Psychosocial stressors associated with Mexican migrant farmworkers in the midwest United States

Although estimates suggest that there are upwards of 5 million migrant farmworkers in the United States, scant research has explored the stressors associated with their lifestyle. Contrary to previous work, the present study directly explored migrant farmworkers' own perceptions of what is difficult in their lives. The purposes of the present study were to qualitatively explore, from a phenomenological standpoint, the stressors associated with living as a migrant farmworker in the Midwest United States; and to determine the stressors that were most strongly related to symptoms of anxiety and depression. The findings indicated that 18 stressors were commonly experienced by the migrant farmworkers and that the farmworkers experienced overall elevated levels of anxiety and depression. A number of stressors that were not previously reported in the literature were identified. The stressors of rigid work demands and poor housing conditions were significantly associated with higher levels of anxiety and low family income/living in poverty and rigid work demands were significantly associated with depression. Implications of findings and prevention strategies are discussed.     

Levels of β-HCH,HCB, p,p′-DDE,p,p′-DDT and PCBs in human milk from a continental town in Croatia,Yugoslavia

Summary Concentrations of -HCH, HCB, p,p-DDE, p,p-DDT and PCBs were determined by gas chromatography in 50 human milk samples collected from the general population during 1981/1982 in a continental town in Croatia (Yugoslavia). The samples were collected between one and 22 weeks after delivery from mothers breast-feeding one child only. The mothers' age was 18 to 31 years, and they were nursing their first or second child. All 50 samples contained -HCH, HCB, p,p-DDE and PCBs, whereas p,p-DDT was present in 37 samples. The concentrations of -HCH, HCB, p,p-DDE, p,p-DDT and PCBs expressed on a whole milk basis were (median in g/kg): 11, 7.1, 67, 7.3 and 22 respectively, and expressed on a fat basis (median in mg/kg): 0.28, 0.21, 1.9, 0.18 and 0.62 respectively. The fat content was 3.7% (median). PCBs were present in a mixture containing penta-, hexa- and heptachlorobiphenyls.     

Correlation between vibration-induced white finger and symptoms of upper and lower extremities in vibration syndrome

Summary The correlation was investigated between the frequency of attacks of vibration-induced white finger (VWF) and numbness or coldness of the fingers and legs in patients with vibration syndrome. Some 1687 patients with vibration syndrome were examined and of these 342 chain-saw operators and 277 rock-drill operators had no disease other than vibration snydrome. Then subjects were matched by age and period of treatment within three years. In the last analysis, 20 in the VWF almost everyday group or in the never group, and 40 in the occasionally group were selected from the chain-saw operators, and from the rock-drill operators 32 in the VWF everyday or the never group and 64 in the occasionally group. The present study showed that, with the frequency of VWF attacks, patients had a higher prevalence of coldness not only in the fingers but also in the legs. These findings suggest a correlation between the severity of circulatory disturbances of the upper extremities and that of the lower ones in patients with vibration syndrome. Further studies on circulatory disturbances in the leg are required.     

The debate on primary prevention: Toward a synthesis

Conclusion The primary prevention model presented above provides a larger theoretical structure capable of including both sides of the debate. It encourages primary prevention efforts yet builds in the careful assessment, planning, research, and evaluation needed to prevent excesses.Primary prevention is an experiment. It is thezeitgeist in mental health, and it will have its day. It is a powerful metaphor spurred by the dream of eradicating mental illness from society. Primary prevention may prove to be an important turning point in the history of mental health. Or it may end up on the junk heap of progressive ideas which were either unsound or unworkable. Either way, primary prevention is an idea whose time has finally come.     

Making sense of illness: late-in-life migration as point of departure for elderly Iranian immigrants' explanatory models of illness

This article is based on data gathered through 60 qualitative interviews conducted within the realm of three research projects that have used culture-appropriate lenses to study the postmigration situation of late-in-life Iranian immigrants to Sweden. The findings gathered through these studies were interpreted against the backdrop that culturally appropriate nursing theories provide. This meant that it was, at times, these elders backgrounds as cultural others that were implicitly used to make sense of the various issues that were brought to the fore by these studies. The particular issue with which this article is concerned is the unusualness of these elders explanatory models of illness. Inspired by the concept definition of situation in the symbolic interactionist perspective and by the feeling that this perspective might bring about a different interpretation of the original findings regarding their understandings of illness and disease, we set out to conduct a secondary analysis of these elders explanatory models of illness. The findings presented in this article will show how the elderly Iranian immigrants interviewed in these three studies utilize the process of late in life migration as a point of reference for their understandings of what has caused the illnesses from which they suffered. Hereby we will suggest that the unusualness of their explanatory models of illness might be best understood if we focus on what they shared as immigrants (i.e., the fact that the process of late-in-life migration has made their culture obsolete) as opposed to what they shared as Iranians (i.e., their culture of origin).     

Primary prevention: Key issues and a competence perspective

At a superficial level, one might characterize the primary prevention debate as centering on the question of whether primary prevention has been demonstrated to be an effective means of promoting mental health. This interpretation is supported by the clarity and strength of the confident generalizations of primary prevention proponents such as Dr. Albee (We have a lot of evidence on the effectiveness of primary prevention ... it is available in the literature for all to read) and primary prevention critics such as Dr. Lamb (... The major functional mental illnesses, as well as the frequently occurring diagnosable minor illnesses, remain untouched by efforts to strengthen mental health.). However, it seems clear that the disagreement is not primarily a matter of differences in data interpretation (although this is clearly a part of the problem). Rather, it seems to be mostly a function of differences at the level of basic assumptions about the nature of mental illness and the appropriate scope of activity for mental health professionals.     

Media reviews

Of the three films reviewed in this issue, only the first, All Women Have Periods, deals with both areas of sexuality and disability. The second film, A Masturbatory Story, deals with sexuality but not disability. The third film, A Different Approach, deals with disability but not sexuality. The reason I have included the last two films are that A Masturbatory Story is one of the best, most permission giving films I have seen on the subject of masturbation and A Different Approach while focusing on employment of the disabled, is one of the most entertaining and effective films I have seen dealing with attitudes.     

Validation of the English version of the KINDL<Superscript>®</Superscript> generic children’s health-related quality of life instrument for an Asian population – results from a pilot test

ObjectivesTo evaluate the psychometric properties of the KINDL questionnaire in an Asian population. Methods: Consecutive patients with diabetes mellitus (DM) and healthy subjects were recruited to complete the English KINDL questionnaire. The inclusion criteria for patients were age 8–16years, English-speaking, diagnosed with DM and absence of co-morbid conditions. Results:Thirty children with DM (mean age: 10.7±1.35years; 11M) and 39 healthy subjects (mean age: 10.6±1.23years, 17M) completed the child version whereas 31 adolescents with DM (mean age: 14.5±1.48years; 15M) and 32 healthy subjects (mean age: 14.3±0.87years, 16M) completed the adolescent version. Overall, children with DM reported better HRQoL than healthy children. Although this appeared counter-intuitive, several explanations are possible: (1) the development of resilience to the disease over time, (2) our subjects are well-managed, (3) response shift, (4) the provision of high quality medical care, (5) compared to normal children, diabetic subjects and their family pay greater attention to health issues. The reliability coefficients were (overall, scales): KINDL-Kid DM (0.79, 0.44–0.65), KINDL-Kid Healthy (0.71, 0.60–0.80), KINDL-Kiddo DM (0.77, 0.37–0.74) and KINDL-Kiddo Healthy (0.84, 0.21–0.79). Conclusions: The KINDL questionnaire appeared promising for use in Asian children. However, further validation in a sample more representative of the general population is required.     

Cardiovascular prevention in the community: the plurisectorial program of the canton of Tessin

Summary It describes the primary prevention of cardiovascular diseases carried out in Tessin (Italian-speaking Switzerland). Every single action is adressed to the entire population, activelyinvolving professional associations (doctors), pharmacists, nurses, shop-keepers, etc.) and making use in particular of the collaboration of the mass-media (daily press, radio, television). The described actions concern the struggle against the cardiovascular risk factors through the daily diffusion of tv advertisements, free measurement of arterial pressure, and the possibility of disposing in the majority of regional restaurants of a Health menu with a low content of saturated fats and cholesterol. In 1984 every citizen of Tessin has been reached by an average of 24 preventive messages.

Riassunto E' descritto il programma di prevenzione primaria contro le malattie cardiovascolari attuata nel Canton Ticino (Svizzera). Le singole azioni si rivolgono a tutta la popolazione, coinvolgendo attivamente associazioni professionali (medici, farmacisti, infermieri, esercenti, ecc.) e si avvalgono soprattutto della collaborazione dei mass-media (stampa quotidiana, radio, e televisione). Le azioni descritte concernono la lotta ai fattori di rischio cardiovascolari tramite la diffusione quotidiana di spots pubblicitari televisivi, la misurazione gratuita della pressione arteriosa e la possibilità di disporre nel più gran numero di ristoranti del Cantone di un Piatto della Salute con un basso contenuto di grassi saturi e di colesterolo. Ogni abitante del Cantone é stato in media raggiunto nel corso del 1984 da 24 messaggi preventivi.

     

Comparison of attitudes toward transsexuality and homosexuality

Attitudes toward transsexuality and homosexuality were compared in a sample of 318 university students. More people felt that homosexuality was wrong than felt that transsexuality was wrong. This difference in favor of transsexuality was more pronounced in female than in male respondents. In addition, more people rejected the notion that biological factors were responsible for homosexuality than was the case for transsexuality. General attitudes about the morality of transsexuality and homosexuality, however, were not mirrored in response to questions pertaining to job discrimination. To the contrary, male respondents, especially, were more inclined toward equal opportunity for homosexuals than for transsexuals. One hypothesis supported by this study was that homosexual denial and homophobia in some transsexuals may, in part, be a reflection of society's greater moral condemnation of homosexuality relative to transsexuality.     

“Primary” Rationing of Health Services in Ageing Societies—A Normative Analysis

While most of the debate on rationing in health care focusses on the distribution of scarce medical resources among competing needs, which we propose to call secondary rationing, this paper is concerned with primary rationing, i.e., the conscious decision by society to limit the amount of resources devoted to a collectively financed health care system. Based upon a number of transparent normative criteria, we analyze whether primary rationing should be performed and, if so, what type should be chosen (hard vs. soft, explicit vs. implicit). Finally we discuss whether age should be used as a criterion in any systematic attempt at primary rationing of health care.     

The evaluation of pornography: Effects of attitude and perceived physiological reaction

Twenty-three medical and 28 nonmedical male student Ss read four erotic prose passages and then rated each on obscenity, censorship, and four semantic differential evaluation scales. Ss were given varying levels of false (experimenter-controlled) GSR feedback for each stimulus passage, as well as different explanations of the significance of this arousal feedback. Four-way analyses of variance showed that low Stolerance of erotica, pedophelic passage content, and GSR feedback indicating physiological arousal resulted in passages being labeled as more obscene and unfavorable. Explanations to Ss that GSR feed-back indicated sexual arousal resulted in more favorable ratings by the medical Ss and interacted with passage type for the nonmedical Ss. Concurrently monitored heart rate was not significantly influenced by any of the experimental variables and was (with one marginal exception) uncorrelated with any of the dependent labeling variables. An earlier version of this article was presented at the XVIIth International Congress of Applied Psychology, Liege, Belgium, July 1971.     

“Let's Talk About Sex, Baby”: Community-Based HIV Prevention Work and the Problem of Sex

Talking about sex and sexuality has been integral to HIV/AIDS prevention work in the United States since the beginning of the epidemic. Early prevention workers, who were primarily gay men, developed a sex-positive approach to prevention, involving frank discussions of sex and sexuality, with the idea of helping to end the epidemic by protecting oneself and one's sex partners from the disease. This article examines early prevention work at AIDS Action Committee (ACC) in Boston, Massachusetts, and details subsequent challenges to this approach, primarily from Bostonians outside of the gay community, but also from within AAC. The article ends with an examination of the early 2000s at AAC, which saw the more recent manifestation of a sex-positive approach to prevention in their work with HIV-infected individuals.     

Internal exposure to organic substances in a municipal waste incinerator

Summary Fifty-three persons occupied in a municipal waste incinerator were examined with respect to their internal exposure to organic substances which may be produced during pyrolysis of organic matter. For this purpose the levels of benzene in blood, polychlorinated biphenyls (PCBs) and hexachlorobenzene (HCB) in plasma, and mono- (MCPs), di- (DCPs), tri- (TCPs), tetra-(TECPs) and pentachlorophenol (PCP) and hydroxypyrene in urine were determined. For control purposes, 431 men and women were examined. Significantly higher values for the workers were found for the excretion of hydroxypyrene [median (m): 0.24vs 0.11 g/l; non-smokers], 2,4/2,5-DCP (m: 10.5 vs 3.9 g/l) and 2,4,5-TCP (m: 1.2 vs 0.8 g/l) and for the HCB level in plasma (m: 4.4 vs 2.8 g/l). For the concentrations of 4-MCP and 2,3,4,6/2,3,5,6-TECP, the controls had significantly higher concentrations in urine than did the workers in the incineration plant (m: 4-MCP 1.7 vs 1.2; 2,3,4,6/2,3,5,6-TECP: 1.2 vs 0.3 g/l). No significant differences between workers and controls were detected with respect to benzene in blood (m: 0.20 vs 0.28 g/l; non-smokers), 2,4,6-TCP and PCPs in urine (m: 0.85 vs 0.60 and 2.2 vs 2.2 g/l) or the levels of PCB congeners in plasma (m: 138, 153, 180: 5.6 vs 4.1 g/l). The elevated levels of hydroxypyrene, 2,4/2,5-DCP, 2,4,5-TCP and HCB in biological material may be related to the incineration of the waste. These elevations, however, are very small and are of interest more from the environmental than from the occupational point of view.     

Toxicity of aldicarb and fonofos to the early-life-stage of the fathead minnow

Flow-through early-life-stage (ELS) toxicity tests were conducted with the pesticides aldicarb (Temik^®) and fonofos (Dyfonate^®) to determine their effect on the survival and growth of fathead minnows. Concentrations of 78g/L of aldicarb and 16g/L of fonofos did not affect survival and growth. However, 156g/L of aldicarb and 33g/L of fonofos were lethal to larval-juvenile exposed for 30 days post-hatch. The maximum acceptable toxicant concentration (MATC) of aldicarb and fonofos for the fathead minnow is estimated to be between 78–156g/L and 16–33g/L, respectively. The corresponding chronic values (geometric mean of MATC values) would be 110g/L and 23g/L. Acute toxicity tests gave 96-hr LC50 values of 1370g aldicarb/L and 1090g fonofos/L. The acute-chronic ratio (96-hr LC50/chronic value) is 12 for aldicarb and 47 for fonofos.     

The determinants of CABG patients' outcomes

This study examined the selfreported health status of 90 patients who had undergone Coronary Artery Bypass Grafting (CABG). Data were collected by the Short Form36 (SF36) instrument, administered twice at preoperative and postoperative periods. The reliability of the SF36 ranged from 0.68 to 0.93 in the analysis of preoperative and postoperative measures of health status. The CABG patients reported markedly lower health status on all eight SF36 dimensions at the preoperative period and considerable improvements on all dimensions at the postoperative period. The assessment of CABG patients' outcomes showed that perceived usefulness of the procedure contributed positively to their perceived health status when the effect of preoperative health status was controlled. Patients who perceived the CABG procedure as useful appeared to have more improved postoperative health status after the procedure.     

Isomer-specific analysis and toxic evaluation of polychlorinated biphenyls in striped dolphins affected by an epizootic in the western Mediterranean sea

Isomer-specific concentrations of polychlorinated biphenyls (PCBs) including planar, mono- and di-ortho congeners and concentrations of DDT were determined in striped dolphins affected by a morbillivirus epizootic in the western Mediterranean in 1990. Extremely high concentrations of PCBs ranging from 94 to 670 g/g (wet wt) were detected in the blubber. Similarly, DDT concentrations were high, between 22 and 230 g/g (wet wt). The concentrations of three non-ortho coplanar PCBs were 43 (3,3,4,4-T₄CB), 6.8 (3,3,4,4,5-P₅CB), and 7.8 (3,3,4,4,5,5-H₆CB) ng/g (wet wt), respectively, the highest residue levels reported to date. The estimated 2,3,7,8-TCDD toxic equivalents of non-, mono- and di-ortho PCB congeners in striped dolphins were several times higher than those observed for other marine mammals and humans. Mono-ortho congeners contributed greater 2,3,7,8-TCDD toxic equivalents than non-ortho members. The higher ratio of 3,3,4,4,5,5-H₆CB/3,3,4,4,5-P₅CB (IUPAC 169/126) suggested a strong induction of mixed function oxidase enzymes and highlighted the possibility of using this ratio as an index for risk assessment of PCB contamination in marine mammals. Elevated concentrations of PCBs may have played a role in the immune depression in striped dolphins, ultimately leading to the development of morbillivirus disease.     

Polychlorobiphenyls, ΣDDT,and hexachlorocyclohexane isomers in the western North Pacific ecosystem

Polychlorobiphenyls (PCBs), DDT (p,p-DDT,p,p-DDD, andp,p-DDE and HCH isomers (hexachlorocyclohexanes including , , and isomers) were determined in a marine food chain, including seawater, zooplankton, myctophid, squid and striped dolphin collected from the western North Pacific waters. The concentrations of these pollutants increased in higher trophic levels, where the highest bioconcentration factors (concentration ratio in organisms to water), as much as 10⁷, were obtained from both PCBs and DDT in striped dolphin. The proportions of highly chlorinated biphenyls,p,p-DDE and -HCH increased in higher-ranking predators. These observations suggest that the bioaccumulation mechanisms in lower trophic levels depend primarily on the physicochemical properties of pollutants, whereas those in higher trophic levels are affected by the biodegradability of the pollutants and the metabolic capacity and life-span of the organisms.     

Blood styrene concentrations in a “normal” population and in exposed workers 16 hours after the end of the workshift

Summary Blood styrene was measured by a gas chromatography-mass spectrometry method in 81 normal people and in 76 workers exposed to styrene. In the normal subjects, styrene was also tested in alveolar and environmental air. Styrene was found in nearly all (95%) blood samples. Average styrene levels in the normal subjects were 221 ng/1 in blood (Cb), 3 ng/1 in alveolar air (Ca) and 6 ng/1 in environmental air (Ci). Styrene levels did not differ significantly between smokers and non-smokers, 95% of values being below 512 ng/1 in Cb, 7 ng/1 in Ca and 15 ng/l in Ci. In workers with an average exposure to styrene of 204 g/l, at the end of the workshift, mean blood styrene concentration was 1211 g/l. In blood samples collected at the end of the Thursday shift, styrene levels were significantly higher (1590 g/1) than those found at the end of the Monday shift (1068 g/l. A similar difference was found in samples taken the morning after exposure (60 and 119 g/l, respectively). Significant correlations between blood and environmental styrene were found both at the end of the shift and the morning after exposure (r=0.61 and 0.41, respectively). In workers occupationally exposed to styrene, 16 h after the end of the workshift, blood styrene (94 g/l) was significantly higher than that found in the normal subjects (0.22 g/l). The half-life of blood styrene was 3.9 h.     

Effects of tributyltin on survival,growth, morphometry,and RNA-DNA ratio of larval striped bass,Morone saxatilis

Effects of tributyltin (TBT) on survival, growth, morphometry, and RNA-DNA ratio in larval striped bass(Morone saxatilis) were assessed in three experiments. In Experiment I, 13 day old larvae were exposed to 0, 0.067, 0.766, or 2.284 g TBT/L for 6 days. All larvae exposed to 2.284 /L died by day 5; exposure to 0.766 g/L significantly reduced survival relative to controls (59.8% vs. 81.8%). Significant, concentration-dependent decreases in body depth occurred in larvae exposed to 0.067 and 0.766 g/L. In Experiment II, all 16 day old larvae exposed to 1.498 g/L died by day 6. Survival, weight, and morphometry parameters were not significantly different in larvae exposed to 0, 0.052, or 0.444 g/L for 7 days. In Experiment III, survival was similar in 21 day old larvae exposed to 0, 0.055, 0.218, or 0.514 /L for 7 days. Notochord length and dry weight decreased significantly in larvae exposed to 0.514 g/L. Weight and morphometry parameters were more sensitive indicators of sublethal stress than RNA-DNA ratio. Maximum TBT concentrations reported in Chesapeake Bay marinas are likely to cause increased larval mortality. Longer-term studies are needed to assess effects at <0.050 g/L, which may be more representative of habitat conditions.
