Are there differences in oral health and oral health behavior between individuals with high and low dental fear?

Epidemiological studies of the relationship between dental fear, use of dental services, and oral health in different age groups in a common population are scarce. Dental fear and its relationships are usually described in individuals with high dental fear only. The purposes of this study were to describe the prevalence of dental fear in the...

A prospective study on active and environmental tobacco smoking and bladder cancer risk (The Netherlands)

Objective: In a prospective cohort study among 120,852 adult subjects the authors investigated the associations between cigarette, cigar, pipe, environmental tobacco smoking (ETS), and bladder cancer. Methods: In 1986 all subjects completed a questionnaire on cancer risk factors. Follow-up for incident bladder cancer was established by linkage...

Vegetable and fruit consumption and lung cancer risk in the Netherlands: Cohort study on diet and cancer

Objective: The purpose was to study the association between vegetable and fruit consumption and lung cancer incidence using 1074 cases after 6.3 years of follow-up in the Netherlands Cohort Study. Methods: Dietary intake was assessed using a 150-item food-frequency questionnaire. Multivariate models were used including age, sex, family history...

Self-reported physical disabilities in children in the Netherlands

Purpose: To assess the prevalence of self-reported physical disabilities in school children, through the Child Health Monitoring System. Methods: In 1992/1993, data were obtained in mainstream education (n = 5484), and in 1994/1995 in special education (n = 2622). The data were weighted to calculate estimates representative of the Dutch...

Vegetable and fruit consumption and risks of colon and rectal cancer in a prospective cohort study

The relation between vegetable and fruit consumption and colorectal cancer risk was comprehensively assessed in the Netherlands Cohort Study on Diet and Cancer using a validated 150-item food frequency questionnaire. After 6.3 years of follow-up (1986-1992), over 1,000 incident cases of colorectal cancer were registered. Using case-cohort...

Additional risk factors influence excess mortality in heterozygous familial hypercholesterolaemia

Life expectancy of patients with familial hypercholesterolaemia is decreased. Some untreated patients reach a normal life span and, therefore, additional risk factors and the type of mutation in the low-density lipoprotein (LDL) receptor gene are likely to influence the clinical outcome. We determined all cause mortality in kindreds with the...

Arterial stiffness as underlying mechanism of disagreement between an oscillometric blood pressure monitor and a sphygmomanometer

Oscillometric blood pressure devices tend to overestimate systolic blood pressure and underestimate diastolic blood pressure compared with sphygmomanometers. Recent studies indicate that discrepancies in performance between these devices may differ between healthy and diabetic subjects. Arterial stiffness in diabetics could be the underlying...

Does the risk of childhood diabetes mellitus require revision of the guideline values for nitrate in drinking water?

In recent years, several studies have addressed a possible relationship between nitrate exposure and childhood type 1 insulin-dependent diabetes mellitus. The present ecologic study describes a possible relation between the incidence of type 1 diabetes and nitrate levels in drinking water in The Netherlands, and evaluates whether the World...

Vegetable and fruit consumption and prostate cancer risk: A cohort study in the Netherlands

The association between 21 vegetables and eight fruits and prostate cancer risk was assessed in the Netherlands Cohort Study among 58,279 men of ages 55-69 years at baseline in 1986. After 6.3 years of follow-up, 610 cases with complete vegetable data and 642 cases with complete fruit data were available for analysis. In multivariate case-cohort...

The impact of individual and area characteristics on urban socioeconomic differences in health and smoking

Background. In general, poor health and lifestyles occur more frequently among individuals of low socioeconomic status (SES) and in deprived areas. An explanation for the latter may simply be the on average lower SES of residents of these areas. It is possible, however, that living in a deprived area contributes to poor health and lifestyles....

Surveillance of acute flaccid paralysis in the Netherlands, 1992-94

Detection and investigation of call cases of acute flaccid paralysis (AFP) in children below 15 years of age are among the criteria for poliomyelitis-free certification. In the absence of poliomyelitis the incidence of AFP is around 1 per 100 000 children aged < 15 years. In the Netherlands, surveillance of AFP began in October 1992 under the...

Blood pressure and mortality in elderly people aged 85 and older: Community based study

Objective: To determine whether the inverse relation between blood pressure and all cause mortality in elderly people over 85 years of age can be explained by adjusting for health status, and to determine whether high blood pressure is a risk factor for mortality when the effects of poor health are accounted for. Design: 5 to 7 year follow up of...

Surveillance of acute flaccid paralysis in the Netherlands, 1992-94

Genetic analysis of sex and generation differences in plasma lipid, lipoprotein, and apolipoprotein levels in adolescent twins and their parents

In a sample of Dutch families consisting of parents aged 35-65 years and their twin offspring aged 14-21 years, a significant difference between generations was observed in phenotypic variances and in genetic heritabilities for plasma levels of total cholesterol, triglycerides, high density lipoprotein (HDL) and low density lipoprotein (LDL)...

A prospective cohort study on the relationship between onion and leek consumption, garlic supplement use and the risk of colorectal carcinoma in the Netherlands

The association between onion and leek consumption, garlic supplement use and colon and rectum carcinoma among men and women was evaluated in the Netherlands Cohort Study, a large-scale prospective cohort study on diet and cancer. Onions, leeks, and garlic belong to the Allium genus and contain large amounts of potentially chemopreventive...

Epidemiologie van tandcariës in Nederland [Epidemiology of dental caries in the Netherlands]

Both in 6- and 12-year-old Dutch children the prevalence of dental caries has declined remarkably between 1970 and 1985. However, in 6-year-olds the decline terminated after that period, while it continued in the 12-year-olds. In 1986 a national dental survey of the caries prevalence of older age categories was executed. As no comparable caries...
