In order to establish basic epidemiological data on chronic pain (duration > 3 months) in a rural population, a survey of pain symptoms was conducted by means of a postal questionnaire. The questionnaire was sent to a random sample (from the population register) of 15% of the population aged 25-74 (n = 1806) in two Swedish primary health care districts. The response rate was 90%. In a follow-up study individuals selected among the responders (neck-shoulder pain, widespread pain and controls without pain; n = 213) were examined and interviewed. They were requestioned about pain symptoms 24 months after the initial survey. Without sex differences 55% of the population had perceived persistent pain for 3 months and 49% for 6 months. Women experienced more multiple localizations of pain and had pain in neck, shoulder, arm and thigh to a greater extent than men. Prevalence of pain increased by age up to 50-59 years for both genders and then slowly decreased. The neck-shoulder area was the most common site of pain (women 32.9%, men 27.5%). Blue-collar workers and employers (including farmers) reported chronic pain to a greater extent than other groups. In 13% of the population, manifest pain problems were associated with reduced functional capacity. Examination of selected pain groups indicated a high proportion of unspecific musculoskeletal symptoms. Diagnosis with definite definitions, explaining the pains, were found in 40% of the individuals. Individuals with widespread pain had a higher pain intensity, more somatic symptoms, were more depressive and had the lowest scores for quality of life.(ABSTRACT TRUNCATED AT 250 WORDS)
Dietary intake as initially estimated by means of a 24-h recall has been related to the incidence of ischemic heart disease, stroke, and overall mortality during a 12-yr follow-up period in a prospective study of 1462 women representative of the general population. Energy intake was inversely correlated to the 12-yr incidence of myocardial infarction. The correlation was independent of age, indices of obesity, smoking habits, serum cholesterol, serum triglycerides, diabetes, systolic blood pressure, and physical activity. No correlation was found between dietary intake and incidence of stroke or overall mortality, nor was any correlation found between end-points and intake of fish, energy percentage of fat, protein, and carbohydrates. These observations suggest that suboptimal intake of nutrients may be an important factor in the pathogenesis of ischemic heart disease.
Background. Retrospective studies of familial cancer risks could be subjected to bias and should be supplemented with prospective studies if possible. Few such studies exist, and no prospective population‐based study has addressed the risk for malignant tumors among relatives or wives of men with breast cancer. Methods. All first‐degree relatives and wives of 153 men whose conditions were diagnosed as male breast cancer from 1965 to 1989 in the southern health‐care region of Sweden were identified through parish data. Relatives and wives alive January 1, 1958, were included in two cohorts. Their vital status and cancer morbidity were studied in the Swedish Cancer Registry, Cause of Death Registry, and Census Registry. Results. The incidence for malignant tumors was significantly increased among female first‐degree relatives (standardized morbidity ratio [SMR], 1.36). Significantly elevated SMR were seen for breast carcinoma (SMR, 1.80), ovarian carcinoma (SMR, 2.27), and cancer of the parotid gland (SMR, 5.58). Elevated nonsignificant SMR were seen for cancer of the cervix uteri and for bone and soft tissue sarcoma. An almost significant decreased overall cancer incidence was seen for male first‐degree relatives (SMR, 0.75). The most pronounced decrease was seen for cancer of the prostate. The increased breast cancer incidence in female relatives were present in mothers, sisters, and daughters. The overall tumor incidence was not increased (SMR, 0.98) in wives of men with breast cancer. There was no significant increase in breast cancer incidence (SMR, 0.97). Conclusions. Female first‐degree relatives of men with breast cancer have an elevated incidence of breast cancer and other female genital tumors, whereas male first‐degree relatives have a reduced cancer incidence. Wives of men with breast cancer have a similar cancer incidence as the general population.
In 1997 John Broome presented the Collapsing Argument that was meant to establish that non‐conventional comparative relations (e.g., “parity,” “imprecise equality,” “incommensurability”) cannot exist. Broome's argument has faced a lot of scrutiny and a certain type of counterexample has been used to undermine it. Most of the counterexamples focus on the Collapsing Principle which plays a central role in Broome's argument. In this article we will take a closer look at the most common type of counterexample and propose how to adjust the Collapsing Principle in order to avoid objections based on these counterexamples. We argue that a weaker version of the Collapsing Principle is not susceptible to the classical counterexamples. Furthermore, after an explorative discussion about the intuitions behind the original principle, we show that this weaker formulation is at least as intuitive as the principle suggested by Broome.
According to Ruth Chang the three standard positive value relations: Bbetter than^, Bworse than^and Bequally good^do not fully exhaust the conceptual space for positive value relations. According to her, there is room for a fourth positive value relation, which she calls Bparity^. Her argument for parity comes in three parts. First, she argues that there are items that are not related by the standard three value relations. Second, that these items are not incomparable, and third, that the phenomena she has focused on are not due to the vagueness of the comparative predicates (i.e., that it is indeterminate which of the standard value relations that holds). This paper focuses on the second part of the argument and an objection is presented. By assuming the Small Unidimensional Difference Principle, which is a key premise for the second part of the argument, Chang's argument could be accused of begging the question. More so, by assuming this principle, the space for incomparability gets severely limited. If these worries are justified, then Chang's argument for parity as a fourth form of comparability is unsuccessful.
