Eating Macro-Algae (Seaweed): Understanding Factors Driving New Zealand Consumers' Willingness to Eat and Their Perceived Trust towards Country of Origin

Macro-algae is an umbrella term for seaweed, which is an important ingredient in many novel food products in New Zealand and other Australasian countries. While attitudes, consumption motivation, knowledge, and socio-demographic consumer profiles have been investigated in specific countries in the region, consumer behavior such as willingness to eat and factors driving this behavior have not yet been explored. Therefore, the present study fills this research gap in a New Zealand context and explores predictors of New Zealand consumers' willingness to eat macro-algae and their perceived trust towards the countries of origin of these products. The symbolic value of food, health importance, food safety concerns, and food fussiness were the factors under investigation. The work builds on an online questionnaire and a sample of 437 consumers mirroring the New Zealand population in terms of gender, age, and annual household income. Data were collected through an opt-in panel provider in November 2023. The data analysis consisted of descriptive statistics and partial least square structural equation modeling. Results show that health importance and food fussiness tendencies are the strongest predictors of willingness to eat and trustworthiness of the two countries of origin. Best practice recommendations for marketing managers in New Zealand food retail are provided.

Incidence of atrial fibrillation and flutter in Denmark in relation to country of origin: a nationwide register-based study

BACKGROUND

Atrial fibrillation and flutter (AF) is the most common sustained arrhythmia with an increasing prevalence in Western countries. However, little is known about AF among immigrants compared to non-immigrants.

AIM

To examine the incidence of hospital-diagnosed AF according to country of origin.

METHOD

Immigrants were defined as individuals born outside Denmark by parents born outside Denmark. AF was defined as first-time diagnosis of AF. All individuals were followed from the age of 45 years from 1998 to 2017. The analyses were adjusted for sex, age, comorbidity, contact with the general practitioner and socioeconomic variables. Adjustment was conducted using standardised morbidity ratio weights, standardised to the Danish population in a marginal structural model.

RESULTS

The study population consisted of 3,489,730 Danish individuals free of AF and 108,914 immigrants free of AF who had emigrated from the 10 most represented countries. A total of 323,005 individuals of Danish origin had an incident hospital diagnosis of AF, among the immigrants 7,300 developed AF. Adjusted hazard rate ratios (HRRs) of AF for immigrants from Iran (0.48 [95%CI:0.35;0.64]), Turkey (0.74 [95%CI:0.67;0.82]) and Bosnia-Herzegovina (0.42 [95%CI:0.22;0.79]) were low compared with Danish individuals. Immigrants from Sweden, Germany and Norway had an adjusted HRR of 1.13 [95%CI:1.03;1.23], 1.12 [95%CI:1.05;1.18] and 1.11 [95%CI:1.03;1.21], respectively (Danish individuals as reference).

CONCLUSIONS

Substantial variation in the incidence of hospital-diagnosed AF according to country of origin was observed. The results may reflect true biological differences but could also reflect barriers to AF diagnosis for immigrants. Further efforts are warranted to determine the underlying mechanisms.

Adherence to a Traditional Mexican Diet Is Associated with Lower Hepatic Steatosis in US-Born Hispanics of Mexican Descent with Overweight or Obesity

Hispanics of Mexican descent have disproportionate rates of non-alcoholic fatty liver disease (NAFLD). The purpose of this work is to investigate the association between the traditional Mexican diet score (tMexS) and hepatic steatosis and fibrosis, two NAFLD-related clinical endpoints, in Hispanic adults of Mexican descent. Data from 280 Hispanic adults of Mexican descent (n = 102 men, 178 women) with overweight or obesity enrolled in a cross-sectional observational study were analyzed. The tMexS was calculated from 24 h dietary recalls. Hepatic steatosis and fibrosis measurements were assessed using transient elastography (Fibroscan®). Linear regression models testing the association between tMexS and hepatic steatosis and fibrosis were run individually and through the stratification of significant modifiers. Mean tMexS were 5.9 ± 2.1, hepatic steatosis scores were 288.9 ± 48.9 dB/m, and fibrosis scores were 5.6 ± 2.2 kPa. Among the US-born group, with every point increase in the tMexS, there was a statistically significant 5.7 lower hepatic steatosis point (95% CI: -10.9, -0.6, p-value = 0.07). Higher adherence to a traditional Mexican diet was associated with lower hepatic steatosis in US-born Hispanics of Mexican descent. Findings from the current work may serve to inform future culturally relevant interventions for NAFLD prevention and management in individuals of Mexican descent.

Importance of the origin, organic production and other extrinsic parameters in fruit and vegetable choices

The aims of the present work were to evaluate consumers' perceptions and purchasing habits in relation to fruit and vegetables and to determine the importance of the production type, price and geographical origin of such products for consumers' purchasing decisions. For this purpose, an online consumer survey was conducted to determine Spanish people's opinions and consumption habits in relation to fruit and vegetables, especially those from organic farming. The survey also included a part to assess the importance that consumers attach to different extrinsic attributes in oranges and avocado pears (with a conjoint analysis), and a section to determine the participants' ethnocentrism. Consumers agree that organic food respects the environment more, contains fewer 'chemicals' and is more natural. Price is the first reason why many people do not buy organic food, followed by them thinking that they do not offer any added value and they are difficult to find. For the Spanish population, country of origin, local production, seasonality and price are much more important attributes for purchasing fruit and vegetables than them being organic. This study reflects a relatively high ethnocentrism level of the surveyed population, especially in older individuals. Given consumer preference for km 0/local and seasonal products, and the importance of these parameters for the environment, promoting the market of such products would help to achieve some Sustainable Development Goals. This study offers a vision of the trends of Spanish consumers in relation to fruit and vegetable preferences, which can help producers and distributors to design new strategies that focus on meeting consumer demands.

Breastfeeding Practices of Women with HIV in Sub-Saharan Africa

OBJECTIVE

To identify sociodemographic factors that could enhance breastfeeding uptake among women with HIV in sub-Saharan Africa.

DESIGN

This was a secondary analysis from a retrospective cohort study using the Demographic Health Surveys (DHS) on women and HIV data from 14 sub-Saharan African countries during the period from 2010 to 2018. Our study sample encompassed women aged 15 to 49 years with HIV, with childbearing history within the 3 to 5 years preceding the survey, living in any of the countries in sub-Saharan Africa for whom breastfeeding information was available. We used an adjusted survey log binomial regression model to examine factors associated with breastfeeding among participants.

SETTING

Sub-Saharan Africa.

PARTICIPANTS

Breastfeeding women with HIV from 15 sub-Saharan African countries.

RESULTS

Of 138,920 women with HIV in sub-Saharan Africa, 49,479 (35.6%) breastfed their infants. Young women, aged 15 to 19 years (90.5%, n = 2,422) were more likely to breastfeed than those aged 25 to 29 years (13.7%, n = 5,266). Breastfeeding was more common among women who lived in rural areas (38.1%, n = 26,000) than among those in urban areas (33.2%, n = 23,479) (p < .01). The wealthiest women (43.3%, n = 13,710) breastfed more than those with the lowest economic resources (30.8%, n = 4,750) (p < .01).

CONCLUSION

Recognizing the breastfeeding issues in this individualized sub-Saharan population of women with HIV can influence the creation of more accessibility to education, resources, supplies, counseling, and support throughout the region and beyond through policy changes in health care.

Factors Influencing Consumption Intention of Insect-Fed Fish among Italian Respondents

The rise in the world's demand for fish is increasingly met by aquaculture. However, this sector still shows various criticalities in terms of sustainability of practices, first and foremost, that of feed availability. Nowadays, the use of insect meal represents one of the potential sustainable solutions, but consumption intention of fish fed with insect meal and the factors affecting it have not yet been adequately understood. This study investigates 318 Italian consumers' intentions to buy fish fed with insect meal using an extended version of the Theory of Planned Behavior, including consumers' moral attitude and sustainability consciousness as additional constructs. The results of structural equation models show that consumers' high sustainability consciousness (6.16 on a scale from 1 to 7) does not influence their consumption intention of this product. Also, the two moderating variables involved in the model, i.e., the country of origin and price sensitivity, do not significantly affect consumers' intentions. Since the analysis demonstrates that, for consumers, insect meal-fed fish conforms to their moral principles and a significant positive attitude toward this practice it could be argued that fish fed with insect meal can match the demand from consumers who feel responsible for their consumer behavior. Although the limited area of investigations and the high education of interviewed do not allow for generalizing of the results, this paper provides pivotal food for thought for companies, policymakers, and academics responding to previous research calls on understanding the role of some constructs of consumption intention and highlighting the levers on which to act to foster the consumption intention of insect-fed fish.

Who Stays, Who Moves on and the Host Population: A Picture of Adolescents' Perceived Well-Being and Risk Behaviours

The study aims to evaluate the health profile of first- and second-generation Romanian immigrants living in Italy compared to their adolescent peers in the country of origin (Romania) and the host population (Italian-borns). Analyses were performed on the 2013/2014 Health Behaviour in School-aged Children (HBSC) survey data. Romanian natives showed lower levels of health complaints and higher life satisfaction than Romanian migrants, who were similar to the host population, especially the second-generation ones. A comparable prevalence of being bullied was registered among Romanians, both native and immigrant, with significantly lower levels among Italian natives. Bullying others showed the second-generation migrants share a similar prevalence with the host population. The prevalence of liking school a lot was three times higher among the Romanian natives than among their peers living in Italy. Thanks to the HBSC data, this study is the first to examine the health of adolescent migrants from both the perspective of the host country and the population of origin. The results highlight the need for a more nuanced approach to studying immigrant populations, taking into account both the host country's perspective and the health patterns of the population of origin.

Why Do Customers Want to Buy COVID-19 Medicines? Evidence from Thai Citizens

Purchase intention has been acknowledged as an important factor influencing businesses' sales performances and sustainability. Thus, finding factors that influence purchase intention is essential to all relevant businesses. Based on the current importance of purchase intention to businesses, the main objective of this research was to investigate how country of origin, brand image, and perceived value influenced intentions to purchase COVID-19 medicines among Thai consumers. To accomplish this objective, researchers created a Google Form to survey 862 people around Thailand. However, researchers found only 653 valid data, which were analyzed through the structural equation model. The research findings revealed that perceived COVID-19 medicine value increased once the values of country of origin and brand image were highly considered by consumers. At the same time, consumers attempted to buy COVID-19 medicines for their COVID-19 treatments if the products contained high country of origin and perceived values. Finally, the perceived value was found to be a full mediator between brand image and purchase intention. In comparison, despite country of origin and perceived value being the significant factors in purchase intention, consumers' intention to purchase COVID-19 medicines depended significantly on the degree of the consumers' perceived value because perceived value contributed the highest impact on purchase intention. These results revealed that COVID-19 medicines were highly valued by many consumers because these medicines could help prevent heavy illness in consumers. As a result, consumers had a higher intention to purchase these medicines for their future COVID-19 treatments.

The Impact of Brand Awareness and Country of Origin in the Advertising Effectiveness of Greek Food Products in the United Kingdom: The Case of Greek Yogurt

The present study aims to investigate the country-of-origin effect and the branding process on the brand equity of Greek yogurt abroad, specifically in the United Kingdom. The research was carried out as a 2 × 2 experiment using a closed-ended questionnaire with the participation of a total of 400 consumers, using two Greek yogurts (branded and non-branded) as the product under study, with or without country-of-origin insignia (viz. the Greek flag) on the packaging. According to the research results, brand equity was found to be higher for the branded Greek yogurt with country-of-origin insignia among the four product categories, as reflected in its three sub-dimensions (brand awareness, loyalty, and perceived quality). It was also found that country of origin influences brand equity regardless of branding, a finding that confirms the significant effect of this factor on consumers' perceptions. This highlights the distinction between perceived quality and the specific image of the country in terms of its production experience for a specific product category. Based on these findings, Greek yogurt companies exporting abroad should lay great emphasis on developing branding strategies to strengthen their product brand, while at the same time incorporate country of origin as an indicator of the quality of their brand. The latter finding applies in particular to less well-known brands, since geographical indication (insignia) or other strategies that promote the country of origin are perceived as important informational cues for consumers.

The mediating role of product judgment and country of origin effect on health literacy and behavioral intention: A study on COVID-19 vaccines perception of Turkish consumers

This study is conducted on people in Turkey who had at least one dose of vaccination and it evaluates their differences in attitude in terms of health literacy, product judgment, the country of origin, intention to recommend and motivation to boycott. The 393 vaccine consumers were selected through convenient sampling and the data was collected through online questionnaires. The data was later analyzed by SPSS and AMOS. Normality, reliability tests and frequency analysis were conducted on the data. Afterward, a correlation was calculated using factor loadings to determine the relationship between the variables. The last was conducting the PATH analysis. Some consumers are prejudiced toward COVID-19 vaccines due to perceived distrust, hesitation, and lack of product information. Determining the prejudices of consumers, underlying causes and making inferences will provide more useful information on COVID-19 vaccines to health institutions, vaccine manufacturers, consumers and other organizations.

COVID-19 vaccines and anti-consumption: Understanding anti-vaxxers hesitancy

Anti-vaccination sentiment and vaccine hesitancy are on the rise. This is unfortunate given the world's coronavirus disease 2019 (COVID-19) pandemic response plan relies on a global vaccination program the likes of which has never been attempted. Using an anti-consumption lens, this study utilizes a qualitative approach and 53 interviews revolving around people's attitudes towards the COVID-19 vaccination plan. The findings reveal that COVID-19 vaccination hesitancy comes from two major factors: stable factors and contextual factors. Stable factors refer to factors that are consistently found in anti-vaccination movements and include political and philosophical opposition. Contextual factors refer to factors that are highly dependent on the COVID-19 situation and relates to a negative benefit to risk ratio informed by information overload and the influence of marketing phenomena such as branding and country of origin effects. Finally, theoretical and managerial contributions are offered for public policymakers and social marketers.

The Influence of Brand Image and Favorability Toward Citizens in a Product's Country of Origin on Product Evaluation: Moderating Effects of Switching Costs

This study aimed to provide practical implications for South Korean corporations seeking to enter the Chinese market. It explored the influences of brand image and favorability toward citizens in a product’s country of origin (FCPCO) on consumers’ product evaluation and repurchase intention, in addition to examining the moderating effects of procedural switching costs (economic risk costs, evaluation costs, learning costs, and set-up costs), financial switching costs (benefit loss costs and monetary loss costs), and relational switching costs (personal relationship loss costs and brand relationship loss costs) on the aforementioned influences. Although previous studies have established the relationships between some of the aforementioned variables, further research is required to determine the moderating effects of switching costs in various dimensions. Studies on the relationships of a product’s country of origin with product evaluation and repurchase intention have rarely explored FCPCO. Through a questionnaire survey, this study obtained effective data from 302 respondents. Constituted of an exploratory research design, this study adopted PLS-SEM method for empirical analysis. IPMA analysis results indicated that brand image had a stronger influence on product evaluation than FCPCO did and that FCPCO had a stronger influence on repurchase intention than brand image did. Overall, the performance of FCPCO was higher than that of brand image. Moreover, economic risk costs and brand relationship loss costs positively moderated the relationship between brand image and product evaluation; monetary loss costs and brand relationship loss costs negatively moderated the relationship between FCPCO and product evaluation. These study results could help corporations gain competitive edge.

Risk factors for SARS-CoV-2 infection and hospitalisation in children and adolescents in Norway: a nationwide population-based study

OBJECTIVE

To determine risk factors for SARS-CoV-2 infection and hospitalisation among children and adolescents.

DESIGN

Nationwide, population-based cohort study.

SETTING

Norway from 1 March 2020 to 30 November 2021.

PARTICIPANTS

All Norwegian residents<18 years of age.

MAIN OUTCOME MEASURES

Population-based healthcare and population registries were used to study risk factors for SARS-CoV-2 infection, including socioeconomic factors, country of origin and pre-existing chronic comorbidities. All residents were followed until age 18 years, emigration, death or end of follow-up. HRs estimated by Cox regression models were adjusted for testing frequency. Further, risk factors for admission to the hospital among the infected were investigated.

RESULTS

Of 1 219 184 residents, 82 734 (6.7%) tested positive by PCR or lateral flow tests, of whom 241 (0.29%) were admitted to a hospital. Low family income (adjusted HR (aHR) 1.26, 95% CI 1.23 to 1.30), crowded housing (1.27, 1.24 to 1.30), household size, age, non-Nordic country of origin (1.63, 1.60 to 1.66) and area of living were independent risk factors for infection. Chronic comorbidity was associated with a slightly lower risk of infection (aHR 0.90, 95% CI 0.88 to 0.93). Chronic comorbidity was associated with hospitalisation (aHR 3.46, 95% CI 2.50 to 4.80), in addition to age, whereas socioeconomic status and country of origin did not predict hospitalisation among those infected.

CONCLUSIONS

Socioeconomic factors, country of origin and area of living were associated with the risk of SARS-CoV-2 infection. However, these factors did not predict hospitalisation among those infected. Chronic comorbidity was associated with higher risk of admission but slightly lower overall risk of acquiring SARS-CoV-2.

Consumer Preferences and Willingness to Pay for Mud Crabs in Southeast Asian Countries: A Discrete Choice Experiment

The mud crab (Scylla serrata) is an economically important species found in the mangroves and estuaries of tropical countries and is a popular seafood product in the coastal areas of Southeast Asian markets. The aim of this study is to identify factors affecting consumer preference of mud crabs, and to understand consumers’ willingness to pay (WTP) for these factors in a Singapore market where imported mud crabs from other Asian countries are sold. The results showed that the country of origin matters to participants, affecting purchasing decisions, and consumers were willing to pay approximately 16.48 SGD (11.49 USD, the average price of four shops: 35.55 USD/kg for one mud crab) more if the mud crabs were from Sri Lanka if compared with Indonesian or Cambodian mud crabs. Moreover, consumers were willing to pay 25.08 SGD (17.48 USD) more if the mud crabs were alive and 13.40 SGD (9.34 USD) less if the mud crabs were frozen compared with fresh, but not alive, mud crabs. Furthermore, consumers’ preference in mud crab was associated with the consumers’ religion. Some groups of consumers preferred female mud crabs with eggs over male mud crabs, while other groups preferred male crabs. The results identified diverse consumer preference of mud crabs and, therefore, could provide new insights that are useful for sustainable consumption of mud crabs in the region.

The Impact of "Wine Country of Origin" on the Perception of Wines by South African and French Wine Consumers: A Cross-Cultural Comparison

Culture is an important factor that influences how marketing interacts with food choice. This study aims at exploring the effect of consumers' Country of Origin (COO) on wine representations and perception using Chenin blanc as a model. The first objective was to evaluate the role of origin in the construction of the representation. We used the theoretical framework of social representation to compare South African (SA) and French consumers' representations via a word association task. The results indicated that SA representations are dominated by consumers' experience of the wine (sensory and emotional dimensions), whereas French representations are dominated by the wine itself, in particular its origin and mode of consumption. The second objective was to evaluate the effect of origin on wine categorization in two conditions: with and without information concerning the two geographical origins of the samples. Results showed that providing information on the origin of the wines affected French participants more than SA participants. In both conditions, the groups of wines formed in the sorting tasks by SA participants were based on sensory descriptors and appeared not to be impacted by the information on origin. In contrast, providing information on the origin of the wines to French participants led to an increased use of the words "Loire", "South Africa" and "familiar" suggesting a different sorting strategy more deliberately based on the origin of the wines. Our findings have important implications for the marketing and export activities within the wine industry.

Physicochemical and Sensory Assessments in Spain and United States of PGI-Certified Ternera de Navarra vs. Certified Angus Beef

The physicochemical and sensory differences between the PGI-Certified Ternera de Navarra (CTNA) (Spanish origin) and Certified Angus Beef (CAB) (US origin) were assessed in Spain and the USA. To characterize the carcasses, the ribeye areas (REAs), and marbling levels were assessed in both testing places. Twenty striploins per certified beef program were used as study samples. For sensory analysis, the striploins were vacuum packaged and aged for 7 days at 4 °C and 85% RH in each corresponding laboratory. Thereafter, the samples were half cut and frozen. One of the halves was shipped to the other counterpart-testing place. The fat and moisture percentage content, Warner Bratzler Shear Force (WBSF), and total and soluble collagen were tested for all the samples. The CAB carcasses had smaller REAs (p < 0.0001) and exhibited higher marbling levels (p < 0.0001). The CAB striploins had a higher fat content (p < 0.0001) and required lower WBSF (p < 0.05) than the CTNA samples. Trained panelists rated the CAB samples as juicer (p < 0.001), more tender/less tough (p < 0.0001), and more flavorful (p < 0.0001) than the CTNA counterparts. This study shows that beef from both countries had medium-high tenderness, juiciness, and beef flavor scores and very low off-flavor scores. Relevant differences found between the ratings assigned by the Spanish and the US panelists suggest training differences, or difficulties encountered in using the appropriate terminology for defining each sensory attribute. Furthermore, the lack of product knowledge (i.e., consumption habits) may have been another reason for such differences, despite the blind sensory evaluation.

The determinants of immigrant health insurance in the United States: Understanding the role of health care in origin societies

We examine how immigrants' health insurance in the United States is shaped by institutional traits of the health care systems in their origin societies. Conditional on a wide range of individual, country-of-origin, state-level, and temporal controls, we find the affordability of health care back home helps explain immigrants' US health coverage. Specifically, low- and middle-income migrants from countries with less affordable health care are more likely to get private insurance once in the United States and, correspondingly, less likely to have public coverage, relative to migrants from countries with more affordable care. The relationship conforms to multiple hypotheses. As predicted by the institutional beliefs hypothesis, migrants from countries with less affordable care might anticipate equally expensive health services in the United States and, in turn, insure themselves against high medical bills. Likewise, as predicted by the endogenous preferences hypothesis, migrants from countries with less affordable care might be accustomed to paying more for health care and, in turn, be less reluctant to pay for private health insurance. Overall, the findings underscore the relevance of migrants' past health care experiences in their origin societies in informing their health insurance in the United States even years after migration.

Consumer Preferences for Origin and Organic Attributes of Extra Virgin Olive Oil: A Choice Experiment in the Italian Market

The paper investigates Italian consumers’ behavior towards characteristics of extra virgin olive oil, in particular organic production methods and geographical origin. On the basis of the existing literature, the concepts of sustainability of food systems, diets, and the olive oil supply chain are analyzed. A choice experiment (CE), using a face-to-face questionnaire with over 1000 participants, was conducted to quantify the willingness to pay (WTP) for these two attributes. Findings show positive preference for origin attributes, while the organic attribute is not highly valued. The article also offers some perspectives on future research to improve the competitiveness and sustainability of the Italian olive oil supply chain.

COVID-19 Tests the Limits of Biodiversity Laws in a Health Crisis: Rethinking "Country of Origin" for Virus Access and Benefit-sharing

The COVID-19 pandemic raises serious questions about the operation of international agreements for accessing and sharing viruses potentially delaying emergency responses. The access and benefit-sharing (ABS) frameworks under the United Nations' Convention on Biological Diversity and its Nagoya Protocol apply to the collection and use of the COVID-19 pathogen SARS-CoV-2. These frameworks aim to ensure countries of origin reap some of the benefits from the use of their resources. Using real-world examples, we demonstrate conceptual and definitional ambiguities relating to "country of origin" that make not only operationalising the ABS scheme for biodiversity conservation and sustainable use objectives difficult but may also undermine public health emergency responses. Understanding how COVID-19 fits (or does not fit) within ABS laws is a valuable exercise for international policy-makers trying to determine how best to operationalise pathogen ABS, an issue currently under examination at the World Health Organization and critical to responding to pandemics.

Joint Associations of Maternal-Fetal APOL1 Genotypes and Maternal Country of Origin With Preeclampsia Risk

RATIONALE & OBJECTIVES

Preeclampsia, which disproportionately affects Black women, is a leading cause of preterm delivery and risk for future hypertension and chronic kidney disease (CKD). Apolipoprotein L1 (APOL1) kidney risk alleles, common among Black individuals, contribute substantially to CKD disparities. Given the strong link between preeclampsia and CKD, we investigated whether maternal and fetal APOL1 risk alleles can jointly influence preeclampsia risk, and explored potential modifiers of the association between APOL1 and preeclampsia.

STUDY DESIGN

Nested case-control study.

SETTING & PARTICIPANTS

426 Black mother-infant pairs (275 African Americans and 151 Haitians) from the Boston Birth Cohort.

EXPOSURE

Maternal and fetal APOL1 risk alleles.

OUTCOMES

Preeclampsia.

ANALYTICAL APPROACH

Logistic regression models with adjustment for demographic characteristics were applied to analyze associations between fetal and maternal APOL1 risk alleles and risk of preeclampsia and to investigate the effects of modification by maternal country of origin.

RESULTS

Fetal APOL1 risk alleles tended to be associated with an increased risk of preeclampsia, which was not statistically significant in the total genotyped population. However, this association was modified by maternal country of origin (P<0.05 for interaction tests): fetal APOL1 risk alleles were significantly associated with an increased risk of preeclampsia among African Americans under recessive (odds ratio [OR], 3.6 [95% CI, 1.3-9.7]; P=0.01) and additive (OR, 1.7 [95% CI, 1.1-2.6]; P=0.01) genetic models but not in Haitian Americans. Also, maternal-fetal genotype discordance at the APOL1 locus was associated with a 2.6-fold higher risk of preeclampsia (P<0.001) in African Americans.

LIMITATIONS

Limited sample size in stratified analyses; self-reported maternal country of origin; pre-pregnancy estimated glomerular filtration rate (eGFR) and proteinuria data in mothers were not collected; unmeasured confounding social and/or environmental factors; no replication study.

CONCLUSIONS

This study supports the hypothesis that fetal APOL1 kidney risk alleles are associated with increased risk for preeclampsia in a recessive mode of inheritance in African Americans and suggests that maternal-fetal genotype discordance is also associated with this risk. These conclusions underscore the need to better understand maternal-fetal interaction and their genetic and environmental factors as contributors to ethnic disparities in preeclampsia.

Consumer Misuse of Country-of-Origin Label: Insights from the Italian Extra-Virgin Olive Oil Market

Providing information to consumers through the label is a means for food companies to inform consumers about product’s attributes, including the country of origin (COO). In the EU, COO labeling has been made mandatory for several categories of food products, to enable consumers to make informed choices at the point of sale. In particular, Regulation (EU) No 29/2012 has introduced a mandatory country-of-origin labeling system for extra virgin olive oil (EVOO). In the present study, conducted in Italy, we test whether there is a price differential associated with the COO information for EVOO. To this end, we employ a hedonic price model and data about the purchase of EVOO products collected from 982 consumers at the supermarket checkout. Having interviewed these consumers, we also assess the share of EVOO consumers that correctly identify the country of origin of the product purchased. Our findings point out that, in Italy, the EVOO with domestic origin, indicated on the label, benefits of a premium price equal to +35% compared to the product labeled as blend of European EVOOs, while a discount of −10.8% is attached to EVOOs from a non-European origin. A significant share of consumers in our sample (19.04%) is, however, unable to correctly identify the origin of the EVOO purchased. This label misuse mostly occurs among consumers who report that they had purchased Italian EVOO, while they had actually purchased a blend of European EVOOs. Female and more highly educated consumers are less likely to misuse label information about the product’s origins.

Consumers' Willingness to Pay for Imported Milk: Based on Shanghai, China

Against the backdrop of the continuous large-scale growth of imported milk in China, in this research 310 consumers in Shanghai were used as a sample, and a choice experiment was conducted to study consumer preference and willingness to pay for imported milk. The following product attributes were included: nutrition claim, fat content, flavor, country of origin, and price. Our results show that, excepting price, consumers consider flavor the most important attribute, followed by nutrition claim, fat content, and country of origin. Consumers can be delineated into four segments based on consumer preference for the attributes of imported milk: “nutrition claim seekers” are willing to pay the highest price for imported milk with nutrition claims, “indifferent” consumers pay little attention to imported milk attributes, “flavor-oriented” consumers have a strong preference for strawberry-flavored imported milk, and “price-sensitive” consumers weigh the price when choosing imported milk.

Fungal food spoilage of supermarkets' displayed fruits

Background and Aim:

Post-harvest fungal infection of fruits and vegetables is mainly caused by fungal pathogens that can be harmful to both human and animals as they produce mycotoxins, post-harvest diseases in fruits and vegetables are a serious problem that results in the loss of a large percentage of crops reaching 50% in some fruits. This study aims at screening the post-purchasing shelf-life of four highly consumed fruits and vegetables and at identifying the fungal strains behind their spoilage in Qatar.

Materials and Methods:

Fruits and vegetables were collected from the market to study their post-purchasing shelf-life and to identify the fungal types involved in samples rotting. Factors that affect samples’ shelf-life were also analyzed.

Results:

A total of 73 fungal isolates were isolated and identified, with the highest percentage of Penicillium (21.9%) followed by Rhizopus (17.8%). Interestingly, many mycotoxins producing and diseases inducing fungi were identified in this study; this includes Rhizopus, Aspergillus, Penicillium, Alternaria, Fusarium, Cladosporium, Botrytis, Geotrichum, and Colletotrichum. Statistical analysis shows that different fruits have significantly different shelf-life and different predispositions for spoilage. In many cases, a strong relationship was shown between the fungal types isolated and the country of origin of the fruit. Finally, the price of the commodity did not have a significant effect on its contamination level nor did the market from which the sample was purchased. This indicates that the fruit displaying methods in Qatar do not affect their contamination level.

Conclusion:

The study is among the first reports about fungal types involved in fruits and vegetables rotting in Qatar and it highlights the strong link between spoiling fungi and their country of origin.

Minerals and Heavy Metals in the Whole Raw Milk of Dairy Cows from Different Management Systems and Countries of Origin: A Meta-Analytical Study

The objective of this meta-analytical study was to investigate selected macrominerals, microminerals, and toxic heavy metals in the bovine whole-raw-milk (WRM) samples of published data. An analytical data set was constructed from 72 different studies from 37 countries with two types of production systems: a conventional production system (CPS) and an organic production system (OPS) compared with commercially available or retail-store-available milk (COM). Results of the meta-analytical study showed differences in the concentrations of macrominerals. Concentrations of Ca, Mg, K, and P were greater in the CPS samples, whereas Na was greater in the COM samples ( P < 0.05). Data also demonstrated that concentrations of microminerals like Cu, I, Fe, Mn, Se, and Zn in the organic WRM were lower ( P < 0.05) compared with the milk from CPS. The highest concentration of Ni was reported for COM ( P < 0.05); however, this value was below the minimum-risk level (MRL). Concentrations of heavy metals like As and Ni were greater in CPS milk than those in organic milk ( P < 0.05). In addition, there were greater concentrations of Cd and Pb in the WRM from CPS versus that from the organic farms. Concentration of Al was lowest in the OPS milk versus Al in the CPS which was 6.5-fold greater than in organic milk. The amount of Hg was below the MRL of 0.01 μmol/L for all production systems. A high variability was observed in the published data regarding the country of origin. Raw milk originating from Europe and North America was characterized by concentrations of macro- and microminerals below the MRLs as compared with that from specific countries, which had some minerals above the MRLs. For example, concentrations of Pb were above the MRL in the milk samples from Brazil, Croatia, Egypt, Mexico, Nigeria, Palestine, Romania, Serbia, and Turkey. Moreover, data from this study indicate that organic dairy farms are characterized by lower concentrations of toxic heavy metals in the WRM compared with those from CPS dairy farms.

Belgian citizens' and broiler producers' perceptions of broiler chicken welfare in Belgium versus Brazil

New EU regulations require more stringent country-of-origin labeling, while imports of broiler meat from non-EU countries are increasing. In light of these trends, we have studied citizens' and producers' perceptions of broiler meat originating from Belgium versus Brazil and their perception of broiler production in Belgium versus Brazil. A particular focus was the association between country of origin and perceived level of animal welfare. We also investigated the perception of scaling-up and outdoor access in terms of perceived level of animal welfare. Cross-sectional survey data was collected among Flemish citizens (n = 541) and broiler producers (n = 114). In accordance with literature on general farm animal welfare, both stakeholder types claimed to allocate great importance to broiler welfare and generally agreed with the Welfare Quality model of broiler welfare. Citizens disagreed with the producers that 1) consumers are not willing to pay more for higher welfare products, 2) that broilers suffer little, 3) that broiler welfare in current Belgian production units is generally non-problematic, 4) that scaling-up production units would not have a positive impact on profitability nor a profoundly negative impact on broiler welfare, and 5) that the impact of providing broilers with outdoor access is negative for consumers, farmers, and broilers. Country of origin had a strong influence on the perception of both broiler production and broiler meat. Belgian citizens, and producers (much more than citizens) considered nearly all aspects related to broiler production and broiler meat to be significantly superior for chicken produced in Belgium compared to Brazil. Further research should focus on how these perceptions influence purchase intentions and production decisions. Future avenues for research are to quantify market opportunities for country-of-origin labeling and to investigate to which extent stakeholders' perceptions correspond with reality.

Binge Drinking and Risk Taking Behavior Among Adolescent Females in Israel

PURPOSE

This prospective study examined binge drinking and alcohol-related problem behavior among Israeli adolescent females attending public school or a residential facility for substance abuse treatment.

PROBLEM

Scant information is known about adolescent females, especially those with high-risk (e.g., school dropout and immigrant origin) characteristics.

METHODS

The authors hypothesized that school, residential treatment, and mothers' country of origin status are associated with binge drinking and problem behavior.

FINDINGS

Females in residential treatment reported higher levels of binge drinking and problem behavior as expected. However, country of origin was not a significant factor differentiating the female adolescents in school or a residential facility. Logistic regression points to current cigarette smoking, ease of purchasing alcohol, unsupervised night activity, low religiosity, and being physically threatened as predictors of binge drinking and problem behavior.

CONCLUSION

The lack of differences based on country of origin status points to acculturation as a possible reason for the homogeneity. Further research is needed to study the impact of acculturation as well as monitor the alcohol use patterns and problems of adolescents over time and across locations to address prevailing needs.

Isotopic and Elemental Composition of Roasted Coffee as a Guide to Authenticity and Origin

This study presents the stable isotopic and elemental compositions of single-origin, roasted coffees available to retail consumers. The δ(13)C, δ(15)N, and δ(18)O compositions were in agreement with those previously reported for green coffee beans. The δ(15)N composition was seen to be related to organic cultivation, reflected in both δ(2)H and δ(18)O compositions. The δ(13)C composition of extracted caffeine differed little from that of the bulk coffee. Stepwise discriminant analysis with jackknife tests, using isotopic and elemental data, provided up to 77% correct classification of regions of production. Samples from Africa and India were readily classified. The wide range in both isotopic and elemental compositions of samples from other regions, specifically Central/South America, resulted in poor discrimination between or within these regions. Simpler X-Y and geo-spatial plots of the isotopic data provided effective visual means to distinguish between coffees from different regions.

Genotyping of velvet antlers for identification of country of origin using mitochondrial DNA and fluorescence melting curve analysis with locked nucleic acid probes

Velvet antlers are used medicinally in Asia and possess various therapeutic effects. Prices are set according to the country of origin, which is unidentifiable to the naked eye, and therefore counterfeiting is prevalent. Additionally, antlers of the Canadian elk, which can generate chronic wasting disease, are prevalently smuggled and distributed in the market. Thus, a method for identifying the country of origin of velvet antlers was developed, using polymorphisms in mitochondrial DNA, fluorescence melting curve analysis and analysis of locked nucleic acids (LNA). This combined method is capable of identifying five genotypes of velvet antlers in a single experiment using two probes. It also has advantages in multiplexing, simplicity and efficiency in genotyping, when compared to real-time PCR or microarrays. The developed method can be used to improve identification rates in the velvet antler market and, by extension, research based on polymorphisms in DNA sequences.

Higher risk for adverse obstetric outcomes among immigrants of African and Asian descent: a comparison study at a low-risk maternity hospital in Norway

BACKGROUND

Immigrants have higher risks for some adverse obstetric outcomes, and 40 percent of women giving birth at the low-risk maternity ward in Baerum Hospital, Norway, are immigrants. This study compared obstetric outcomes between immigrants and ethnic Norwegians giving birth in a low-risk setting.

METHODS

This was a population-based study linking the Medical Birth Registry of Norway to Statistics Norway. The study included the first registered birth during the study period to immigrant and ethnic Norwegian women at Baerum Hospital from 2006 to 2010. The main outcome measures were onset of labor, operative vaginal delivery, cesarean delivery, episiotomy, postpartum bleeding > 500 mL, epidural analgesia, labor dystocia, gestational age, meconium-stained liquor, 5-minute Apgar score, birthweight, and transfer to a neonatal intensive care unit.

RESULTS

A total of 11,540 women originating from 141 countries were divided into seven groups. Compared with Norwegians, women from East, Southeast, and Central Asia had increased risk for operative vaginal delivery, postpartum bleeding, and low Apgar score. The African women had increased risk for postterm birth, meconium-stained liquor, episiotomy, operative vaginal delivery, emergency cesarean delivery, postpartum bleeding, low Apgar score, and low birthweight. Women from South and Western Asia had increased risk for low birthweight.

CONCLUSION

Obstetric outcomes of immigrants differ significantly from those of Norwegians, even in a low-risk maternity unit. Thus, immigrant women would benefit from more targeted care during pregnancy and childbirth, even in low-risk settings.

Stable isotope and chemical compositions of European and Australasian ciders as a guide to authenticity

This paper presents a data set derived from the analysis of bottled and canned ciders that may be used for comparison with suspected counterfeit or substitute products. Isotopic analysis of the solid residues from ciders (predominantly sugar) provided a means to determine the addition of C4 plant sugars. The added sugars were found to comprise cane sugar, high-fructose corn syrup, glucose, or combinations. The majority of ciders from Australia and New Zealand were found to contain significant amounts of added sugar, which provided a limited means to distinguish these ciders from European ciders. The hydrogen and oxygen isotopic compositions of the whole ciders (predominantly water) were shown to be controlled by two factors, the water available to the parent plant and evaporation. Analysis of data derived from both isotopic and chemical analysis of ciders provided a means to discriminate between regions and countries of manufacture.

U. S. consumer perceptions of U. S. and Canadian beef quality grades

A U.S. consumer (n = 642) study (Baltimore, MD; Phoenix, AZ; and Lubbock, TX) was conducted to compare consumer sensory scores of U.S. beef (83 USDA Choice [Choice] and 96 USDA Select [Select]) and Canadian beef (77 AAA and 82 AA) strip loins. Strip loins (n = 338) were obtained from beef processors in Canada and the United States and were wet aged until 21 d postmortem at 2°C. Marbling scores were assigned at 21 d and loins were paired according to quality grades and marbling score. Strip loins were fabricated into 2.54-cm thick steaks; steaks were vacuum packaged and frozen until further evaluations. Proximate analysis was performed to compare fat, moisture, and protein. Choice and Canadian AAA had similar marbling scores and intramuscular fat. Both Choice and Canadian AAA had greater (P < 0.05) marbling scores and intramuscular fat than Canadian AA, but Select strip loins had intermediate values that were not different from any of the other grades (P > 0.05). Consumers' opinions did not differ when comparing equivalent grades (Choice with Canadian AAA and Select with Canadian AA), but they rated Choice and Canadian AAA more palatable than Select and Canadian AA for all sensory attributes (P < 0.05). Regarding percentage of acceptability and likelihood to buy score, consumers indicated a preference and greater probability to buy (P = 0.001 and P = 0.004, respectively) strip loin steaks from higher quality grade carcasses (Choice and Canadian AAA) than lower quality grade carcasses (Select and Canada AA). Additionally, consumers gave their opinion of Canadian beef, where its quality and safety were rated as "good" to "excellent" for both attributes (76.72% and 88.36%, respectively; P < 0.05), feeling confident in beef that is imported from Canada. In the same way, consumers indicated that country-of-origin labeling was a minimal factor influencing their beef steak purchasing decisions. Results from this consumer study indicated U.S. consumers could not differentiate between U.S. and Canadian beef within comparable quality grades; however, strip loin steaks from higher quality grades were more palatable than lower quality grades according to consumer scores for eating quality traits.

Stillbirth and infant death among generations of Pakistani immigrant descent: a population-based study

OBJECTIVE

To examine the risk of stillbirth and infant death among offspring of Pakistani-born and Norwegian-born women of Pakistani immigrant descent.

DESIGN

Population-based study linking the Medical Birth Registry of Norway to immigration data from Statistics Norway.

SETTING

Norway.

POPULATION

Births to women of Pakistani immigrant descent classified as Pakistani-born (n = 8814) or Norwegian-born (n = 1801), and to the host population of Norwegian descent (n = 712 430) from 1995 to 2010.

METHODS

The relative risk of stillbirth and infant death by country of descent and birth was estimated by odds ratios with 95% confidence intervals (95% CI) using logistic regression.

MAIN OUTCOME MEASURES

Stillbirth and infant death.

RESULTS

Risk of stillbirth was highest in the Pakistani-born group (7.4/1000, 95% CI 5.7-9.4) followed by the Norwegian-born group (5.0/1000, 95% CI 1.7-8.3) and finally the host population (3.5/1000, 95% CI 3.3-3.6). Relative to the host population, risk of stillbirth was higher in both Pakistani-born (odds ratios 2.8, 95% CI 2.2-3.6) and Norwegian-born (odds ratios 2.2, 95% CI 1.1-4.2) groups, after adjustment for year of birth, age, parity and residence. For infant death, absolute risks were 6.9/1000 (95% CI 5.2-8.8), 5.6/1000 (95% CI 2.7-10.2), and 2.9/1000 (95% CI 2.7-3.0), with adjusted odds ratios of 2.8 (95% CI 2.1-3.7) and 2.4 (95% CI 1.3-4.6), respectively.

CONCLUSIONS

An elevated risk of stillbirth and infant death persists across generations of Pakistani immigrant descent living in Norway. While translating into few excess deaths, the elevated risks should be taken into account by obstetric and pediatric care providers.
