level (CAL) and association with various risk indicators was assessed. RESULTS: Out of the 900 subjects examined, 868 (96.4%) had CAL <5 mm and 32 (3.6%) had CAL ≥ 5 mm. Age, smoking, poor oral hygiene were found to be independent risk indicators for CAL (p<0.05). Smoking (pack years) was found to exhibit a dose response effect with CAL (Kendall's Tau coefficient = 0.098) (p<0.05). CONCLUSION: In this urban population, a low prevalence of CAL ≥ 5 mm was observed. Amongst the risk indicators evaluated, age, smoking and poor oral hygiene contribute significantly to attachment loss.
RESUMEN
OBJECTIVES: To measure the prevalence of behavioural risk factors for obesity among urban adolescent school children in Chennai, India. METHODS: This study was performed as a cross-sectional study using a World Health Organization-designed Global School-based Student Health Survey questionnaire (modified for India) among adolescent school children studying in 30 randomly selected secondary and higher secondary schools in Chennai city. 1842 adolescents studying in the VIII to XII standards were randomly selected for the study. RESULTS: In the present study, 40.7% of the students ate fruit one or more times per day and 74.5% of the students ate vegetables one or more times per day. Nearly 20% of the students ate fast food items on 4 to 7 days during the previous week. Among the students, 30.4% watched television for more than two hours per day. Nearly 68% of the girls and 22% of the boys did not participate in outdoor sports activities. When the pattern of physical activity of the students was assessed, it was observed that 15.6% were inactive, 43.4% were minimally active, and the remaining 41.0% belonged to the category of health enhancing physical activity. Among the students, 6.2% were overweight and 5.2% were obese. CONCLUSIONS: The prevalence of risk factors for obesity was quite high among the adolescents. This study also showed that a great proportion of overweight/obese adolescents had a correct perception of their body weight and they were making efforts to modify risk factors such as television viewing, computer use, a sedentary lifestyle, and unhealthy dietary habits.

BACKGROUND: Gestational diabetes mellitus (GDM) is a perfect window of opportunity for the prevention of DM in two generations, and its incidence is increasing in our country. Awareness of the condition among antenatal women will translate into prevention and early diagnosis of the disease. This study was done to determine the awareness of GDM among all the antenatal women who attend a Primary Health Center (PHC) for antenatal care. MATERIALS AND METHODS: A pretested questionnaire consisting of details on background characteristics, 12 questions focusing on Type 2 DM and GDM, and a question on the source of knowledge was administered to all women attending the antenatal clinic. Their responses were scored and the women were graded as having good, fair, or poor knowledge about GDM. RESULTS: One hundred and twenty antenatal women participated in the study. Mean age of the women was 23.8 years (SD: 2.94). Overall, 17.5% women had good knowledge, 56.7% had fair knowledge, and 25.8% women had poor knowledge about GDM. The major sources of awareness of GDM were reported to be television/radio, neighbors/friends, and family members. DISCUSSION: Only a small proportion of rural antenatal women had good knowledge about GDM. The awareness that untreated GDM may pose a risk to the unborn child was high among the study women. Health care workers have to play a greater role in bringing about awareness about GDM among antenatal women.
RESUMEN
BACKGROUND: Tuberculosis patients are registered in government clinics under Directly Observed Treatment Short-course (DOTS) program in Chennai city catering to 4.34 million population. With the entire country geographically covered under the DOTS program, research into socioeconomic impact of TB on patients and their households is crucial for providing comprehensive patient-friendly TB services and to document the benefits of DOTS. OBJECTIVE: To assess the social and economic impact of TB on patients registered under DOTS program and their families. MATERIALS AND METHODS: A cross-sectional study of 300 TB patients was done using a pre-coded semi-quantitative questionnaire between March and June 2007 in all the Tuberculosis Units (TUs) of Chennai city. RESULTS: Social and economic impact was perceived by 69.0% and 30.3% patients, respectively. About 24.3% suffered from both social and economic impact, while 75% patients suffered from any one form of impact. Social impact was perceived by more female patients as compared to males (80.7% vs. 62%; P < 0.001). More patients with extra-pulmonary disease (44.4%) and patients belonging to joint families (40.7%) perceived economic impact (P < 0.05). CONCLUSION: After 8 years of DOTS implementation, the present study has shown that with the availability of DOTS, percentage of patients who mortgaged assets or took loans has reduced. Social impact of TB is still perceived by two-thirds of the patients (69%). Elimination or reduction of social stressors with specific, focused, and intense social support services, awareness generation, and counseling to patients and families need to be built into the program.
RESUMEN
Background. Tuberculosis (TB) patients registered in the government clinics under the DOTS (Directly Observed Treatment, Short Course) program in Chennai city catering to about 4.3 million population. Objective. To estimate the pattern and overall costs incurred by the new patients (who have never had treatment for tuberculosis or have taken antituberculosis drugs for less than one month) registered under DOTS program in the treatment of tuberculosis in Chennai city. Methodology. A cross-sectional survey among new TB patients, who had completed intensive phase of antituberculosis treatment, was done using a precoded semi-structured questionnaire between March and June 2007. Information was collected on demographic, socioeconomic characteristics and expenditure for before and during treatment. Mean costs were used for comparison. Results. Among the 300 TB patients, most economically productive age group and 186 (62%) were males. The overall estimated total costs incurred right from the onset of symptoms until treatment completion was found to be Rs. 3211 (3.8% of annual family income) under DOTS program, which is less compared to previous studies. The overall mean total cost was significantly high among male (Rs. 3270; P < 0.01), employed (Rs. 3945; P < 0.01), and extrapulmonary patients (Rs. 3915; P < 0.01). Conclusion. The study has reiterated the fact that DOTS helps in reducing out-of-pocket expenses to patients with tuberculosis and hence is a cost-effective health intervention. This cost reduction may help to increase the access to the poor people which would help in achieving universal access to TB care services.
RESUMEN
Smoking has become an important global problem that poses serious health hazards. Today even teenagers have got trapped by this addictive habit. To curb this menace, the Government of Tamilnadu has proposed a ban on smoking in public places by introducing the Bill "Tamilnadu Prohibition of Smoking and Spitting 2002". A study was conducted in the month of February, 2003 to find out the response to this proposed ban among health providers. One hundred and twenty-seven hospital employees were studied using a one page questionnaire. The prevalence of smoking was found to be 12.6% (95% CI 6.9 to 18.3). The response of the study group to the proposed ban was recorded by asking them about their awareness, acceptability and their personal opinion about the ban. It was found that 94% of the smokers and 83% of the non-smokers were aware of the proposed ban and 50% of the smokers and 69% of non-smokers wanted the ban to be implemented. It was also found that 43.8% of the smokers and 52.3% of the non-smokers were confident that the ban on smoking in public places will be effective. They were also of the opinion that awareness had to be increased and the penalties had to be implemented strictly. Further studies on other population groups may have to be taken upto know about the impact of this important Act after it comes into effect.

OBJECTIVE: To estimate the population caesarean section rate in urban India. DESIGN: Population-based cross sectional study. SETTING: Madras City (Chennai), India. Seven hundred and eighty resident women who delivered in Madras between June 1997 and May 1999. METHODS: Cluster sampling was done using streets as cluster units. Thirty clusters were selected from 1255 clusters by the probability proportion to size method and 26 women were selected randomly from each cluster. MAIN OUTCOME MEASURES: Total and primary caesarean rates. RESULTS: Total population caesarean section rate was 32.6% (95% CI 27-38) and primary caesarean section rate was 25% (95% CI 20-30). Total caesarean section rates in the public, charitable and private sectors were 20%, 38% and 47%, respectively. Private sector deliveries had an odds ratio of 2.4 (95% CI 1.5, 3.8) of a primary caesarean section delivery in comparison with the public sector after adjustment for parity, age at delivery of mother and educational status. CONCLUSIONS: Forty-seven percent of births by caesarean section in the private sector is alarming and could implicate private sector care as the main contributing factor behind the high population caesarean section rates. Policymakers should urgently institute systems for accountability and ethical practice and regularly monitor all medical interventions, before large scale exploitation of the rural markets begins.
