Psychometric properties and structural validity of traditional Chinese version of the Richards-Campbell Sleep Questionnaire in intensive care unit patients without physical restraint.

BACKGROUND: Sleep assessment in the intensive care unit (ICU) is difficult and often unreliable. The most commonly used questionnaire for assessing ICU sleep, the Richards-Campbell Sleep Scale (RCSQ), has not been tested for reliability and construct validity in the Mandarin-Taiwanese speaking population. OBJECTIVE: The objective of this study was to test the construct validity and criterion validity of the traditional Chinese version of RCSQ (TC-RCSQ) in critically ill patients without physical restraint. METHODS: We adopted a cross-sectional study design. Adults aged 20 years and above were recruited from a plastic surgery ICU of a medical center. The Cronbach's alpha was used to test internal consistency; the validity testing included content validity, criterion validity, and construct validity. Criterion validity was analysed by testing the association of TC-RCSQ with the Chinese version of Verran and Snyder-Halpern Sleep Questionnaire and sleep parameter of actigraphy using the Pearson correlation coefficient; construct validity was analysed using exploratory factor analysis. RESULTS: A total of 100 patients were included with a mean age of 49.78 years. Internal consistency reliability suggested Cronbach's alpha of 0.93. Moderate to strong correlations of TC-RCSQ with Verran-Snyder-Halpern Sleep Questionnaire were identified (r = 0.36 to 0.80, P < 0.05). We found significant correlations of actigraphic sleep efficiency with difficulty of falling sleep, awakening times, sleep quality, and total score of the TC-RCSQ (r = 0.23, 0.23, 0.20, and 0.23, P < 0.05). One factor (named as overall sleep quality) was extracted by exploratory factor analysis with a total variance explained of 78.40 %, which had good construction validity. CONCLUSIONS: The TC-RCSQ yields satisfactory reliability and validity in critically ill patients. Actigraphic sleep efficiency may be a single index for objectively sleep assessment of sleep quality in patients without physical restraint. Both the TC-RCSQ and actigraphy can aid nurses to evaluate the sleep quality in critically ill patients without physical restraint.

Genetic Polymorphisms of lncRNA LINC00673 as Predictors of Hepatocellular Carcinoma Progression in an Elderly Population.

Long noncoding (lnc)RNAs are reported to be key regulators of tumor progression, including hepatocellular carcinoma (HCC). The lncRNA long intergenic noncoding RNA 00673 (LINC00673) was indicated to play an important role in HCC progression, but the impacts of genetic variants (single-nucleotide polymorphisms, SNPs) of LINC00673 on HCC remain unclear. A TaqMan allelic discrimination assay was performed to analyze the genotypes of three tagging SNPs, viz., rs9914618 G > A, rs6501551 A > G, and rs11655237 C > T, of LINC00673 in 783 HCC patients and 1197 healthy subjects. Associations of functional SNPs of LINC00673 with HCC susceptibility and clinicopathologic variables were analyzed by logistic regression models. After stratification by confounding factor, we observed that elderly patients (≥60 years) with the LINC00673 rs9914618 A allele had an increased risk of developing HCC under a codominant model (p = 0.025) and dominant model (p = 0.047). Moreover, elderly patients carrying the GA + AA genotype of rs9914618 exhibited a higher risk of having lymph node metastasis compared to those who were homozygous for the major allele (p = 0.013). Genotype screening of rs9914618 in HCC cell lines showed that cells carrying the AA genotype expressed higher LINC00673 levels compared to the cells carrying the GG genotype. Further analyses of clinical datasets from the Cancer Genome Atlas (TCGA) showed that LINC00673 expressions were upregulated in HCC tissues compared to normal tissues, and were correlated with advanced clinical stages and poorer prognoses. In conclusions, our results suggested that the LINC00673 rs9914618 polymorphism may be a promising HCC biomarker, especially in elderly populations.

Analysis of MUC6 Genetic Variants on the Clinicopathologic Characteristics of Patients with Hepatocellular Carcinoma.

Hepatocellular carcinoma (HCC) is the leading malignancy associated with cancer-related deaths worldwide. Many studies have indicated that mucin (MUC) expression plays an important role in cancer metastasis and recurrence. MUC6 expression is observed in gastric and oncocytic phenotypes and may play an important role during cancer progression. We found the level of MUC6 is lower in HCC patients but did not affect the survival of HCC patients. Therefore, in this study, we investigated the combined effect of MUC6 polymorphisms and exposure to environmental carcinogens on the susceptibility to and clinicopathological characteristics of HCC. Three single-nucleotide polymorphisms (SNPs) of MUC6 (rs61869016, rs6597947, and rs7481521) from 1197 healthy controls and 423 HCC patients were analyzed using real-time PCR. After adjusting for other co-variants, we found that carrying a CC genotype at MUC6 rs61869016 had a lower risk of developing HCC than wildtype carriers. Moreover, patients with a smoking habit who carried the C allele of rs61869016 and T allele of rs7481521 had a higher (B or C) Child-Pugh score than other genotypes, suggesting significant functional compromise and decompensated disease. Therefore, our findings suggest that genetic variations in MUC6 may corelate to HCC and indicate progression in HCC patients.

Impact of Aurora Kinase A Polymorphism and Epithelial Growth Factor Receptor Mutations on the Clinicopathological Characteristics of Lung Adenocarcinoma.

Lung adenocarcinoma (LADC) is the most common subtype of lung cancer worldwide and the epidermal growth factor receptor (EGFR) has a great influence on its clinical course, mainly due to the influence of different phenotypes. The Aurora kinase A (AURKA) would influence the progression of several solid malignancies. However, whether the interaction between EGFR phenotypes and AURKA would influence the clinical characteristics of LADC remains unknown. Herein, this study aimed to explore the effects of single-nucleotide polymorphisms (SNPs) of AURKA and EGFR phenotypes on the clinicopathological characteristics of LADC. Four loci of AURKA SNPs (rs1047972, rs2273535, rs6024836, and rs2064863) were genotyped using TaqMan allelic discrimination in 105 wild-type EGFR individuals and 167 LADC patients with EGFR mutations. After the statistical analysis, patients with LADC who had CT heterozygotes of AURKA rs1047972 had a lower risk of EGFR mutations than patients with wild-type homozygotes. Moreover, female and nonsmoking patients who carried the CT genotype of AURKA rs1047972 had a lower risk of EGFR mutation (p = 0.008 and p = 0.004, respectively). Moreover, in patients with EGFR mutations, AURKA SNP rs6024836 G allele (AG + GG) carriers had a lower risk of developing advanced-stage LADC (stage III or IV; odds ratio = 0.423, 95% confidence interval: 0.203-0.879, p = 0.019) than patients with AA homozygotes. Our results suggested that AURKA rs1047972 variants are significantly associated with EGFR mutations among patients with LADC, particularly in female and nonsmoking patients. AURKA variants may contribute to the pathological development of LADC.

Plasma Soluble Urokinase-Type Plasminogen Activator Receptor Level as a Predictor of the Severity of Community-Acquired Pneumonia.

The urokinase-type plasminogen activator receptor (uPAR) mediates various cellular activities and is involved in proteolysis, angiogenesis, and inflammation. The objective of this study was to investigate the association between soluble uPAR (suPAR) levels and community-acquired pneumonia (CAP) severity. A commercial enzyme-linked immunosorbent assay (ELISA) was performed to measure the plasma suPAR levels in 67 healthy controls and 75 patients with CAP. Our results revealed that plasma suPAR levels were significantly elevated in patients with CAP compared with the controls, and antibiotic treatment was effective in reducing suPAR levels. The plasma suPAR levels were correlated with the severity of CAP based on the pneumonia severity index (PSI) scores. Furthermore, lipopolysaccharide (LPS)-stimulation significantly increased uPAR expression in RAW 264.7 macrophages. In conclusion, plasma suPAR levels may play a role in the clinical assessment of CAP severity; these findings may provide information on new targets for treatment of CAP.

Impact of ADAM10 gene polymorphisms on hepatocellular carcinoma development and clinical characteristics.

A disintegrin and metalloprotease (ADAM) family proteins are type-I transmembrane glycoproteins with multiple functions in cell adhesion, migration, proteolysis and signaling. ADAM10 is a member of the ADAM family reportedly involved in cancer progression and has been shown to be overexpressed in hepatocellular carcinoma (HCC) tissues and significantly associated with tumor progression and shortened survival. This study investigated ADAM10's single nucleotide polymorphisms (SNPs) and their association to HCC development and regulation. Real-time polymerase chain reaction was used to analyze five SNPs of ADAM10 in 333 patients with HCC and 1196 controls without cancer. The results indicated that of the 333 patients with HCC, those who carried ADAM10 rs514049 (AC + CC) variants had a higher risk of developing lymph node metastasis (odds ratio [OR] = 5.087, p = 0.027), and those who carried ADAM10 rs653765 (GA + AA) variants had a higher risk of developing distant metastasis (OR = 3.346, p = 0.020) and higher levels of α-fetoprotein. In conclusion, our study demonstrated that the SNPs of ADAM10 are involved in HCC progression. ADAM10 SNPs may be used as therapeutic targets to evaluate poor prognoses for HCC.

Circulating level of high mobility group box­1 predicts the severity of community­acquired pneumonia: Regulation of inflammatory responses via the c­Jun N­terminal signaling pathway in macrophages.

High mobility group box­1 (HMGB­1) has been reported to serve significant roles in various inflammatory diseases. However, the correlation between the circulating level of HMGB­1 and severity of community­acquired pneumonia (CAP) remains unclear. The present study investigated differential alterations in plasma HMGB­1 levels of patients with CAP prior to and following antibiotic treatment, and further analyzed the association between CAP severity and HMGB­1 levels. Furthermore, lipopolysaccharide (LPS)­induced HMGB­1 expression in RAW264.7 macrophages and the relevant signaling pathways were examined. Plasma HMGB­1 levels of 90 patients with CAP and 52 healthy controls were measured using a commercial ELISA. The levels of plasma HMGB­1 were significantly elevated in CAP patients compared with the controls, and antibiotic treatment was effective in reducing HMGB­1 levels. Plasma HMGB­1 correlated with the pneumonia severity index score (r=0.566, P<0.001). Furthermore, LPS­stimulation significantly upregulated HMGB­1 secretion via the c­Jun N­terminal kinase (JNK) signaling pathway in RAW264.7 macrophages, whereas pretreatment with the JNK inhibitor SP600125 markedly downregulated LPS­induced HMGB­1 levels. In conclusion, plasma HMGB­1 levels may serve a role in the diagnosis and clinical assessment of CAP severity. These findings may provide information on novel targets for the treatment of CAP.

Association of single-nucleotide polymorphisms of high-mobility group box 1 with susceptibility and clinicopathological characteristics of uterine cervical neoplasia in Taiwanese women.

To date, no study associated the genetic polymorphisms of high-mobility group box 1 protein (HMGB1) with the development of uterine cervical cancer. We therefore conducted this study to investigate the associations of HMGB1 single-nucleotide polymorphisms (SNPs) with cervical carcinogenesis and clinicopathological characteristics of cancer patients. Five hundred two women, including 112 with invasive cancer, 85 with precancerous lesions of the uterine cervix, and 305 normal controls, were consecutively enrolled into this study. Analysis of HMGB1 SNPs was done by real-time polymerase chain reaction and genotyping. Our results found that the risk of susceptibility to cervical invasive cancer was 1.85 (95 % CI 1.12-3.04; p = 0.016) in women with TC and 1.99 (95 % CI 1.24-3.23; p = 0.005) in women with TC/CC after adjusting for age, using TT as a comparison reference in HMGB1 SNP rs1412125. In rs2249825, the increased risk was also seen for the development of cervical invasive cancer in women with CG [adjusted odds ratio (AOR) 2.04, 95 % CI 1.22-3.40; p = 0.006] or CG/GG (AOR 2.02, 95 % CI 1.22-3.32; p = 0.006) using CC as a comparison reference. An additional integrated in silico analysis confirmed that rs2249825 creates a binding site for v-Myb, which may affect HMGB1 expression. In conclusion, Taiwanese women with TC or TC/CC in HMGB1 SNP rs1412125 as well as CG or CG/GG in rs2249825 were susceptible to the development of cervical invasive cancer.

Association between Interleukin-18 Polymorphisms and Hepatocellular Carcinoma Occurrence and Clinical Progression.

We investigated the association between interleukin-18 (IL-18) polymorphisms and the susceptibility and clinicopathological state of hepatocellular carcinoma (HCC). In total, 901 participants, including 559 healthy controls and 342 patients with HCC, were recruited. The allelic discrimination of -607A/C (rs1946518) and -137G/C (rs187238) polymorphisms of IL-18 was assessed through real-time polymerase chain reaction by performing the TaqMan assay. The IL-18 -137G/C polymorphism but not the -607A/C polymorphism showed a significant association with the risk of HCC. Participants carrying the IL-18 -137 polymorphism with heterozygous G/C and homozygous CC genotypes showed a 1.987-fold increase (95% CI = 1.301-3.032; p = 0.001) in the risk of HCC compared with those homozygous for wild-type G/G. The 342 patients with HCC carrying the IL-18 -137G/C polymorphism were positive for hepatitis B virus (HBV) infection with an adjusted odds ratio of 1.668. Moreover, the 142 HBV positive patients with HCC and the IL-18 -137 polymorphism were positive for at least one C genotype and showed significant vascular invasion (p = 0.018). Furthermore, the level of α-fetoprotein was high in the patients carrying the IL-18 -137 polymorphism with GC+CC alleles (p = 0.011). In conclusion, the IL-18 -137G/C polymorphism with a GC+CC genotype could be a factor that increases the risk of HCC. Furthermore, the correlation between the IL-18 -137G/C polymorphism and HCC-related HBV infection is a risk factor for vascular invasion and has a synergistic effect that can further enhance HCC prognosis.

Validation of overnight oximetry to diagnose patients with moderate to severe obstructive sleep apnea.

BACKGROUND: Polysomnography (PSG) is treated as the gold standard for diagnosing obstructive sleep apnea (OSA). However, it is labor-intensive, time-consuming, and expensive. This study evaluates validity of overnight pulse oximetry as a diagnostic tool for moderate to severe OSA patients. METHODS: A total of 699 patients with possible OSA were recruited for overnight oximetry and PSG examination at the Sleep Center of a University Hospital from Jan. 2004 to Dec. 2005. By excluding 23 patients with poor oximetry recording, poor EEG signals, or respiratory artifacts resulting in a total recording time less than 3 hours; 12 patients with total sleeping time (TST) less than 1 hour, possibly because of insomnia; and 48 patients whose ages less than 20 or more than 85 years old, data of 616 patients were used for further study. By further considering 76 patients with TST < 4 h, a group of 540 patients with TST ≥ 4 h was used to study the effect of insufficient sleeping time. Alice 4 PSG recorder (Respironics Inc., USA) was used to monitor patients with suspected OSA and to record their PSG data. After statistical analysis and feature selection, models built based on support vector machine (SVM) were then used to diagnose moderate and moderate to severe OSA patients with a threshold of AHI = 30 and AHI = 15, respectively. RESULTS: The SVM models designed based on the oxyhemoglobin desaturation index (ODI) derived from oximetry measurements provided an accuracy of 90.42-90.55%, a sensitivity of 89.36-89.87%, a specificity of 91.08-93.05%, and an area under ROC curve (AUC) of 0.953-0.957 for the diagnosis of severe OSA patients; as well as achieved an accuracy of 87.33-87.77%, a sensitivity of 87.71-88.53%, a specificity of 86.38-86.56%, and an AUC of 0.921-0.924 for the diagnosis of moderate to severe OSA patients. The predictive outcome of ODI to diagnose severe OSA patients is better than to diagnose moderate to severe OSA patients. CONCLUSIONS: Overnight pulse oximetry provides satisfactory diagnostic performance in detecting severe OSA patients. Home-styled oximetry may be a tool for severe OSA diagnosis.

Elevated plasma stromal-cell-derived factor-1 protein levels correlate with severity in patients with community-acquired pneumonia.

BACKGROUND: The aim of this study was to investigate differential changes in plasma levels of stromal-cell-derived factor-1 (SDF-1) before and after antibiotic treatment in patients with community-acquired pneumonia (CAP) and observe the association between the severity of CAP and the plasma SDF-1 level. METHODS: We gathered blood specimens from 61 adult CAP patients before and after antibiotic treatment and from 60 healthy controls to measure the plasma concentrations of SDF-1 by using an enzyme-linked immunosorbent assay. RESULTS: The plasma SDF-1 concentration was elevated significantly in patients with CAP before receiving treatment compared with the controls and decreased significantly after the patients received treatment. Leukocyte (WBC) and neutrophil counts and C-reactive protein (CRP) levels decreased significantly after antibiotic treatment. Moreover, differences in the plasma concentration of SDF-1 were significantly correlated with PSI, CURB-65, and APACHE II scores (r = 0.389, P = 0.002, and n = 61; r = 0.449, P < 0.001, and n = 61; and r = 0.363, P = 0.004, and n = 61, resp.). CONCLUSIONS: An elevated plasma SDF-1 concentration can be used as a biological marker for the early diagnosis of CAP and for the early detection of its severity.

Dual thermo- and pH-responsive zwitterionic sulfobataine copolymers for oral delivery system.

A novel oral delivery system consisting of thermoresponsive zwitterionic poly(sulfobetaine methacrylate) (PSBMA) and pH-responsive poly(2-(diisopropylamino)ethyl methacrylate) (PDPA) is synthesized via free radical polymerization. This copolymer can self-aggregate into nanoparticles via electrostatic attraction between ammonium cation and sulfo-anion of PSBMA and successfully encapsulate anticancer drug, curcumin (CUR), with highest loading content of 2.6% in the P(SBMA-co-DPA) nanoparticles. The stimuli-responsive phase transition behaviors of P(SBMA-co-DPA) copolymers at different pH buffer solution show pH-dependent upper critical solution temperature (UCST) attributed to the influence of protonation/deprotonation of the pH-responsive DPA segments. Through the delicate adjustment of the PSBMA/PDPA molar ratios, the stimuli-responsive phase transition could be suitable for physiological environment. The kinetic drug release profiles demonstrate that P(SBMA-co-DPA) nanoparticles have the potential as oral delivery carriers due to their effective release of entrapped drugs in the stimulated intestinal fluid and preventing the deterioration of drug in stimulated gastric fluid.

Usefulness of plasma YKL-40 in management of community-acquired pneumonia severity in patients.

Plasma YKL-40 level has been reported as playing a significant role in community-acquired pneumonia (CAP). However, the correlation between plasma level of YKL-40 and the severity of CAP has not been reported. This study identifies the relationship between plasma level changes of the YKL-40 gene in adult patients hospitalized with CAP. The ELISA was used to measure the plasma YKL-40 level from 61 adult CAP patients before and after antibiotic treatment and from 60 healthy controls. The plasma YKL-40 levels were significantly increased in patients with CAP compared to normal controls. Moreover, the plasma concentration of YKL-40 correlated with the severity of CAP based on the pneumonia severity index (PSI) score (r = 0.630, p < 0.001), the CURB-65 (confusion, uremia, respiratory rate, BP, age 65 years) score (r = 0.640, p < 0.001), the Acute Physiology And Chronic Health Evaluation II (APACHE II) score (r = 0.539, p < 0.001) and length of hospital stay (r = 0.321, p = 0.011), respectively. In conclusion, plasma YKL-40 may play a role in the diagnosis and clinical assessment of CAP severity, which could potentially guide the development of treatment strategies.

The impact of IGF-I gene polymorphisms on coronary artery disease susceptibility.

BACKGROUND: Coronary artery disease (CAD) was the second leading cause of death for the past 3 years in Taiwan. The insulin-like growth factor (IGF) system is considered a new risk factor of CAD because investigations show that the levels and bioactivity of IGF-I and IGFBP-3 (where IGFBP is insulin-like growth factor-binding protein) may be involved in elevating the risk of CAD. This study investigated the relationships among IGF-I +1770, IGF-I +6093, and IGFBP-3 -202 genetic polymorphisms and CAD in the Taiwanese population. METHODS: A total of 581 subjects, including 390 non-CAD controls and 191 patients with CAD, were recruited and the isolated DNA was subjected to real-time polymerase chain to evaluate the effects of these three polymorphic variants on CAD. RESULTS: Our results showed a significant association between the IGF-I +1770 gene polymorphism and increased risk of CAD. Furthermore, CAD patients with a minimum of one mutant C allele, T/C or C/C, in IGF-I +1770 gene polymorphism had significantly high blood pressure including systolic blood pressure (SBP; P = 0.025) and diastolic blood pressure (DBP; P = 0.004), compared to CAD patients with T/T homozygotes. Moreover, CAD patients with a minimum of one mutant A allele, G/A or A/A, in the IGF-I +6093 gene polymorphism had a 1.695-fold elevated risk of congestive heart failure (CHF), compared to CAD patients with the G/G homozygote. CONCLUSIONS: Polymorphism of IGF-I +1770 was associated with increased CAD risk. In CAD patients, the contributions of IGF-I +1770 and +6093 could be through the effect on blood pressure in CAD patients.

Nurses' knowledge and barriers regarding pain management in intensive care units.

AIM: To explore nurses' knowledge and barriers regarding pain management in intensive care units. BACKGROUND: Pain is a common and treatable condition among intensive care patients. Quality care of these patients depends on the pain knowledge and pain management skills of critical care nurses. However, no single study has explored these nurses' knowledge of and perceived barriers to pain management in Taiwan. DESIGN: A cross-sectional study. METHOD: Intensive care unit nurses (n = 370) were recruited from 16 hospitals chosen by stratified sampling across Taipei County in Taiwan. Data were collected on nurses' knowledge of pain management using the Nurses' Knowledge and Attitudes Survey-Taiwanese version, on perceived barriers to pain management using a researcher-developed scale and on background information. RESULTS: The overall average correct response rate for the knowledge scale was 53.4%, indicating poor knowledge of pain management. The top barrier to managing pain identified by these nurses was 'giving proper pain prescription needs doctor's approval; can't depend on me'. Knowledge of pain management was significantly and negatively related to perceived barriers to pain management. In addition, scores for knowledge and perceived barriers differed significantly by specific intensive care unit. Knowledge also differed significantly by nurses' education level, clinical competence level (nursing ladder) and hospital accreditation category. CONCLUSION: Our results indicate an urgent need to strengthen pain education by including case analysis for intensive care nurses in Taiwan. RELEVANCE TO CLINICAL PRACTICE: Pain education should target knowledge deficits and barriers to changing pain management approaches for Taiwanese nurses in intensive care units.

Hepatitis B immunity in adolescents and necessity for boost vaccination: 23 years after nationwide hepatitis B virus vaccination program in Taiwan.

The first universal hepatitis B vaccination program for newborns in the world was launched in Taiwan in July 1984. Most studies on the effectiveness of hepatitis B vaccination focused on the seroprevalence of HBs Ag among children under 14 years old. Only few studies focused on the seropositivity of anti-HBs among adolescents aged 15-18 years old. The present study aimed to evaluate the impact of the nationwide hepatitis B vaccination program on the immunity to HBV infection and the necessity of boost among adolescents. In this study including eight annual seroprevalence surveys from 2000 to 2007, 2342 college entrants (1589 15-year-olds in group I and 753 18-year-olds in group II) and 1851 university freshmen (18-year-olds in group III) participated. Subjects identified anti-HBs, HBs Ag and anti-HBc negative were given boost three doses of HBV vaccine. The HBs Ag seroprevalence was 11.6%, 3.5% and 1.0% for participants who were born before 1984, 1984-1986 and after 1986. The anti-HBs-seropositive rates were significantly higher in group II (83.1%) than in group I (53.0%) and group III (53.5%). All 572 participants who were seronegative for anti-HBs, HBs Ag and anti-HBc became anti-HBs-seropositive after catch-up vaccination. It is concluded that the anti-HBs-seropositive rate decreased to 50% in 15 years after vaccination, and boost vaccination was 100% effective. The necessity and age for boost among anti-HBs negative adolescents and the timing of the first immunization should be further evaluated.

Prevalence of obesity and its association with cardiovascular disease risk factors in adolescent girls from a college in central Taiwan.

Although obesity is associated with important hemodynamic disturbances, little data exists on population-wide cardiovascular risk factors in obese adolescent girls in Taiwan. This study measured the prevalence of overweight/obesity and related cardiovascular disease risk factors in adolescent females. This was a school-based survey of a representative sample of 291 females aged 15 and 18 years in a public college in Central Taiwan. The main measures were height, body weight, systolic (SBP) and diastolic blood pressure (DBP), uric acid, cholesterol, triglyceride (TG) and high-density lipoprotein cholesterol (HDL-C). Obese (body mass index [BMI] > or = 25.3) and overweight (22.7 < or = BMI < or = 25.2) individuals were combined and labeled as overweight (BMI > or = 22.7) to make communication of results clearer. Data gleaned from freshmens health examinations were analyzed. The prevalence of obesity (BMI > or = 25.3) was 9.28% and of overweight (BMI > or = 22.7) was 21.31%. Being overweight was associated with higher SBP, DBP, uric acid and TG, and lower levels of HDL-C, but was not associated with cholesterol. The 15-year-old group showed higher mean levels of uric acid, total cholesterol, TG and HDL-C than the 18-year-old group (p < 0.05). All told, 3.1%, 15.12% and 2.1% of the girls showed abnormally elevated levels of uric acid, cholesterol and TG, respectively. In addition, 5.84% had abnormally lower HDL-C levels, indicating that interventions should focus on reducing obesity and encouraging proper dietary habits and sufficient exercise, especially in subjects with lower HDL-C levels and higher levels of cholesterol, TG and uric acid.
