The prevalence of frailty and related factors in community-dwelling Turkish elderly according to modified Fried Frailty Index and FRAIL scales.

AIM: The purpose of this study is to determine the prevalence of frailty with the Fried Frailty Index (FFI) and FRAIL scales (Fatigue, Resistance, Ambulation, Illness, Low weight) and also its associated factors in the community-dwelling Turkish elderly. METHODS: This is a cross-sectional population-based study in an urban area with a population of over 1,200,000. We sampled 1/100 of the elderly population. Frailty prevalence was assessed with a modified version of the FFI and FRAIL scale. Nutritional status was assessed by Mini Nutritional Assessment. Cognitive function was assessed by Mini-Mental State Examination. Depressive mood was assessed by GDS. Functional capacity was assessed by the instrumental activities of daily living scale. Falls and fear of falling were noted. Uni- and multivariate analyses were done to determine associated factors for frailty. RESULTS: A total of 906 community-dwelling elderly were included, in whom the mean age and standard deviation (SD) of age were 71.5 (5.6) years (50.6 % female). We detected frailty (female 30.4 %, male 25.2 %), pre-frailty and non-frailty prevalence with FFI as 27.8, 34.8, and 37.4 %, respectively. The prevalence of frailty (female 14.5 %, male 5.4 %), pre-frailty and non-frailty with the FRAIL scale was detected as 10, 45.6, and 44.4 %. Coexisting associated factors related with frailty in both models were found as depressive mood, cognitive impairment, and malnutrition in multivariate analysis. CONCLUSIONS: According to both scales, frailty was strongly associated with cognitive impairment, depressive mood, and malnutrition in the community-dwelling Turkish elderly population.

All-age relationship between arm span and height in different ethnic groups.

The objective of the present study was to establish multiethnic, all-age prediction equations for estimating stature from arm span in males and females. The arm span/height ratio (ASHR) from 13 947 subjects (40.9% females), aged 5-99 years, from nine centres (in China, Europe, Ghana, India and Iran) was used to predict ASHR as a function of age using the lambda, mu and sigma method. Z-scores for forced expiratory volume in 1 s (FEV1), forced vital capacity (FVC) and FEV1/FVC in 1503 patients were calculated using measured height and height calculated from arm span and age. ASHR varied nonlinearly with age, was higher in males than in females and differed significantly between the nine sites. The data clustered into four groups: Asia, Europe, Ghana and Iran. Average predicted FEV1, FVC and FEV1/FVC using measured or predicted height did not differ, with standard deviations of 4.6% for FEV1, 5.0% for FVC and 0.3% for FEV1/FVC. The percentages of disparate findings for a low FEV1, FVC and FEV1/FVC in patients, calculated using measured or predicted height, were 4.2%, 3.2% and 0.4%, respectively; for a restrictive pattern, there were 1.0% disparate findings. Group- and sex-specific equations for estimating height from arm span and age to derive predicted values for spirometry are clinically useful.

Bioequivalence study of low dose drospirenone/ethinyl estradiol 3 mg/0.03 mg film tablets under fasting conditions in Turkish healthy female subjects.

This bioequivalence research aims to evaluate the relative bioavailability and pharmacokinetic characteristics of ethinyl estradiol and drospirenone in the test preparation in comparison to the reference preparation during fasting conditions. A liquid chromatography method with tandem mass spectrometry was used to determine the concentrations of drospirenone and ethinyl estradiol in plasma. The pharmacokinetic parameters that were analyzed were the maximum plasma concentration (Cmax), time to achieve Cmax (tmax), elimination half life, and area under the concentration time curve of plasma (AUC0-t, AUC0-∞ for ethinyl estradiol, and AUC0-72h for drospirenone). Both the AUC and Cmax parameters were determined to be between 80.00% and 125.00% (90% confidence intervals), which is the acceptable range. Based on the study findings, it was concluded that the test formulation, which includes 3 mg of drospirenone and 0.03 mg of ethinyl estradiol, demonstrated bioequivalence when compared to the reference formulation.

Bioequivalence study of eltrombopag 75 mg film-coated tablets under fasting conditions during the Covid-19 pandemic in healthy Caucasian male subjects.

This study aims to determine the bioequivalence of the reference preparation and the test preparation containing eltrombopag when both were given during the COVID-19 pandemic while fasting. Participants in the research were healthy male Caucasian subjects. One film-coated tablet of the test preparation or one film tablet of the reference preparation, equivalent to 75 mg of eltrombopag, was given to the participants in a randomized order throughout each treatment session. At pre determined blood sampling points, blood samples were taken to determine the pharmacokinetics of eltrombopag. Eltrombopag concentrations in the samples were determined using an LC-MS/MS technique verified using ESI(-). The study results were used to calculate the rate (the maximum plasma concentration, or Cmax) and extent (area under the concentration-time curve of plasma, or AUC(0-72) and AUC(0-t) of eltrombopag absorption from the test preparation and reference preparation. The 90% confidence intervals (CI) of the ln-transformed AUC(0-72), AUC(0-t), and Cmax of eltrombopag met the bioequivalence requirements of 80.00-125.00%. Both trial preparations had a similar and very satisfactory safety profile.

Long-Term Immunogenicity and Safety of a Homologous Third Dose Booster Vaccination with TURKOVAC: Phase 2 Clinical Study Findings with 32-Week Post-Booster Follow-Up.

Vaccine-induced immunity wanes over time and warrants booster doses. We investigated the long-term (32 weeks) immunogenicity and safety of a third, homologous, open-label booster dose of TURKOVAC, administered 12 weeks after completion of the primary series in a randomized, controlled, double-blind, phase 2 study. Forty-two participants included in the analysis were evaluated for neutralizing antibodies (NAbs) (with microneutralization (MNT50) and focus reduction (FRNT50) tests), SARS-CoV-2 S1 RBD (Spike S1 Receptor Binding Domain), and whole SARS-CoV-2 (with ELISA) IgGs on the day of booster injection and at weeks 1, 2, 4, 8, 16, 24, and 32 thereafter. Antibody titers increased significantly from week 1 and remained higher than the pre-booster titers until at least week 4 (week 8 for whole SARS-CoV-2) (p < 0.05 for all). Seroconversion (titers ≥ 4-fold compared with pre-immune status) persisted 16 weeks (MNT50: 6-fold; FRNT50: 5.4-fold) for NAbs and 32 weeks for S1 RBD (7.9-fold) and whole SARS-CoV-2 (9.4-fold) IgGs. Nine participants (20.9%) tested positive for SARS-CoV-2 RT-PCR between weeks 8 and 32 of booster vaccination; none of them were hospitalized or died. These findings suggest that boosting with TURKOVAC can provide effective protection against COVID-19 for at least 8 weeks and reduce the severity of the disease.

Fatty liver is a good indicator of subclinical atherosclerosis risk in obese children and adolescents regardless of liver enzyme elevation.

AIM: To investigate the presence of association between nonalcoholic fatty liver disease (NAFLD) and subclinical atherosclerosis using carotid intima media thickness (c-IMT) in obese children and adolescents. Additionally, we wished to investigate the relationship between fatty liver and elevated liver enzymes. METHODS: A total of 157 obese patients (78 boys and 79 girls, mean age: 11.3 ± 2.6 years, age range: 6-16 years) were enrolled in the study. Aminotransferase, fasting glucose and lipid levels were determined. An oral glucose tolerance test was performed. The c-IMT was measured. Infectious and metabolic causes of elevated liver enzymes were excluded. The diagnosis of NAFLD was based on ultrasound scan. RESULTS: Obese patients with NAFLD had markedly increased carotid IMT (mean: 0.48 mm, 95% CI: 0.47-0.49) than those without NAFLD (mean: 0.45 mm 95% CI: 0.44-0.45, p < 0.001). The presence of NAFLD significantly increased c-IMT whether the patient had elevated liver enzyme or not (ANOVA, p < 0.001). In a multiple-regression model, only the presence of NAFLD was associated with increased c-IMT (ß = 0.031, SE (ß) = 0.008, p < 0.001). CONCLUSION: Obese children and adolescents with NAFLD are at risk of early atherosclerotic changes. As liver function tests are not sufficient to identify patients with fatty liver, ultrasonographic evaluation of NAFLD might be considered in all obese children and adolescents.

Safety and immunogenicity of an inactivated whole virion SARS-CoV-2 vaccine, TURKOVAC, in healthy adults: Interim results from randomised, double-blind, placebo-controlled phase 1 and 2 trials.

BACKGROUND: Development of safe and effective vaccine options is crucial to the success of fight against COVID-19 pandemic. Herein, we report interim safety and immunogenicity findings of the phase 1&2 trials of ERUCoV-VAC, an inactivated whole virion SARS-CoV-2 vaccine. METHODS: Double-blind, randomised, single centre, phase 1 and 2 trials included SARS-CoV-2 seronegative healthy adults aged 18-55 years (18-64 in phase 2). All participants, except the first 4 in phase 1 who received ERUCoV-VAC 3 µg or 6 µg unblinded and monitored for 7 days for safety purposes, were assigned to receive two intramuscular doses of ERUCoV-VAC 3 µg or 6 µg (an inactivated vaccine containing alhydrogel as adjuvant) or placebo 21 days apart (28 days in phase 2) according to computer-generated randomisation schemes. Both trials are registered at ClinicalTrials.gov (phase 1, NCT04691947 and phase 2, NCT04824391). RESULTS: Forty-four participants (3 µg [n:17], 6 µg [n:17], placebo [n:10]) in phase 1 and 250 (3 µg [n:100], 6 µg [n:100], placebo [n:50]) in phase 2 received ≥1 dose. In phase 1 trial, 25 adverse events AEs (80 % mild) occured in 15 participants (34.1 %) until day 43. There was no dose-response relationship noted in safety events in ERUCoV-VAC recipients (p = 0.4905). Pain at injection site was the most common AE (9/44;20.5 %). Both doses of ERUCoV-VAC 3 µg and 6 µg groups were comparable in inducing SARS-CoV-2 wild-type neutralising antibody (MNT50): GMTs (95 %CI) were 8.3 (6.4-10.3) vs. 8.6 (7.0-10.2) at day 43 (p = 0.7357) and 9.7 (6.0-13.4) vs. 10.8 (8.8-12.8) at day 60 (p = 0.8644), respectively. FRNT50 confirmed MNT50 results: SARS-CoV-2 wild-type neutralising antibody GMTs (95 %CI) were 8.4 (6.3-10.5) vs. 9.0 (7.2-10.8) at day 43 (p = 0.5393) and 11.0 (7.0-14.9) vs. 12.3 (10.3-14.5) at day 60 (p = 0.8578). Neutralising antibody seroconversion rates (95 %CI) were 86.7 % (59.5-98.3) vs 94.1 % (71.3-99.8) at day 43 (p = 0.8727) and 92.8 % (66.1-99.8) vs. 100 % (79.4-100.0) at day 60 (p = 0.8873), in ERUCoV-VAC 3 µg and 6 µg groups, respectively. In phase 2 trial, 268 AEs, (67.2 % moderate in severity) occured in 153 (61.2 %) participants. The most common local and systemic AEs were pain at injection site (23 events in 21 [8.4 %] subjects) and headache (56 events in 47 [18.8 %] subjects), respectively. Pain at injection site was the only AE with a significantly higher frequency in the ERUCoV-VAC groups than in the placebo arm in the phase 2 study (p = 0.0322). ERUCoV-VAC groups were comparable in frequency of AEs (p = 0.4587). ERUCoV-VAC 3 µg and 6 µg groups were comparable neutralising antibody (MNT50): GMTs (95 %CI) were 30.0 (37.9-22.0) vs. 34.9 (47.6-22.1) at day 43 (p = 0.0666) and 34.2 (23.8-44.5) and 39.6 (22.7-58.0) at day 60, (p = 0.2166), respectively. FRNT50 confirmed MNT50 results: SARS-CoV-2 wildtype neutralising antibody GMTs were 28.9 (20.0-37.7) and 30.1 (18.5-41.6) at day 43 (p = 0.3366) and 34.2 (23.8-44.5) and 39.6 (22.7-58.0) at day 60 (p = 0.8777). Neutralising antibody seroconversion rates (95 %CI) were 95.7 % (91.4-99.8) vs. 98.9 % (96.9-100.0) at day 43 (p = 0.8710) and 96.6 % (92.8-100.0) vs 98.9 % (96.7-100.0) at day 60 (p = 0.9129) in ERUCoV-VAC 3 µg and 6 µg groups, respectively. CONCLUSIONS: Two-dose regimens of ERUCoV-VAC 3 µg and 6 µg 28 days both had an acceptable safety and tolerability profile and elicited comparable neutralising antibody responses and seroconversion rates exceeding 95 % at day 43 and 60 after the first vaccination. Data availability Data will be made available on request.

The absence of insulin resistance in metabolic syndrome definition leads to underdiagnosing of metabolic risk in obese patients.

This study explores in a group of obese children and adolescents aged 10 to 16 years, the prevalence of metabolic syndrome (MS) according to the criteria of International Diabetes Federation (IDF). In addition, the prevalence of insulin resistance (IR) was investigated to find correlations between MS and IR. IDF definition was compared to a modified WHO definition. A total of 159 obese patients (74 male and 85 female; median age 12.7 years) were included in the study. Anthropometric measurements, blood pressure, and serum fasting lipids were evaluated. An oral glucose tolerance test (OGTT) was performed, and serum glucose and insulin levels were measured at 0, 30, 60, 90, and 120 min. Homeostasis model assessment of insulin resistance (HOMA-IR), quantitative insulin sensitivity check index (QUICKI), fasting glucose/insulin ratio (FGIR), Matsuda index, and total insulin levels during OGTT were calculated. For the IR diagnosis, we used cutoff values described in previous publications (HOMA-IR of >3.16, QUICKI of <0.357, FGIR of <7, and/or the sum of insulin levels during OGTT of >300 mIU/mL). MS prevalence, defined according to IDF criteria, was 34.6 %. Using the IDF definition, there was no statistically significant difference for the surrogate IR indices between patients with or without MS (QUICKI, 94.5 vs. 83.7 %), FGIR (81.1 vs. 78.8 %), HOMA-IR (70.9 vs. 63.5 %), and total insulin levels during OGTT (61.8 vs. 51.9 %). The Matsuda index values, the prevalence of fasting hyperinsulinemia, and impaired glucose tolerance were also similar in these two groups. In conclusion, IR was prominent in obese patients with and without MS. IDF definition of MS fails to discover individuals with IR, unless it is specifically investigated.

Interpopliteal distance percentiles to diagnose bowleg in 0-84 month-old Turkish children.

The purpose of this study was to determine the percentiles of interpopliteal distance to diagnose bowleg in 0-6 year-old children. Measurement of interpopliteal distance is a simple but valuable indicator in clinical examination to diagnose bowleg. We analyzed data from the anthropometry of Turkish children aged 0-6 years. The primary sampling unit included 21 family health centers (Aile Sagligi Merkezi) located in the city center and suburbs of Kayseri, Turkey. A total of 2,873 children and adolescents (1,419 boys, 1,454 girls), whose parents gave consent were included in the study. The smoothed percentiles and Z-scores were calculated by age and gender in 0-6 year-old children in quarter year intervals except for the 0-28-day newborn period. We found a significant correlation (r: 0.60, p < 0.001) between body weight and interpopliteal distance (after onset of walking). We consider that percentiles of interpopliteal distance can be used in the follow-up of children who may be at risk of bone and growth disorders. The zone between -2 standard deviation (SD) and +2SD values can be used to decide if the child has a normal growth pattern.

The association of serum sialic acid with carotid intima-media thickness and anthropometric and metabolic parameters in obese children and adolescents.

BACKGROUND: Sialic acid (SA) has been shown to be a strong predictor of cardiovascular mortality in adults. No study in children regarding the association of SA with cardiovascular risks exists in the literature. AIM: We aimed to investigate the association of SA with anthropometric and metabolic parameters and its correlation with metabolic syndrome (MS) and carotid intima-media thickness (IMT) in obese children. METHODS: A total of 154 obese children were included in the study (74 females, 80 males; mean age 11.3 ± 2.6 years). Anthropometric measurements including body fat percentage (BFP) were recorded. Fasting lipids and SA levels were measured. The carotid IMT was evaluated with ultrasonography. RESULTS: We found a significant correlation between serum total SA (TSA) levels and BFP (r = 0.25, p = 0.01 in the whole group; r = 0.43, p = 0.00 in girls). The group with BFP ≥95th percentile had higher TSA levels than the group with BFP <95th percentile (p = 0.04). TSA and carotid IMT were weakly correlated (r = 0.20, p = 0.01), but the significance was lost after correcting for BFP. No correlations were found between TSA and other anthropometric measurements. TSA did not correlate with serum fasting glucose, lipids, insulin or homeostasis model assessment-insulin resistance. TSA levels were not different between children with or without MS. CONCLUSION: Serum TSA levels are significantly correlated with BFP in obese children.

Body mass index percentiles for Turkish children aged 0-84 months.

BACKGROUND: Reference body mass index (BMI) percentiles are needed to follow secular changes in Turkish children aged 0-84 months. Obesity prevalence in this age group is also not well documented. AIM: The aim of this study was to determine BMI percentiles and the prevalences of overweight and obesity in Turkish children aged 0-84 months. The authors also tried to compare actual BMI status with World Health Organization (WHO) standards. SUBJECTS AND METHODS: This study used data from the Anthropometry of Turkish Children aged 0-6 years (ATCA-06) study. This cross-sectional study, conducted from September 2009 to May 2010 in Kayseri, Turkey, included 2683 children (1359 girls, 1324 boys) aged 0-84 months. Centile curves were constructed using the LMS method. RESULTS: It was found that BMI percentiles of Turkish children were higher than WHO standards in early childhood. The overweight and obesity prevalences were identical in both genders, 10.0% and 4.9%, respectively. CONCLUSION: This study provides both BMI reference values and prevalence figures for overweight and obesity in children aged 0-84 months, residing in Kayseri city, in Turkey. It is believed that these data can be of use in following secular changes as well as for comparisons with international standards.

Decreased high-density lipoprotein cholesterol and insulin resistance were the most common criteria in 12- to 19-year-old adolescents.

BACKGROUND: Metabolic syndrome (MetS) is characterized by a group of metabolic risk factors leading to an increase in diabetes mellitus and cardiovascular diseases. It is known that the pathologic processes such as hyperinsulinemia and atherogenic risk profile associated with the development of MetS begin during childhood and adolescence. AIM OF THE STUDY: To determine the prevalence of MetS and assess the association between MetS and certain demographic and lifestyle factors in a representative adolescent population. METHODS: The study was carried out in central and ten districts located around Kayseri Province, Central Anatolia. A total of 790 adolescents aged from 12 to 19 years were selected systematically from the schools. Criteria of MetS were modified from Adult Treatment Panel III: (1) waist circumference > 90th percentile (aged between 12 and 17 years) and >102 cm in male, >88 cm in female (for aged 18 and 19 years), (2) serum triglycerides [>or=136 mg/dl (aged between 12 and 16 years) and >or=150 mg/dl (for 17 and 19 years)], (3) high-density lipoprotein cholesterol [or= 95th percentile for gender, age and height, (5) insulin resistance HOMA index < 3.16. Multivariate regression model was performed to search for the association between MetS and demographic and lifestyle factors including gender, age, body mass index, settlement, socioeconomic class, smoking habit, physical activity and family history for diseases (cardiovascular diseases and diabetes mellitus). RESULTS: The overall prevalence of MetS was found as 10.8%. The prevalence was significantly higher in males than in females (13.5 and 8.6%, respectively). Low high-density lipoprotein cholesterol and insulin resistance were the most common criteria of the syndrome. According to the analysis, only gender and high socioeconomic class were weak-positive related factors with MetS. CONCLUSIONS: High prevalence of MetS especially among overweight and obese adolescents is a serious health problem. Early identification of the syndrome would contribute greatly to the prevention of diabetes and cardiovascular diseases in youth.

Body fat reference curves for healthy Turkish children and adolescents.

UNLABELLED: Childhood obesity is a major worldwide health problem. In addition to body mass index (BMI), body fat percentiles may be used to predict future cardiovascular and metabolic health risks. The aim of this study is to define new age- and gender-specific body fat centiles for Turkish children and adolescents. A total of 4,076 (2,276 girls, 1,800 boys) children and adolescents aged 6-18 years were recruited for this study. Total body fat was measured by a bioelectrical impedance noninvasive method. Body fat percentiles were produced by the LMS method. The body fat percentile curves of boys appear to rise from age 6 to 12 years and then slope downwards to age 15 years and then flatten off. The body fat % percentiles of girls increased until 14 years of age through 75th to 97th percentiles and then slope downwards, but through the third to 50th percentiles, they showed a downward slope after 14 years old. CONCLUSIONS: Since BMI may not always reflect body fat content, direct assessment of adiposity by a practical method would be significantly useful for clinical decisions. Therefore, this study provides normative data for body fat percentage in healthy Turkish children and adolescents. To this goal we used a practical and clinically applicable method. These references can be useful for evaluation of overweight and obesity.

Percentiles and mean values for neck circumference in Turkish children aged 6-18 years.

AIM: To provide neck circumference (NC) percentiles and mean values for Turkish children and to investigate their significance in clinical and epidemiological use. METHODS: Data were obtained from a cross-sectional screening study; DAMTCA II (Determination of Anthropometric Measurements in Turkish Children and Adolescents) in which 5481 subjects from 17 primary, secondary and high schools were included. NC percentiles were produced using the LMS method, and NC was compared with other parameters which define body fat distribution. RESULTS: The smoothed NC curves of 3rd, 5th, 15th, 25th, 50th, 75th, 85th, 90th, 95th and 97th percentiles were constructed by age and gender. The descriptive characteristics of collected data were presented as mean (SD: standard deviation) and median (Min-Max: minimum-maximum) to provide detailed information other than smoothed values. The most prominent finding of this study was that the NC of boys was greater, but not significantly higher, than that of girls until the age of 12 but later a prominent increase in the NC of boys is observed compared with girls. We compared obese and non-obese children in the 6-10, 11-13, 14-18 age groups, NC was found to be an important parameter to define obesity. CONCLUSIONS: This study provides NC percentiles, means and medians values and analyses their significance in obesity evaluation in clinical practice.

Growth hormone, insulin like growth factor-1, and insulin-like growth factor-binding protein-3 levels in the neonatal period: a preliminary study.

BACKGROUND: Growth hormone (GH), insulinlike growth factor-1 (IGF-1), and IGF-binding protein-3 (IGFBP-3) are used in the neonatal period for evaluation of diseases such as GH deficiency, intrauterine growth restriction, and hypoglycemia. However, GH level has been reported as a single value during the neonatal period. In this study, we attempted to determine the changes of GH, IGF-1, and IGFBP-3 in the neonatal period for each week. METHODS: One hundred and two appropriate-for-gestational age (AGA) term neonates who did not have any diseases that would interfere with GH-IGF axis were included in this cross-sectional study. Blood samples were collected and serum GH, IGF-1 and IGFBP-3 levels were measured by immunoradiometric analysis (IRMA) and weekly values were obtained for the first postnatal four weeks. RESULTS: We showed that GH level [median (1st-3rd quartile)] decreases from the first to the fourth postnatal week [25.1 (18.5-37.4); 17.2 (13.2-22.8); 17.6 (12.2-20.2); 14.4 (6.60-19.8) ng/mL, respectively)], IGF-1 and IGFBP-3 levels [median (lst-3rd quartile)] increase [41.7 (18.0-70.0); 55.9 (39.0-103); 53.0 (40.0-97.7); 71.7 (44.3-137) and 1852 (1597-2451); 2430 (1645-2838); 2841 (2280-3675); 3018 (2151-4189) ng/mL, respectively)]. CONCLUSIONS: GH, IGF-1 and IGFBP-3 values can be evaluated for each week separately instead of for the entire neonatal period.

Residents' views about family medicine specialty education in Turkey.

BACKGROUND: Residents are one of the key stakeholders of specialty training. The Turkish Board of Family Medicine wanted to pursue a realistic and structured approach in the design of the specialty training programme. This approach required the development of a needs-based core curriculum built on evidence obtained from residents about their needs for specialty training and their needs in the current infrastructure. The aim of this study was to obtain evidence on residents' opinions and views about Family Medicine specialty training. METHODS: This is a descriptive, cross-sectional study. The board prepared a questionnaire to investigate residents' views about some aspects of the education programme such as duration and content, to assess the residents' learning needs as well as their need for a training infrastructure. The questionnaire was distributed to the Family Medicine Departments (n = 27) and to the coordinators of Family Medicine residency programmes in state hospitals (n = 11) by e-mail and by personal contact. RESULTS: A total of 191 questionnaires were returned. The female/male ratio was 58.6%/41.4%. Nine state hospitals and 10 university departments participated in the study. The response rate was 29%. Forty-five percent of the participants proposed over three years for the residency duration with either extensions of the standard rotation periods in pediatrics and internal medicine or reductions in general surgery. Residents expressed the need for extra rotations (dermatology 61.8%; otolaryngology 58.6%; radiology 52.4%). Fifty-nine percent of the residents deemed a rotation in a private primary care centre necessary, 62.8% in a state primary care centre with a proposed median duration of three months. Forty-seven percent of the participants advocated subspecialties for Family Medicine, especially geriatrics. The residents were open to new educational methods such as debates, training with models, workshops and e-learning. Participation in courses and congresses was considered necessary. The presence of a department office and the clinical competency of the educators were more favored by state residents. CONCLUSIONS: This study gave the Board the chance to determine the needs of the residents that had not been taken into consideration sufficiently before. The length and the content of the programme will be revised according to the needs of the residents.

The risk analysis of arm fat area in Turkish children and adolescents.

AIM: The study examined the risk factors associated with arm fat area (AFA) in Turkish children and adolescents. METHODS AND SAMPLES: This study was conducted with 5358 (2621 boys, 2737 girls) children and adolescents aged 6-17 years. Height, weight, waist circumference, mid-upper arm circumference and triceps skinfold thickness were measured. Body mass index, fat percentage, waist-to-height ratio, and AFA were calculated. A questionnaire was used to obtain socio-demographic data. For age- and gender-specific AFA, three groups were created by percentiles (underweight<5th, healthy weight> or =5-84.99th, overweight> or =85th percentiles). Multinomial logistic regression analyses were performed to determine the risk factors. RESULTS: For the entire group, underweight and overweight prevalences were 4.7% and 14.9%, respectively. The body-size variables increased across age in Turkish boys and girls. The most significant risk factors for AFA were shown to be appetite, sleep duration, household income, and elevator use. CONCLUSION: AFA can be a significant index, in combination with other well-known anthropometric indices, in determining nutritional status.

Age references for the arm span and stature of Turkish children and adolescents.

BACKGROUND: Arm span reference values need to be determined in screening for certain clinical conditions. AIM: To determine arm span reference values for screening purposes in children and adolescents. SUBJECTS AND METHODS: Children and adolescents aged 6-17 were selected according to socio-economic levels. Age, pubertal period and sex-specific height and arm span are presented as means and standard deviation. Construction of the centile curves was performed using LMS software; the 3rd, 50th and 97th percentiles of each sex were compared. RESULTS: A total of 5358 primary and secondary school students (2737 girls, 2621 boys) were sampled for this study. Centile curves for both genders and linear regression equations to predict height from arm span were produced (height = 13.4396 + 0.9037(arm span); r =0.95 for boys and height = 16.4181 + 0.8865 (arm span); r =0.93 for girls). The correlation between arm span and height (r =0.83 p=0.001) was high and significant through ages 6-17. CONCLUSION: The findings provide a comparison of height and arm span for clinical purposes in critical percentiles (3rd, 50th and 97th), although these findings suffer from a lack of longitudinal examination to show the progress of these two anthropometric measurements.
