Unhas humanas como marcadores biológicos de exposição ao flúor: correlação com a saliva da parótida e influência da idade / Human nails as biological markers of fluoride exposure: correlation to parotid ductal saliva and influence of ageFukushima, Rejane 07 December 2007 (has links)
Avaliou-se a influência da exposição ao flúor (F) através da água de beber, da velocidade de crescimento das unhas, da idade e do gênero na concentração deste elemento nas unhas das mãos e dos pés. Em adição, verificou-se a correlação entre as concentrações de F na saliva total, saliva do ducto da parótida e unhas das mãos e dos pés. Participaram do estudo 300 indivíduos, das faixas etárias de 3-7,14-20, 30-40 e 50-60 anos, residentes de cinco comunidades brasileiras, sendo duas no Estado de São Paulo (Pirajuí e Bauru, com água não fluoretada e 0,7 mgF/L na água de abastecimento, respectivamente) e três no Estado da Paraíba (Cajazeirinhas, Brejo dos Santos e Brejo das Freiras, com 0,2, 0,7 e 1,7 mgF/L na água de consumo, respectivamente). Foram coletadas duas ou três (apenas em Bauru) amostras de água de beber, além de duas amostras de: unhas dos pés, unhas das mãos, saliva total e saliva do ducto da parótida de cada indivíduo. O F nas amostras foi analisado com eletrodo íon-específico. Os dados obtidos foram analisados estatisticamente através de análise de variância e regressão linear (p<0,05). A exposição ao F através da água de beber, a velocidade de crescimento das unhas, a idade e o gênero influenciaram a concentração de F nas unhas das mãos e dos pés, sendo que o fator de exposição ao F através da água foi o que exerceu maior influência pelo modelo de regressão linear adotado. As unhas dos pés (R2=0,46) se mostraram melhores indicadoras de exposição ao F do que as das mãos (R2=0,24). Foi encontrada uma correlação negativa significativa entre velocidade de crescimento das unhas e concentração de F nas mesmas. Houve correlação positiva significativa entre concentração de F nas unhas das mãos e dos pés com: saliva total (r=0,36 e r=0,41) e saliva do ducto da parótida (r=0,25 e r=0,53), respectivamente. Também se observou correlação positiva entre saliva total e do ducto da parótida (r=0,24), bem como entre concentração de F na água e saliva total (r=0,41) e saliva do ducto (r=0,65). Todos os fatores testados influenciaram os níveis de F nas unhas e, portanto, devem ser levados em consideração quando se utiliza este marcador biológico. / The influence of fluoride (F) concentration in the drinking water, nails growth rate, age and gender upon the F content in fingernail and toenail were evaluated. In addition, the correlations among the F concentrations in whole saliva, parotid ductal saliva and finger/toenails were verified. Three hundred volunteers of 3-7, 14-20, 30-40, 50-60 years participated. They were residents of five Brazilian communities, two in Sao Paulo State (Pirajuí and Bauru, non-fluoridated and 0.7 mgF/L artificially fluoridated drinking water, respectively) and three in Paraiba State (Cajazeirinhas, Brejo dos Santos and Brejo das Freiras, 0.2, 0.7 and 1.73 mgF/L naturally fluoridated drinking water, respectively). Two or three samples of drinking water, and two samples of fingernails, toenails, whole saliva and ductal saliva were collected from each volunteer, with one-week interval period between the collections. F in water, whole saliva, ductal saliva and nails was determined using the ion-sensitive electrode. Data were analyzed by ANOVA and linear regression (p<0.05). The F exposure from the drinking water, nails growth rate, age and gender influenced the levels of F in fingernails and toenails. Considering the model of multivariate linear regression adopted, F exposure from the water influenced the most. Toenails (R2=0.46) seemed to be better indicators of F than fingernails (R2=0.24). It was found a significant negative correlation between nails growth rate and their content of F. Positive correlations were found between F concentration in fingernails and toenails and: F concentration in whole saliva (r=0.36 and r=0.41) and in parotid ductal saliva (r=0.25 and r=0.53), respectively. Moreover, it was observed a positive correlation between whole and parotid saliva (r=0.24), as well as between F concentration in the drinking water and whole (r=0.41) and parotid saliva (r=0.65). All factors that influenced nails F concentration must be taken into account when using them as biological markers.

Socioeconomic status and health: exploring biological pathwaysLucas, Robyn Marjorie, robyn.lucas@anu.edu.au January 2004 (has links)
The cross-sectional Biomarkers Study was undertaken in Canberra, Australia (2000-2002) to examine the role of psychosocial factors in the socioeconomic health gradient, via physiological changes consequent upon activation of the neuroendocrine
stress response.¶
The study population was derived from healthy 40-44 year old men and women
already participating in a longitudinal cohort study. Using data from the cohort study, four groups with similar occupational status were formed. The study sample was randomly selected within these groups, thus representing the socioeconomic spectrum.¶
A pilot study involved 60 participants with blood and saliva samples measured on two occasions. A further 302 people had blood and saliva samples taken on one occasion. Socioeconomic status was measured by occupational code and status,
personal and household income, education and perceived position in the community and in Australia. Psychosocial and behavioural factors, including job strain, job security, coping style, anxiety, depression, optimism, self-esteem, sense of belonging and trust, social support, smoking, exercise and alcohol intake were assessed by selfreport.
Five biological parameters: plasma fibrinogen, glycated haemoglobin, waisthip ratio, serum neopterin and salivary IgA were measured as outcome variables.Three hypotheses were tested:¶
1. There is a socioeconomic gradient in measures of psychosocial stress, and of
psychological resilience.¶
2. There is a socioeconomic gradient in biological measures that have a plausible¶
association with future disease.
3. Psychosocial factors mediate the demonstrated association between
socioeconomic status and the biological measures.¶
Data analysis confirmed a socioeconomic gradient in some psychosocial and
behavioural variables: economic strain (r=-0.44, p<0.001), job demands (r=0.45,
p<0.001), job control (r=0.26, p<0.001), active coping style (r=0.28, p <0.001), sense
of optimism (r=0.24, p<0.001), social capital (r=0.26, p<0.001), job security (r=0.17,
p=0.002), job marketability (r=-0.16, p=0.005), sense of belonging (r=0.22, p<0.001),
number of adverse life events (r=-0.13, p=0.01) and positive interaction with family
and friends (r=0.20, p<0.001 ), vigorous physical activity (r=-0.16, p=0.002), alcohol
consumption (r=0.30, p<0.001) and smoking status (r=-0.25, p<0.001). There was no
socioeconomic gradient in anxiety, depression, neuroticism, hostility, locus of
control, self-esteem, perceived stress or mental health (SF-12). Four of the five
biological markers varied with socioeconomic status: plasma fibrinogen (female (F):
r=-0.26, p=0.002, male (M) r=-0.08, p=0.30), glycated haemoglobin (F: r=-0.23,
p=0.01, M: r=-0.11, p=0.17), waist-hip ratio (F: r=-0.19, p=0.03, M: r=-0.27,
p<0.001), serum neopterin (F: r=-0.21, p=0.009, M: r=-0.04, p=0.56), salivary IgA
(F: r=-0.07, p=0.38, M: r=0.004, p=0.97). A more adverse biological profile was
associated with lower socioeconomic status. Work characteristics, coping style,
smoking and exercise were particularly important mediators of the association
between the biological markers and socioeconomic status. Particular psychosocial factors were consistent mediators of the association between specific biomarkers and
socioeconomic status (with little variation for different measures of socioeconomic
status). However, the particular psychosocial factors providing significant mediation
varied for the different markers.¶
In this sample of healthy 40-44 year olds, four out of five biological markers showed
moderate socioeconomic variation with a more favourable profile associated with
higher SES. The data provide limited support for the importance of psychosocial
factors in the socioeconomic health gradient.
