Trends in food availability in Portugal in 1966–2003

BACKGROUND: Dietary intake has changed considerably in South European countries, but whether those changes were similar between countries is currently unknown. AIM OF THE STUDY: To assess the trends in food availability in Portugal and four other Mediterranean countries from 1966 to 2003. METHODS: Food and Agricultural Organization food balance sheets from Portugal, France, Italy, Greece and Spain. Trends were assessed by linear regression. RESULTS: The per capita availability of calories has increased in Portugal, France, Greece, Italy and Spain in the past 40 years. Portugal presented the most rapid growth with an annual increase of 28.5 +/- 2.2 kcal (slope +/- standard error), or +1000 kcal overall. In animal products, Portugal had an annual increase of 20.7 +/- 0.9 kcal, much higher than the other four countries. Conversely, the availabilities of vegetable and fruit only showed a slight growth of 1.0 +/- 0.1 kcal/year and 2.5 +/- 0.4 kcal/year, respectively, thus increasing the ration of animal to vegetable products. Olive oil availability increased in all countries with the notable exception of Portugal, where a significant decrease was noted. Wine supply decreased in all five countries; in contrast, beer supply started to take up more alcohol share. Percentage of total calories from fat increased from nearly 25% to almost 35% in Portugal during the study period, mainly at the expenses of calories from carbohydrates, whereas the share of protein showed just a slight increase. Furthermore, fat and protein were increasingly provided by animal products. CONCLUSIONS: Portugal is gradually moving away from the traditional Mediterranean diet to a more Westernized diet as well as France, Greece, Italy and Spain. Noticeably, the trends of diet transition were observed relatively faster in Portugal than in the other four Mediterranean countries.     

Reproduction in the year 2012: in vivo or in vitro?

The Dutch Minister of Health has proposed reducing the number of reimbursed in vitro fertilisation (IVF) cycles per couple from 3 to 1, in order to save 30 million euros per year. In the Netherlands, the number of IVF cycles has increased by 50% in the past 13 years, resulting in, on average, one child conceived through IVF in every classroom today. The increase in the number of IVF treatments is also caused by expansion of the indications for IVF, despite the lack of evidence proving the effectiveness of IVF for some of these indications. In a time of financial constraint, the restriction of reimbursed indications would be fairer than reducing the number of reimbursed treatments with IVF or intracytoplasmic sperm injection (ICSI) for all couples.     

Ethnic differences in self reported health in Malmö in southern Sweden

STUDY OBJECTIVE—The aim of this study was to investigate ethnic differences in self reported health in the city of Malmö, Sweden, and whether these differences could be explained by psychosocial and economic conditions.
DESIGN/SETTING/PARTICIPANTS—The public health survey in Malmö 1994 was a cross sectional study. A total of 5600 people aged 20-80 years completed a postal questionnaire. The participation rate was 71%. The population was categorised according to country of origin: born in Sweden, other Western countries, Yugoslavia, Poland, Arabic speaking countries and all other countries. The multivariate analysis was performed using a logistic regression model in order to investigate the importance of possible confounders on the differences by country of origin in self reported health. Finally, variables measuring psychosocial and economic conditions were introduced into the model.
MAIN RESULTS—The odds ratios of having poor self reported health were significantly higher among men born in other Western countries, Yugoslavia, Arabic speaking countries and in the category all other countries, as well as among women born in Yugoslavia, Poland and all other countries, compared with men and women born in Sweden. The multivariate analysis including age and education did not change these results. A huge reduction of the odds ratios was observed for men and women born in Yugoslavia, Arabic speaking countries and all other countries, and for women born in Poland after the introduction of the social network, social support and economic factors into the multivariate model.
CONCLUSIONS—There were significant ethnic group differences in self reported health. These differences were greatly reduced by psychosocial and economic factors, which suggest that these factors may be important determinants of self rated health in certain minority groups.


     

Regional variations in pedal cyclist injuries in New Zealand: safety in numbers or risk in scarcity?

Objective: To assess regional variations in rates of traffic injuries to pedal cyclists resulting in death or hospital inpatient treatment, in relation to time spent cycling and time spent travelling in a car. Methods: Cycling injuries were identified from the Mortality Collection and the National Minimum Dataset. Time spent cycling and time spent travelling as a driver or passenger in a car/van/ute/SUV were computed from National Household Travel Surveys. There are 16 census regions in New Zealand, some of which were combined for this analysis to ensure an adequate sample size, resulting in eight regional groups. Analyses were undertaken for 1996–99 and 2003–07. Results: Injury rates, per million hours spent cycling, varied widely across regions (11 to 33 injuries during 1996–99 and 12 to 78 injuries during 2003–07). The injury rate increased with decreasing per capita time spent cycling. The rate also increased with increasing per capita time spent travelling in a car. There was an inverse association between the injury rate and the ratio of time spent cycling to time spent travelling in a car. The expected number of cycling injuries increased with increasing total time spent cycling but at a decreasing rate particularly after adjusting for total time spent travelling in a car. Conclusions: The findings indicate a ‘risk in scarcity’ effect for New Zealand cyclists such that risk profiles of cyclists are likely to deteriorate if fewer people use a bicycle and more use a car. Implications: Cooperative efforts to promote cycling and its safety and to restrict car use may reverse the risk in scarcity effect.     

Whooping cough surveillance in France in pediatric private practice in 2006–2015

BackgroundIncreasing incidence of whooping cough (pertussis) has been reported in many countries, attributed to a switch from whole-cell pertussis-containing vaccine (wPV) to acellular PV (aPV) and circulation of the pertactin non-producing Bordetella pertussis. The present study aimed to estimate the duration of immunity conferred by PVs in children in France with data from an ongoing pediatric ambulatory surveillance of pertussis.MethodsA total of 64 pediatricians throughout France enrolled children with suspected pertussis. A standardized data form was used to collect data on age sex, vaccination status, brand of wPV or aPV and source of infection. Confirmed cases were positive on culture and/or real-time Polymerase Chain Reaction (for B.-non-classified or B. pertussis or B. parapertussis) and/or pertussis serology.ResultsBetween October 2006 and December 2015, 149 cases of confirmed Bordetella infections were reported, 86 infected with B. pertussis and 55 B. non-classified. Fifteen children (10.1%) were not vaccinated, and 26 (17.4%) were partially vaccinated. The mean age was greater for children who received 4 doses of wPV (11.3 ± 2.2, p < 0.001) or a combination of wPV and aPV (10.5 ± 3.3, p < 0.001) than only aPV (7.2 ± 2.4 years). The mean duration of cough before a visit to a pediatrician was longer for children with wPV or a combination of wPV and aPV than only aPV (23.8 ± 10.1 and 25.0 ± 25.6 vs 13.6 ± 10.0 days).ConclusionDespite the use of a more sensitive diagnostic method and emergence of pertactin non producing B. pertussis, in France context, aPV-induced immunity still protects against pertussis; however, the mean duration of immunity is about 6 to 7 years, compared to 9 years for wPV vaccine, after the primary vaccination and one booster (3 + 1 doses).     

Does the Heartbeat Award scheme in England result in change in dietary behaviour in the workplace?

The Heartbeat Award (HBA) scheme is a national nutrition labelling scheme that operates throughout England. The aim of this study was to assess whether the implementation of the HBA scheme in the workplace results in an improvement in eating habits at work. A longitudinal survey of employees using a structured questionnaire pre- and post-HBA intervention in six workplaces in Leicestershire, England, was conducted. A qualitative food frequency questionnaire was used to assess dietary behaviour 6 months before the scheme was implemented and 6 months afterwards. Four HBA workplaces (n = 453 employees) were compared with two comparison workplaces (n = 124 employees). The outcome measures for dietary change were consumption of 20 food items, i.e. 16 food-frequency and four food-type items. Changes in pre-intervention data compared with post-intervention data evaluated the impact of the HBA on eating habits. Differences were considered statistically different at the p < 0.05 level. Crude and adjusted odds ratios were used to assess differences in change in dietary behaviour between the intervention and comparison workplaces. The results showed that there was significantly more positive change in intervention workplaces only (i.e. the changes were not detected in the comparison workplaces) for four of the 20 food items tested: increase in consumption of fruit (p = 0.029); reduction in consumption of fried foods (p = 0.044) and sweet puddings (p = 0.042); and change to lower fat milks (p = 0.034). In conclusion, the HBA had a modest impact on dietary intake, resulting in a significant positive change in four out of 20 foods consumed by employees in HBA-holding premises.

Pesticides in Fresh Potatoes Sold in Farmers’ Markets in Alberta,Canada

Fresh potatoes (228 samples) from 34 farmers’ markets in Alberta were analyzed for 29 pesticides. Residues of three different pesticides were found in the samples tested with chlorpropham being most frequently detected (n = 13) at concentrations ranging from 15 to 7,600 μg kg⁻¹. Azoxystrobin (n = 11) and imidacloprid (n = 8) were found at concentrations ranging from 0.6 to 5.1 and 15–31 μg kg⁻¹, respectively. All pesticide concentrations were below Canadian maximum residue limits as established for potatoes. No pesticide residues were detected in 23 potato samples obtained from certified organic farmers.     

Ethnic variations in mortality in pre-school children in Denmark, 1973–2004

The objective of the study was to describe ethnic differences in under-five-years mortality in Denmark according to maternal country of origin. We conducted a large registry-linkage study of all singleton live-born children from mothers born in Denmark and from the ten largest migrant groups (n = 1,841,450). Study outcomes were death before the age of 5 years from all causes combined and the most frequent death causes. Results showed that children of mothers of Turkish, Pakistani, Somali and Iraqi origin had an elevated risk of dying before the age of five compared to offspring of mothers born in Denmark, with hazards ratios and 95% confidence intervals of 1.48 (1.31–1.67), 1.97 (1.68–2.32), 1.70 (1.29–2.25), and 1.92 (1.41–2.62), respectively. Ethnic differences were also observed in the underlying causes of death. Children of mothers born in Former Yugoslavia, Lebanon, Norway, Sweden, Iran, and Afghanistan did not differ in under-five-years mortality from ethnic Danish children. Adjustments for household income did not attenuate the risk estimates. In conclusion, we found excess child mortality in some migrant groups, but not in all. The differences could not be explained by socioeconomic status.     

Trends in income-related health inequalities in self-assessed health in Korea, 1998–2011

This study assesses income-related health inequalities in self-assessed health (SAH) and its trend from 1998 to 2011 in Korea that covers important time periods of financial crisis and post-crisis. Data came from the Korean National Health and Nutrition Examination Survey from 1998 to 2011. A population-representative sample aged 46 years and older was analysed. SAH was used as an indicator of health status, with household equivalence income as a proxy for socio-economic position. Age-adjusted prevalence rates of SAH were analysed to estimate both absolute and relative measures of health inequalities and the trend over time by the relative index of inequality (RII) and the slope index of inequality (SII). Results indicated that the highest level of health inequalities was found among men aged 46–59 years, especially in 2001 and 2005. For men, there was no clear, consistent pattern of increase or decrease in the trend over time. On the other hand, increasing trends in the RII and SII were found for women, except for women aged 46–59 years who reported a decreasing trend in the SII. Trends in health inequalities over time were influenced by economic crisis, demonstrating the need for macro-level economic policies as well as health policies addressing health gaps.     

Is Economic Inequality in Infant Mortality Higher in Urban Than in Rural India?

This paper examines the trends in economic inequality in infant mortality across urban–rural residence in India over last 14 years. We analysed data from the three successive rounds of the National Family Health Survey conducted in India during 1992–1993, 1998–1999, and 2005–2006. Asset-based household wealth index was used as the economic indicator for the study. Concentration index and pooled logistic regression analysis were applied to measure the extent of economic inequality in infant mortality in urban and rural India. Infant mortality rate differs considerably by urban–rural residence: infant mortality in rural India being substantially higher than that in urban India. The findings suggest that economic inequalities are higher in urban than in rural India in each of the three survey rounds. Pooled logistic regression results suggest that, in urban areas, infant mortality has declined by 22 % in poorest and 43 % in richest. In comparison, the decline is 29 and 32 % respectively in rural India. Economic inequality in infant mortality has widened more in urban than in rural India in the last two decades.     

The dioxin in chicken incident in Belgium in 1999: trouble or trifle?

Early 1999 dioxin-contaminated feedstuff was responsible for a poisoning at Belgian poultry farms resulting in seriously affected animals and products. Scarce data indicated levels of 500-1000 pg TEQ/g chicken fat, whereas 2-3 pg is normal. Consumption chicken weigh 1-1.5 kg and the average fat level is 15-20%. National Institute of Public Health and the Environment (RIVM), Bilthoven, the Netherlands evaluated the health risks with respect to long-term average consumption and incidental high consumption. The average annual consumption of chicken fat amounts to 1 g/day, resulting in an intake of 7-14 pg TEQ/kg bw/day, while incidental consumption of one half chicken led to an intake of 45-70 g fat, corresponding to 320-1000 pg TEQ/kg bw. The consumption exceeded the tolerable daily intake for dioxins (1-4 pg TEQ/kg bw/day) 2- to 14-fold and 80- to 1000-fold, respectively. Considering all available data RIVM concluded that negative health effects following long-term average consumption or incidental high consumption of contaminated chicken were unlikely to occur, but could not fully exclude minor subclinical effects.     

Geographical variation in disease progression in HIV-1 seroconverted injecting drug users in Europe?

BACKGROUND: Human immunodeficiency virus (HIV) disease progression might vary by geographical region due to differences in the spectrum of HIV-related illnesses and (access to) health care. Therefore, the effect of geographical region, next to the effect of other potential cofactors, on disease progression in 664 injecting drug users (IDU) with documented HIV seroconversion from eight cohorts in Europe was studied. METHODS: Kaplan-Meier methods and Cox proportional hazards analysis were performed to assess the effect of geographical region, other sociodemographics, drug use and repeated HIV exposure on progression from HIV seroconversion to immunosuppression, AIDS and death with AIDS. We considered the confounding effect of study-design related factors (e.g. setting of follow-up), and accounted for pre-AIDS death from natural causes by imputing when each endpoint would have occurred, had they not died without AIDS. RESULTS: Estimates of progression to AIDS and death with AIDS were substantially faster after taking pre-AIDS mortality into account. Median incubation time from seroconversion to the first CD4 count < 200 cells/microliter was 7.7 years (95% CI: 7.1-8.3) and to AIDS 10.4 years (95% CI: 9.8-infinity). The 10-year survival was 70.3% (95% CI: 62.8-76.6). The relative hazards (RH) of AIDS for IDU from central and southern Europe compared with IDU from northern Europe was 1.9 (95% CI: 1.2-3.0) and 1.2 (95% CI: 0.6-2.3), respectively, before, and 1.5 (95% CI: 0.7-3.2) and 1.1 (95% CI: 0.6-2.3) after taking differences in study-design related factors into account. Accounting for these factors, the RH of death with AIDS was 0.9 (95% CI: 0.3-2.5) for central and 1.2 (95% CI: 0.4-3.4) for southern Europe compared with northern Europe. For the first CD4 count < 200 cells/microliter these figures were 0.8 (95% CI: 0.5-1.4) and 0.8 (95% CI: 0.5-1.4). Age at seroconversion was the strongest predictor of disease progression. No statistically significant differences in disease progression were found by gender, foreign nationality, drug use and potential repeated HIV exposure. CONCLUSIONS: We found no evidence for regional variability in HIV disease progression among European IDU. Future studies evaluating geographical differences should consider the confounding effect of study-design related factors and differential non-AIDS mortality. As age is an important determinant of disease progression, it should be considered in recommending treatment.     

Comparison of in vivo and in vitro tests of resistance in patients treated with chloroquine in Yaoundé, Cameroon

The usefulness of an isotopic in vitro assay in the field was evaluated by comparing its results with the therapeutic response determined by the simplified WHO in vivo test in symptomatic Cameroonian patients treated with chloroquine. Of the 117 enrolled patients, 102 (87%) completed the 14-day follow-up, and 95 isolates obtained from these patients (46 children, 49 adults) yielded an interpretable in vitro test. A total of 57 of 95 patients (60%; 28 children and 29 adults) had an adequate clinical response with negative smears (n = 46) or with an asymptomatic parasitaemia (n = 11) on day 7 and/or day 14. The geometric mean 50% inhibitory concentration of the isolates obtained from these patients was 63.3 nmol/l. Late and early treatment failure was observed in 29 (30.5%) and 9 (9.5%) patients, respectively. The geometric mean 50% inhibitory concentrations of the corresponding isolates were 173 nmol/l and 302 nmol/l. Among the patients responding with late and early treatment failure, five isolates and one isolate, respectively, yielded a discordant result (in vivo resistance and in vitro sensitivity). The sensitivity, specificity, and predictive value of the in vitro test to detect chloroquine-sensitive cases was 67%, 84% and 86%, respectively. There was moderate concordance between the in vitro and in vivo tests (kappa value = 0.48). The in vitro assay agrees relatively well with the therapeutic response and excludes several host factors that influence the results of the in vivo test. However, in view of some discordant results, the in vitro test cannot substitute for in vivo data on therapeutic efficacy. The only reliable definition of "resistance" in malaria parasites is based on clinical and parasitological response in symptomatic patients, and the in vivo test provides the standard method to determine drug sensitivity or resistance as well as to guide national drug policies.
