| worksite health screening programs for predicting the development of metabolic syndrome in middle-aged employees: a five-year follow-up study. | metabolic syndrome (mets) management programs conventionally focus on the adults having mets. however, risk assessment for mets development is also important for many adults potentially at risk but do not yet fulfill mets criteria at screening. therefore, we conducted this follow-up study to explore whether initial screening records can be efficiently applied on the prediction of the mets occurrence in healthy middle-aged employees. | 2010 | 21126351 |
| association between seropositivity of antibodies against hepatitis a virus and helicobacter pylori. | helicobacter pylori and hepatitis a virus (hav) are documented to share common transmission routes including fecal-oral. this study examined the association between seropositivity of antibodies against h. pylori (anti-hp) and hav (anti-hav) via a community-based survey of 40 randomly selected kindergartens in 10 urban and 10 rural areas. serum samples from 2,047 healthy preschool children and 104 teachers were screened for anti-hp by enzyme-linked immunosorbent assay, and for anti-hav by micropa ... | 2000 | 11388513 |
| immunogenicity and safety of an inactivated hepatitis a vaccine in taiwanese adults and children. | the safety and immunogenicity of an inactivated hepatitis a vaccine (avaxim, 160 antigen units) was evaluated in 190 subjects: 50 children aged from 2 to 5 years, 70 children aged from 6 to 17 years and 70 adults aged from 18 to 30 years in a monocentric, open, non-controlled, phase iii trial conducted in taipei, taiwan from december 1996 to october 1997. the vaccine was administered intramuscularly, with a two-dose schedule 6 months apart. clinical adverse events were monitored during the seven ... | 2000 | 11023061 |
| current seroprevalence of hepatitis a virus infection among kindergarten children and teachers in taiwan. | taiwan was a hyperendemic area for hepatitis a virus (hav) infection before the late 1980s. the seroprevalence of hav infection was higher than 90% with most hav infection occurring during childhood. this study was to estimate the seroprevalence of hav infection among preschool children in central taiwan. a community-based survey was carried out in 54 kindergartens in 10 urban areas, 10 rural areas and 2 aboriginal areas randomly selected through stratified sampling. serum samples of 2,549 healt ... | 2000 | 11023060 |
| a two dose combined hepatitis a and b vaccine in chinese youngsters. | this open, randomized study was conducted in healthy chinese youngsters, aged between 10 and 19 years to compare the reactogenicity and immunogenicity of two vaccines: the combined vaccine against hepatitis a and b was administered in a two-dose schedule with the profile of the corresponding monovalent vaccines, while the concomitant vaccine was administered also on a two-dose schedule but simultaneously in opposite arms. all vaccinees had antibodies against hepatitis a (anti-hav) after the 2-do ... | 1999 | 10440800 |

| hepatitis a virus infection in taiwan. a hospital-based study. | one hundred and thirty-four healthy subjects and 220 patients with liver diseases were studied for antibody to hepatitis a virus (anti-hav) with radio-immunoassay. the frequency of anti-hav related closely to the age of healthy subjects; the rate of positivity increased with age, being 5.9% in those under four years, 13.3% in the late first decade and over 90% after the third decade. taking meals at stalls with poor sanitary standards is suspected to cause the prevailing infection in teenagers, ... | 1980 | 6259786 |
| [prevalence of hepatitis virus infections in restaurant workers in taipei (author's transl)]. | hepatitis b surface antigen (hbsag) and anti-hepatitis a virus antibody (antihav) in sera or saliva of restaurant workers in chung shan district, taipei, were tested by radioimmunoassay from october 1978 to march 1979. among the 2006 serum samples 387 (19.3%) were hbsag positive. while significant difference between male and female restaurant workers was observed, no age difference was noted. the workers originated from taiwan demonstrated the highest frequency of hepatitis b antigenemia (20.9%) ... | 1980 | 6256133 |
| hepatitis viruses in southern taiwan--mass survey of 2985 inhabitants. | a survey of 2985 apparently healthy taiwanese in southern taiwan revealed a high prevalence (18.2%) of hepatitis b surface antigen (hbsag). it was significantly higher in males (22.3%) than in females (13.6%), but no correlation with family origin, socioeconomic status or residence was established. about one-third of the breeding female hbsag carriers were hbeag-positive, and these may be an important source in the spread of hbv. subtyping of hbsag in 63 subjects showed adw to be dominant in thi ... | 1984 | 6092191 |
| changing seroepidemiology of hepatitis a virus infection in taiwan. | hepatitis a antibody (anti-hav) in serum was studied from june to october, 1984, by radioimmunoassay in 647 male and 553 female apparently healthy children under 15 years of age in taipei city. the prevalence rate of anti-hav was 27.0% in infants, decreased to around 1% during the preschool age, then increased and remained around 5% until 11-12 years of age, when another increase was noted, and reached 13.6% among the early teenagers. the age-specific prevalence of anti-hav increased with age bu ... | 1985 | 3001219 |

| incidence of hepatitis a virus infection in children in taipei, taiwan. | to understand the prevalence and incidence of hepatitis a virus (hav) infection in chinese children in taiwan, we determined the age-specific prevalence of hepatitis a antibodies (anti-hav) in 823 children, ranging from birth (cord blood) to 19 years of age. the frequency of anti-hav rose with increasing age with three different slopes, probably reflecting different age-specific incidences: lowest under 4 years of age, intermediate between 4 and 10 years, and highest above 10 years. we obtained ... | 1983 | 6313545 |
