S A case-control study of baldness in relation to myocardial infarction in men. Received for publication March 15, 2002; accepted for publication August 28, 2002. Kligman Lesko  NAHowell C) social science concerned chiefly with how people choose among alternatives. Three cohort studies have found an association of MPB and CHD risk. Hair pattern classification and frequency among participants in the Physicians' Health Study.  JMCarpenter The statement that the minimum wage needs to be increased is a: The existence of alternative uses for a resource implies it isn't scarce. Retrospective cohort study among 22,071 US male physicians aged 40 to 84 years enrolled in the Physicians' Health Study. A ‘J curve’ relationship was observed between body mass index (BMI) and risk of HF with maximum risk in the morbidly obese (1.73 (95% CI 1.30 to 2.31), p<0.001, n=11).  WJ Physiologic testosterone levels in normal men suppress high-density lipoprotein cholesterol levels. In contrast, our data indicate an association between vertex baldness and CHD in young and older men, as well as an association between severity of hair loss and increasing risk of CHD. D) the value of the best alternative forgone in making any choice. This study was supported by grants HL26490, HL34595, CA34944, and CA40360 from the National Institutes of Health, Bethesda, Md. Our prevalence ratio, considering whether diabetes is a risk factor for coronary heart disease is 12.04 / 3.9 = 3.1. Frontal baldness was a significant indicator of risk only among the subgroup of hypertensive participants (RR, 1.75; 95% CI, 1.24-2.48). Schnohr Multivariate adjustment for age, parental history of MI, height, body mass index (weight in kilograms divided by the square of the height in meters as a continuous variable), smoking, history of hypertension, diabetes, high cholesterol level, physical activity, and alcohol intake did not materially alter these associations. Reckelhoff Vertex pattern baldness appears to be a marker for increased risk of CHD events, especially among men with hypertension or high cholesterol levels. As shown in Figure 1, 57.3% of participants reported hair loss at age 45, with one third having some degree of vertex baldness. Consequently it is possible that we could learn more about pathogenesis of coronary heart disease by investigating possible genetic and environmental factors that determine aging, includ- ing premature … Glazer  JESatterfield For each RR, we calculated the 95% CI and performed a test for linear trend according to hair-pattern category. Hennekens  SMRosenberg Crofton  RSHalushka Beard growth was considered a useful bioassay marker for androgen activity more than 40 years ago (1). During 11 years of follow-up, we documented 1446 CHD events in this cohort. Our findings also extend the age range in which MPB serves as a marker for CHD and expand the range of outcomes to include angina and coronary revascularization as well as MI. While noting that more research needs to be done, one hypothesis that Dr. Margaret offers is that higher testosterone levels might be triggering both the hair loss and the heart disease.  DEStampfer  AObhrai An attempt should always be made to maximize opportunity cost. Coronary heart disease risk factors in women with polycystic ovary syndrome. In addition, the self-report of baldness pattern by questionnaire (Figure 1) was not internally validated and may have been a source of misclassification.  EAWhiting Kaufman Küster Animals that are given testosterone develop enlarged hearts. Herrera  BDKaplan The observed correlation between baldness and heart disease demonstrates that: A) being bald causes a man to have heart disease. Like other muscles, cardiac cells have receptors that bind male hormones. Between July 1, 1986, and June 30, 1996, the incidence rates of CHD-related events were assessed in the 71 617 women aged 40 to 65 years who answered these questions and were not diagnosed as having cardiovascular disease or cancer in 1986 (the baseline year for these analyses). When the end points of nonfatal MI, angina, and coronary revascularization were considered separately, similar results were obtained for each outcome (Table 3).  MJCelermajer  IMorita As life expectancies increase, signs of …  HC The studies have found that bald -headed men are 32 percent more predisposed to suffer from heart trouble than full-headed men. The existence of alternative uses of a resource implies that it is: The problem of scarcity is confronted by: A(n) _______ does not pose the problem of scarcity; one use of the good is not an alternative to another use.  MJensen Manson  MLDavis  ESFreedman The observed association was independent of age and was stronger in a subgroup of men with hypertension or high cholesterol.  et al.  AERandal  CJKnopp The Case in Point on "baldness and heart disease" suggests that by preventing baldness: here is probably some other factor that causes both baldness and heart disease. Describe in economics there are few absolute solutions. C) an increase in investment spending tends to reduce unemployment.  JTShare Get the latest from JAMA Internal Medicine. The fallacy of false cause is committed when a person mistakenly assumes that one event causes another because the first event precedes the second. To examine the association between male pattern baldness and the risk of coronary heart disease (CHD) events. C) bald men are generally unreliable. We did not have data about hair pattern in those participants who died before the 11-year follow-up (n = 1777), of whom approximately one third died from cardiovascular disease.11 The data about hair pattern at age 45 years were obtained on the 11-year questionnaire, at which time the physicians were aged 51 to 95 years.  V Baldness and coronary heart disease risk factors.  PNyboe 7.  RMorimoto The opportunity cost of going to a movie is: D) the next best use of the time and the money spent. Significant between-hospital variation (up to ninefold) in adjusted cost was observed across operations. One question that arises when determining for whom goods and services should be produced is: A) Who gets how much of the economic pie? Moreover, random misclassification would have led to an underestimate of the magnitude of association between baldness pattern and CHD. When we are forced to make choices we are facing the concept of: A) a choice must be made among two or more alternatives.  RJAdams  PJ Nuclear uptake of sex steroid hormones in the cardiovascular system of the baboon. In Figure 5, we demonstrate that there is a strong correlation between the baseline explant and autopsy hearts compared to their later timepoints (Pearson's correlation ranges from 0.92-0.98).  RHVale with reference to the 5 diagrams pictured above. Male Baldness and Heart Disease.  A Expression of adrenal cytocromes P-450 in testosterone-induced hypertension.  G Gray hair, baldness, and wrinkles in relation to myocardial infarction: the Copenhagen City Heart Study.  DW Factors discriminating men with coronary heart disease from healthy controls. In 1979, Cooke studied the prevalence of male pattern alopecia, CAD, hypertension, and smoking habits in 478 male Caucasian hospital inpatients over the age of 20 years. B) bald men are generally unreliable. Both baldness and cardiovascular disease share the common risk factor of ageing and with the demographic shift towards ageing populations that is occurring in both developed and undeveloped countries, it is expected that chronic and age-related diseases such as ischaemic heart disease, already the leading cause of death in the world will contribute a higher proportion to the overall disease burden , .  PV Testosterone increases thromboxane A2 receptor density and responsiveness in rat aortas and platelets.  DBurton  JEGrobbee The problem of determining for whom to produce exists because: B) a decision that one person or group will receive a good or service usually means that another person or group will not. After adjusting for age and treatment assignment, we calculated relative risks (RRs) and 95% confidence intervals (CIs) for the occurrence of CHD events associated with categories of MPB using conditional logistic regression models. Our data are compatible with these findings for hypertension and high cholesterol levels, but we detected no modifying effect by parental history of MI. Although early vertex baldness may be a nonmodifiable risk factor for CHD, it may serve as a useful clinical marker to identify men at increased risk who may benefit from aggressive screening and primary prevention efforts directed toward other known modifiable risk factors for CHD. In addition, the location of hair loss (frontal vs vertex) was not assessed, and the study's statistical power was limited.  DSByers  D Inheritance of baldness.  GJeans  MSClayton Govind A direct association between testosterone and heart disease has never been established, but for many years, doctors have suspected that a link exists. © 2020 American Medical Association.  L Gonadal hormones modulate deoxycorticosterone-salt hypertension in male and female rats.  PV Testosterone increases human platelet thromboxane A2 receptor density and aggregation responses. In simple terms, bald men face a greater risk of contracting heart conditions compared to those men with full head of hair. Ford Medical researchers followed 1435 middle-aged men for a period of 5 years, measuring the amount of Baldness present   Home » Questions » Computer Science » Database Management System » Database Management System - Others » Baldness and heart disease. angioplasty, … Conclusion  In a case-control study, vertex baldness was associated with myocardial infarction (MI) among men younger than 55 years but frontal baldness was not.7 The Copenhagen City Heart Study8 showed a significant association between frontal baldness and MI independent of age, while the observed association with vertex baldness was of borderline significance.  HC Participants with severe vertex baldness reported a higher prevalence of diabetes than men classified in other hair-pattern categories. Vertex pattern baldness appears to be a marker for increased risk of CHD events, especially among men with hypertension or high cholesterol levels.  JE In looking at secondary quality of care outcomes, the authors found that overall, "there was no consistent relationship observed with physician payment." If you conclude that the six o'clock business report makes the sun set, you are guilty of the fallacy of: The Case in Point on "baldness and heart disease" suggests that by preventing baldness: B) men are unlikely to influence their chances of having heart problems.  CHBuring Male pattern baldness was first defined as an autosomal dominant trait 80 years ago,31 although recent studies suggest a polygenic mode of inheritance.32 Recent findings suggest genetic similarities between MPB and polycystic ovary syndrome,33,34 a common familial condition in women characterized by elevated levels of androgens.  JP Testosterone exacerbates hypertension and reduces pressure-natriuresis in male spontaneously hypertensive rats. Carey High levels of bilirubin are associated with decreased risk of coronary heart disease (CHD) and cardiovascular disease (CVD) [ 1 ]. Copenhagen, Denmark Regional Office for Europe, World Health Organization April26-29 1971; Norwood  RG Heart contains receptors for dihydrotestosterone but not testosterone: possible role in the sex differential in coronary heart disease.  KRuff  RHalushka The reasoning goes like this: men have much more testosterone than women, and they develop heart disease about 10 years before their female counterparts.  JrAufdemorte  RGHolt They also asked a control group (not suffering from heart disease) of 772 males to do the same baldness assessment. The observed correlation between baldness and heart disease demonstrates that: A) there is probably some other factor that causes both baldness and heart disease.  DClerici It was first identified by McCully in 1969. High levels of androgens may directly contribute to both atherosclerosis and thrombosis, and may adversely influence risk factors such as hypertension and high cholesterol. Vertex baldness was more strongly associated with CHD risk among men with hypertension (multivariate RR, 1.79; 95% CI, 1.31-2.44) or high cholesterol levels (multivariate RR, 2.78; 95% CI, 1.09-7.12). Microeconomics deals with: A) the working of the entire economy or large sectors of it.  MJ  BBBosco Guzick Cardiovascular risk factors activate a number o… After the researchers made adjustments for age and other cardiovascular disease risk factors, they concluded that male pattern baldness can put men at a 5.6 times higher risk of developing heart disease. However, controlling for parental history of premature coronary disease did not materially alter the association between MPB and CHD risk in our data. The prevalence of coronary heart disease among people without diabetes is 91 divided by 2340, or 3.9% of all people with diabetes have coronary heart disease. Answer to Baldness and heart disease again Refer back to Exercise 13.  MR  TBTriplett Customize your JAMA Network experience by selecting one or more topics from the list below. The endothelium constitutes the largest organ system in the body. Making choices that are expected to achieve the highest possible value for some objective is termed: The economic way of thinking has to do with: The BEST example of making a choice at the margin is: C) a coffee drinker drinking another cup of coffee.  DSTalbott  MMMeyrick The previous study found that, compared with men with no hair loss, men with frontal baldness had a 9% increased risk for heart conditions and those with vertex baldness had a 23% increased risk.  MBrownie  AAMathur However, the absolute number of bald areas was not associated with risk of CHD.  JAppleyard Although the baseline prevalence of these risk factors was only slightly higher in men with hair loss, a possible link between baldness and these risk factors was suggested in the Olivetti Heart Study in Naples, Italy,15 in which 872 men underwent measurements of blood pressure levels, serum cholesterol levels, and direct examinations of the scalp, with hair pattern coded as no hair loss, frontal hair loss, and frontal-occipital hair loss. The study, involving a random sample of 20,000 men and women in the Copenhagen City Heart Study, recorded the extent of baldness, gray hair, wrinkles and a … All statistical analyses were performed using SAS software, with 2-tailed P values of <.05 considered significant. Recall bias is unlikely but cannot be excluded, as physicians may be aware of a possible association between MPB and CHD risk. On the 11-year follow-up questionnaire, participants were asked "Which of the following most closely approximates your hair pattern at age 45?" After controlling for age and treatment assignment, MPB was associated with a modest increase in risk of CHD events (Table 2).  Jr Carotid atherosclerosis in women with polycystic ovary syndrome: initial results from a case-control study.  JEBremner Trevisan “Endothelial function” refers to a multitude of physiological functions of the vascular endothelium that are achieved via secretion of diverse bioactive substances. Men with rapid hair loss (n = 34) during the 5-year interval had a relative risk of CHD of 2.4 (95% CI, 1.3-4.4) when compared with those who had no or slight progression of baldness (n = 224).  EKrogh There is growing evidence that indicates an association between male-type baldness and coronary artery disease (CAD) 5. A term that means "all other things unchanged" is: The use of controlled experiments using particular substances to test hypotheses is most likely to be found in: Reaching the incorrect conclusion that one event causes another because the events tend to occur together is called: The incorrect presumption that because two events tend to occur together, one must cause the other is the: A person who mistakenly assumes that because one event follows another, the second event results from the first commits the fallacy of: Suppose you observe that the sun sets every evening after the six o'clock business report. Lotufo PA, Chae CU, Ajani UA, Hennekens CH, Manson JE. Compared with men with no hair loss, those with frontal baldness had an age-adjusted relative risk (RR) of CHD of 1.09 (95% confidence interval [CI], 0.94-1.25), while those with mild, moderate, or severe vertex baldness had RRs of 1.23 (95% CI, 1.05-1.43), 1.32 (95% CI, 1.10-1.59), and 1.36 (95% CI, 1.11-1.67), respectively (.  et al. Water is considered a scarce good rather than a free good because: The problem of determining what goods and services society should produce exists because: A free good is different from a scarce good because it is: The statement that "there is no such thing as a free lunch" means: B) any production requires the use of scarce resources, and thus the sacrifice of another alternative. Setty  JEManson A key theme fundamental to all of economics is: C) people have unlimited wants facing limited means to satisfy them. Men who experienced premature greying had a 5.3 times greater risk. Main Outcome Measures   AM The comparative histopathology of male pattern baldness and senescent baldness. A more likely explanation for the association between baldness and heart disease is that both conditions are affected by an underlying factor. The respondents answered the question, "Which of the following most closely approximates your hair pattern at age 45?" In NHANES I,6 a subgroup of participants (n = 3932) was examined according to the presence and degree of baldness measured by dermatologic examination. This statement: Many disagreements among economists result because: B) economists sometimes make normative judgments.  RBGerstman  SMRobinson For our primary analyses, we used a combined end point of the first reported CHD event (n = 1446). We detected no effect modification when we performed analyses stratified by age (older and younger than 55 years at baseline).  SK As a comparison, the Pearson's correlation(r), between … Baldness was assessed in 1956 and 1962 in a cohort of 2017 men observed for 24 years for new CHD events, cardiovascular events, CHD, and all-cause mortality.  WHapple Herman Paulo A.

These lipid alterations are most likely due to decreased androgen levels because they are reversed by administration of the gonadotropin-releasing hormone antagonist together with testosterone.29. The correlation between hyperhomocysteinemia and atherosclerotic disease was first proposed more than 40 years ago.  AMorinelli Finally, because 92.1% of the PHS participants were white, our results may not be generalizable to men of other racial groups in whom baldness pattern frequency37 and risk of CHD may differ.38 In summary, however, our study provides support for the hypothesis that vertex pattern baldness is a marker for increased risk of CHD events.  LR Hair pattern of the scalp of white and Negro males. We also examined types of CHD events separately. Economists pay special attention to making choices at the margin. Those with near-complete baldness had a 36% increase in risk for heart conditions (nonfatal heart attack or angina, procedures to open blocked coronary arteries (e.g.  WLesko  LABelanger All Rights Reserved, Challenges in Clinical Electrocardiography, Clinical Implications of Basic Neuroscience, Health Care Economics, Insurance, Payment, Scientific Discovery and the Future of Medicine, United States Preventive Services Task Force, 2000;160(2):165-171. doi:10.1001/archinte.160.2.165. The value of the next-best choice not chosen is called opportunity cost.  ESugimoto Several potential limitations of our study warrant discussion. to download free article PDFs, A positive association was found between the frontal-occipital baldness pattern and both diastolic blood pressure and high cholesterol level. The Physicians' Health Study (PHS) of 22,071 apparently healthy men at baseline provided a unique opportunity to evaluate whether different patterns of male baldness at age 45 years were associated with future risk of coronary events, including nonfatal MI, angina, and coronary revascularization. Finasteride in the treatment of men with androgenetic alopecia: Finasteride Male Pattern Hair Loss Study Group.  JL Myocardial infarction, androgen and the skin. Fujimoto No association was shown between CAD and either male pattern alopecia, premature male pattern alopecia, or male pattern alopecia … C) emphasis on how choices are made at the margin.  KLShort Sheikh Our website uses cookies to enhance your experience. Aspirin in the primary prevention of angina pectoris in a randomized trial of United States physicians. In a subgroup analysis, we examined possible modifiers of the association between baldness pattern and CHD risk by cardiovascular risk factor status (Table 4). Get free access to newly published articles. The answer to, "What goods are to be produced?" The fundamental economic questions that every economic system must answer are: a. what, how, and for whom. A) concerned with developing theories and interested in solving problems. Persson © 2020 American Medical Association. The strength of the association was not materially altered in multivariate analyses after controlling for multiple potential confounders.  AHChan 2000;160(2):165–171.  A The Copenhagen Heart Study8 observed 5837 men over 12 years and assessed 2 types of baldness, frontoparietal and crown-top, both of which were associated with CHD. All Rights Reserved. determines: C) how resources are combined in the production of goods. We chose to assess hair loss at age 45 years to differentiate those men with early, androgen-dependent balding from those with senescent baldness, which is more common after age 50.14. The study of how people choose among the alternatives available to them is the: According to the textbook, economics is a: A) social science that deals with making choices among alternatives. Vertex baldness was more strongly associated with CHD risk in the subgroup of men with hypertension (RR, 1.79; 95% CI, 1.31-2.44) or high cholesterol levels (RR, 2.78; 95% CI, 1.09-7.12) than in men without these risk factors. Cooke  MRBoyer In the Framingham Heart Study,5 the extent (defined as the number of bald areas) and progression of hair loss were analyzed in relation to risk of CHD.

Compared with men with no hair loss, those with frontal baldness had a relative risk of CHD of 1.09 (95% CI, 0.94-1.25), while those with mild, moderate, or severe vertex baldness had relative risks of CHD of 1.23 (95% CI, 1.05-1.43), 1.32 (95% CI, 1.10-1.59), and 1.36 (95% CI, 1.11-1.67), respectively (P for linear trend <.001). Statements that are a hypothesis or statement of fact are: A) The rate of unemployment is 4 percent. Comment on their conclusion that this shows that baldness is not a possible cause of heart disease. An answer to the question "For whom" determines: D) who gets the goods and services produced.  WWRivier Sheridan Economics, generally speaking, is primarily concerned with: C) how people choose among the alternatives available to them. A hypothesis that has been tested extensively without being rejected and has won widespread acceptance is a: A theory that has won virtually universal acceptance is a: A simplified representation of a particular problem is a: A) model. Similarly the prevalence among those with diabetes is 12.04%.  T Baldness and ischemic heart disease in a national sample of men. EPIDEMIOLOGIC studies examining male pattern baldness (MPB) and coronary heart disease (CHD) have tended to support a positive association.  SHennekens Of the 22,071 randomized subjects in the PHS, 20,294 were alive at the 11-year follow-up. From the Division of Preventive Medicine, Department of Medicine, Harvard Medical School and Brigham and Women's Hospital (Drs Lotufo, Chae, Ajani, Hennekens, and Manson), the Cardiology Division, Massachusetts General Hospital (Dr Chae), and the Department of Epidemiology, Harvard School of Public Health (Drs Hennekens and Manson), Boston, Mass. Whenever a choice is made: A) the value of all the other choices that could have been made is called opportunity cost. Statements that make value judgments are: B) A high rate of economic growth is good for the country.  JMCohen Gallant In a systematic review of observational studies of anabolic steroid use, androgen administration was associated with lower levels of high-density lipoprotein (HDL) cholesterol and higher total-HDL cholesterol ratios.28 Induction of experimental hypogonadism with a gonadotropin-releasing hormone antagonist (Nal-Glu) for 6 weeks increased HDL levels by 26% and total cholesterol levels by 12% among healthy young men.
