RESUMEN

In most low- and middle-income countries, milk is produced by smallholders, thereby contributing to the livelihood of their households. With the increasing importance of milk production in these countries, it is essential that milk quality is of a high level to ensure a safe product for consumers. It is, however, unclear whether smallholder dairy farmers are aware of the quality of their milk. The aim of this cross-sectional study was to gain insight on Indonesian smallholder dairy farmer awareness of milk quality parameters and to identify factors associated with the total plate count (TPC) and somatic cell count (SCC). A stratified sampling method was used to select smallholder farms in 4 districts in West Java, Indonesia, that were interviewed between August and September 2017. Factors putatively associated with awareness of TPC were investigated with multinomial regression models, whereas a Firth-type logistic regression was applied to identify factors associated with SCC awareness. Of the total 600 farmers surveyed, 264 (44%), 109 (18%), 170 (28%), 111 (19%), and 23 (4%) farmers were aware of TPC, total solid, fat content, milk density, and SCC, respectively, but did not know its value. Those that were conceptually aware of these quality parameters were generally unaware of their value. Furthermore, this study revealed that the following variables were significantly associated with dairy farmers' awareness of TPC: cooperative to which the farmer belonged, distance to neighboring dairy farmer, technology adoption index, TPC as the most important quality factor for the buyer, milk production information from cooperatives, and cow health information from veterinarians. Similarly, cooperative, dairy business experience, and milk quality test adoption were significantly associated with dairy farmers' awareness of SCC. Cooperative was the only variable that was significant in both final statistical models. This indicates that cooperatives play an important role in increasing farmer awareness of milk quality parameters in these smallholder dairies. This may be valid for other regions in the world also where milk production is dominated by smallholder dairy farmers.

RESUMEN

OBJECTIVE: To examine the association between consumption of western foods purchased and consumed away from home and measures of nutrition quality: average daily caloric intake and macronutrient (carbohydrates, fat and protein) shares, for urban consumers in Vietnam, a country undergoing economic transition. DESIGN: Cross-sectional observational data were collected using household surveys and 24-h food diaries. Outcome variables were individual average daily caloric intake and shares of calories from macronutrients: carbohydrates, fat and protein. The key explanatory variable was individual daily share of calories from western food purchased and consumed away from home. Ordinary least squares and multivariate regression analyses were used to examine the association between the outcome variables: caloric intake and macronutrient shares and the share of calories from western food consumed away from home. SETTING: Hanoi and Ho Chi Minh City in Vietnam. PARTICIPANTS: In total, 1685 households and 4997 individuals, including adults (aged $$ \ge $$ 18 years), adolescents (aged 10-17 years) and children (aged 0-9 years). RESULTS: The share of calories from western food away from home was significantly associated with higher caloric intake among male and female adults (P < 0·01), adolescents (P < 0·01) and male children (P < 0·10) and was associated with higher shares of fat for male and female adults (P < 0·01), adolescents (P < 0·01) and male children (P < 0·01). CONCLUSIONS: Policymakers must be conscious of the numerous factors associated with poor nutrition quality, especially in younger Vietnamese individuals. Relevant interventions targeting at risk groups are required if nutrition improvement is a long-term goal.

RESUMEN

Addiction is a chronic, relapsing brain disease. It is not the same as physical dependence (i.e., withdrawal) and tolerance, but is characterized by loss of control over the use of the substance, continued use despite consequences, compulsive use, and cravings. Addiction involves functional changes to brain pathways involved in reward, stress and learning, and these changes can last a long time after the addictive substance is no longer used. Repeated interruption of normal brain function from repetitive use of addictive substances can hijack normal reward mechanisms resulting in fundamental alterations in brain structure and function. Over time, addictive substances can bring about a false fixed prediction error that cannot be rectified during learning. And, for individuals who develop an addiction, initial impulsive drug use progresses to compulsive drug use and this progression also has neurobiological underpinnings. Drug addiction is partly heritable, although there is no single gene coding specifically for the disease of addiction. Genetic factors contribute to a vulnerability to develop both addiction and addiction comorbidities, and play an appreciable role in responses to and metabolism of addictive substances, and most likely, the experience of rewarding effects. Patients with pain who are addicted to opioids have, in addition to the pain disorder, a chronic relapsing brain disease that can be life-threatening. Addiction can be treated and controlled, but not cured. Treatment of pain in individuals with addiction is a complex clinical challenge. Holistic assessment, interprofessional approaches, use of established guidelines, and non-pharmacological complementary modalities are needed.

RESUMEN

There is a growing trend of consumers in developed countries substituting alternative protein sources for meat and purchasing meat products with specific production-system related credence attributes. This study of Australian meat consumers identifies consumer segments with varying levels of willingness to make the following changes to their protein consumption: reduce meat consumption, follow a meat-free diet most of the time, avoid meat consumption altogether, and follow a strict plant-based diet (i.e., stop eating all animal-products). Segments are characterised, and predictors of segment membership are determined. Discrete Factor analysis, based on a nationally-representative sample of 287 Australian meat consumers surveyed in 2016, identified four unique segments. Findings show that 46% of consumers are not willing to make any changes to their meat/protein consumption ('Committed Meat Eaters'), 22% are willing to reduce meat consumption ('Willing Meat Reducers'), 15% are willing to stop meat consumption/consume plant-based protein foods only ('Prospective Veg*ns'), and 17% are undecided about future change ('Undecided Meat Eaters'). The key factor differentiating Committed Meat Eaters from other segments is the perception that food choices are inadequate in meat-free diets. Committed Meat Eaters are also less likely to believe livestock farming contributes to climate change, and to report a recent reduction in the consumption of at least one type of meat than are Willing Meat Reducers and Prospective Veg*ns. These findings are expected to be of interest to individuals and organisations who may play a role in meeting current and future consumer demand for meat and alternative protein products.

RESUMEN

We examined intrahousehold decision making with respect to household investment in portfolios of future rice varietal trait improvements (VTIs) to increase farm households' livelihoods in Nueva Ecija, Philippines. Investment decisions were elicited using an experimental methodology based on investment games. In the investment game, couples from rice farming households were given the opportunity to invest in public rice breeding. They selected, first individually, and then jointly, a replacement rice variety to improve upon and were then asked to allocate a research endowment fund to a portfolio of VTIs. We developed a novel indicator of women's intrahousehold decision-making power (WIDMP) based on the relative Euclidean distances between the individual and joint VTI portfolios. We found that WIDMP is normally distributed; and that, on average, women had almost equal (48%) decision-making power as men (52%), revealing almost perfect gender equity in investment decision making in rice breeding. Women were slightly more empowered if they were engaged in off-farm employment and were less experienced in farming. More empowered women had a higher discount factor and based their investment decisions on anticipated future trends, rather than current or past experience. The findings not only highlight the importance of considering gender roles in technology design, adoption and extension programs, but also have broader implications in terms of women empowerment programs. Consistent with the Sustainable Development Goals (SDGs), our evidence suggests that education and training programs need to be paired with investments generating off-farm employment opportunities to effectively increase women's bargaining power in the household.

RESUMEN

BACKGROUND: Pain, depression, anxiety, sleep disturbances, and constipation were reported in different symptom clusters at different stages of breast cancer. Managing symptom clusters rather than individual symptoms can improve performance status. AIM: The study examined the effect of pain symptom cluster (pain and constipation) on performance when mediated by the psychoneurological symptom cluster (depression, anxiety, and sleep disturbances) using age as a moderator. DESIGN: A secondary analysis. SETTINGS: Palliative care center at a tertiary medical center in northeast Ohio. PARTICIPANTS: Eighty-six women diagnosed with advanced breast cancer. METHOD: A quantitative cross-sectional approach. RESULTS: Ordinal logistic regression showed that pain symptom cluster did not have a significant mediation effect on performance. Odds ratio indicated that subjects with pain symptom cluster were 63% more likely to be bedridden (odds ratio = 1.63, confidence interval = .69-3.84). Women who reported pain symptom cluster were 5% more likely to have psychoneurological symptom cluster (odds ratio = 1.05, confidence interval = .400-2.774). Stratified analysis of age showed no differences in performance. Post-hoc analysis showed that the components of pain symptom cluster had a significant effect on psychoneurological symptom cluster (odds ratio: 3 [1.18-7.62]). CONCLUSIONS: Pain, constipation, depression, anxiety, and sleep disturbances were highly prevalent in women with advanced breast cancer. However, they tended to cluster in different symptom clusters. Although some findings were not significant, they all supported the direction of the tested hypotheses. Variations in symptom clusters research, including methodology, instruments, statistical tests, and chosen symptom cluster correlation coefficient, should be addressed.

RESUMEN

This study aims to aid in the development of more effective healthy eating intervention strategies for pregnant women by understanding the relationship between healthy eating intention and actual eating behaviour. Specifically, the study explored whether Theory of Planned Behaviour (TPB) constructs [attitude, subjective-norm, perceived-behavioural-control (PBC)] and additional psychosocial variables (perceived stress, health value and self-identity as a healthy eater) are useful in explaining variance in women's 1) intentions to consume a healthy diet during pregnancy and 2) food consumption behaviour (e.g. adherence to food group recommendations) during pregnancy. A cross-sectional sample of 455 Australian pregnant women completed a TPB questionnaire as part of a larger comprehensive web-based nutrition questionnaire. Women's perceived stress, health value and self-identity as a healthy eater were also measured. Dietary intake was assessed using six-items based on the 2013 Australian Dietary Guidelines. Hierarchical multiple linear regression models were estimated (significance level <0.05), which explained 70% of the variance in healthy eating intention scores and 12% of the variance in adherence to food group recommendations. TPB constructs explained 66% of the total variance in healthy eating intention. Significant predictors of stronger healthy eating intention were greater PBC and subjective norm, followed by positive attitude and stronger self-identity as a healthy eater. Conversely, TPB constructs collectively explained only 3.4% of total variance in adherence to food group recommendations. These findings reveal that the TPB framework explains considerable variance in healthy eating intention during pregnancy, but explains little variance in actual food consumption behaviour. Further research is required to understand this weak relationship between healthy eating intention and behaviour during pregnancy. Alternative behavioural frameworks, particularly those that account for the automatic nature of most dietary choices, should also be considered.

RESUMEN

OBJECTIVE: To assess dietary intake of pregnant women against the Australian Dietary Guidelines with respect to the Five Food Group recommendations and determine predictors of adherence to the recommendations. DESIGN: Cross-sectional web-based survey. Data were analysed using descriptive statistics and logistic regression. SETTING: Pregnant women living in Australia. A national sample was recruited using an online panel provider and a South Australian sample was recruited through the antenatal clinic of a large public maternity hospital. SUBJECTS: A total of 857 pregnant women. RESULTS: Fifty-six per cent, 29% and less than 10% of women met the recommendations for the fruit, dairy and other core food groups, respectively. None of the women met the recommendations for all Five Food Groups. Women who were born overseas and who were less physically active pre-pregnancy were less likely to adhere to the fruit and dairy recommendations. Women who smoked during pregnancy, were overweight pre-pregnancy and had lower household incomes were also less likely to meet the fruit recommendations; and women living in metropolitan areas were less likely to meet the vegetable recommendations. Sixty-one per cent believed their diet during this pregnancy was healthy. CONCLUSIONS: The majority of pregnant women in Australia perceive their diets to be healthy yet they do not consume the recommended daily servings from the Five Food Groups. Intervention strategies are warranted, particularly those that increase women's ability to evaluate their diet and also encourage positive dietary changes. These strategies may increase adoption of dietary guidelines and optimise pregnancy and other long-term health outcomes.

RESUMEN

Chronic non-cancer pain (CNCP) is a disease that affects adults in their child-rearing years and is often incurable and of indefinite duration. Children and adolescents who live with parental CNCP can endure multiple adversities and experience subsequent emotional and somatic difficulties. Resilience is the ability to overcome adversity and even experience growth. This study is a secondary analysis of qualitative data, which sought to gain a deeper understanding of the ways in which children and adolescents rebound and grow from experiences living with parents who suffer with CNCP. Young adult children (N=30) of parents with CNCP were interviewed. Content analysis yielded five ways in which their experiences led to areas of positive growth: (a) expanded ways of understanding; (b) cultivated a strong character; (c) aided in the development of important skills; (d) instilled a commitment to live well, and; (e) nurtured spirituality. Clinicians who work with children and adolescents whose parents are disabled with CNCP can create environments that foster resilience and serve as a guide by helping these youth recognize potentials that have not yet been actualized and promoting positive change and growth over time.

RESUMEN

A qualitative study explored the challenges and needs of children living with parental chronic pain. Young adult children (n=30) of parents with chronic pain were interviewed. Parents (n=20) with chronic pain participated in four focus groups. Content analysis yielded five categories of child challenges: (a) understanding the big picture; (b) enduring hardships; (c) grieving losses; (d) communicating with parent, and; (e) isolating self from peers. Three categories of child needs emerged: (a) knowledge; (b) skills, and; (c) supervised interaction. Understanding these challenges and needs is a vital step in the process of developing evidence-based interventions for this at-risk group.

RESUMEN

Chronic non-cancer pain (CNCP) is a prevalent occurrence and is experienced by adults in their child-rearing years. Communication within the family about parental illness can be formidable, and family members are often uninformed about illness details. To date, there is no research exploring how children and adolescents understand parental chronic pain, a very complex phenomenon, and its related disability. The aim of this study was to develop a substantive theory that describes how adolescents manage the experience of living with a parent suffering with CNCP and environmental factors that help or hinder this process. Grounded theory was used, the focus of which was adolescents' processes of dealing with parental illness in the interpersonal and environmental contexts of their daily lives. A sample of 30 young adults was recruited in northeastern Ohio using theoretical sampling. During open-ended interviews, participants were asked to look back on their adolescence and talk about how they managed living with parental chronic pain. Interview transcripts and field notes were analyzed using constant comparative methods. Six ways of understanding parental chronic pain emerged from the data: noticing something is different, wrestling with not knowing, searching for answers, questioning the validity of pain, developing insight into the complexity of pain, and learning important life lessons. Findings shed light on how adolescents understand and attach meaning and significance to parental chronic pain and disability and serve as the basis for the development of personalized family interventions.

RESUMEN

TOPIC: Chronic noncancer pain (CNCP) is a prevalent occurrence and is experienced by adults in their child-rearing years. Somatic or psychiatric illness in a parent constitutes a potential threat to the physical, mental health, and normative development in children. PURPOSE: A comprehensive review of the literature was performed to answer the question: What are the effects of parental CNCP on children in the family system? SOURCES USED: The search was performed using the Cumulative Index to Nursing and Allied Health Literature, Medline, PsycINFO, and Academic Search Premier. Search terms used were "parent pain or parent chronic pain or parent illness or parent chronic illness" and "child or adolescent or teenager." Inclusion and exclusion criteria were developed a priori. Eighteen articles (n = 18) met criteria and were included in the sample. CONCLUSIONS: Three clusters were identified: (a) child/adolescent somatic complaints or behavior; (b) child/adolescent internalizing or externalizing symptoms; and (c) important mediating and moderating variables. The results of this review show that children and adolescents whose parents suffer from CNCP are at risk for more and similar-to-parent pain complaints and greater degree of internalizing and externalizing symptoms than those with healthy parents. Implications for clinical nursing practice and research are given.

RESUMEN

PURPOSE: The purpose of this article is to describe a substantive theory that details how adolescents manage living with a parent experiencing chronic noncancer pain (CNCP). DESIGN: Grounded theory methods were used to recruit 30 young adults, ages 18 through 21 years, from community settings. METHODS: During open-ended interviews, participants were asked to look back on their adolescence and talk about how they managed living with parental chronic pain. Interview transcripts and field notes were analyzed using constant comparative methods. FINDINGS: Participants who lived with heavily shrouded parents (a) endured hardships; (b) distanced themselves; (c) lamented losses; and (d) held back on revealing their authentic selves. Those who lived with minimally shrouded parents (a) received nurturance and parenting; (b) empathized with their parents' pain situations; (c) lamented losses; and (d) revealed to their parents how parental pain affected them. Participants who connected with significant others "filled the gaps" created by parental pain disability, while those who did not connect with significant others "cooped up" their thoughts, feelings, and needs. CONCLUSIONS: Findings shed light on psychosocial processes and behavior within families experiencing CNCP and serve as the basis for the development of personalized family interventions. CLINICAL RELEVANCE: Nursing interventions should focus on helping adolescents and parents build interpersonal relationship and communication skills. Aggressive diagnosis and treatment of mood disturbance in the parent with CNCP should be part of a holistic treatment plan.

RESUMEN

To help meet the increased requirements for critical nutrients during and around pregnancy, supplementation with essential nutrients is recommended. This study aims to determine how the previous awareness of nutrient health benefits and/or the provision of this information influences the importance placed on nutrients (folate, iodine, omega-3 fatty acids, and vitamin D) when choosing between dietary supplement products for pregnancy. Discrete choice experiment data were collected as part of a cross-sectional online survey administered to 857 pregnant women living in Australia. Four segments of women were identified that differ in their preference criteria when choosing among dietary supplement products for pregnancy. When choosing between products, the reinforcement of perceived health benefits (i.e., showing information on health benefits to those already aware of the benefits) was most effective at increasing the importance of folate (in all segments) and iodine (in two segments, 63% of the sample). Neither prior awareness of health benefits alone nor information provided at the point-of-purchase without prior awareness were enough to increase the importance of folate. Our findings suggest a need for simultaneous strategies that (1) provide information on health benefits before purchase and (2) ensure that information on health benefits is available at the point-of-purchase.

RESUMEN

Using an experimental methodology based on investment games, we examine whether smallholder rice farmers from Nueva Ecija, Philippines have heterogeneous preferences for improvements in 10 rice varietal traits. We use a latent class cluster approach to identify different segments of rice producing households and their distinct preferences for trait improvements. These clusters were characterised post hoc using household, farm, and marketing characteristics. On average, farmers invested the most in rice varietal trait improvements that offered opportunities to reduce losses caused by lodging, insects and diseases. We found four classes of farmers with distinct preferences for improvements in variety traits. The clusters were significantly different in terms of household and farm characteristics. These findings can guide breeding research in the development of varieties that have the traits farmers identified for improvement, and that will address the unique needs of distinct farmer segments.

RESUMEN

The use of a placebo is the gold standard for establishing the efficacy of new treatments in randomized controlled trials (RCTs). Placebo treatments are inert; this allows specific effects of the experimental treatment to be separated from nonspecific physiological, psychological, and social effects. The aim of this study was to scrutinize the workings of an audiobook (AB) placebo treatment, which was used in a placebo-controlled, investigator-blinded, RCT of the effect of guided imagery (GI) to improve pain and function in persons undergoing total knee replacement. A secondary analysis of quantitative and narrative data collected during the RCT was performed. The AB treatment provided attention control. Participants in the AB group identified benefits-pleasant get-away, new knowledge, quiet time-out, and inspiration; however, there was also evidence of resentful demoralization, especially in the postoperative period. The use of ABs as a placebo treatment in GI RCTs should be executed with caution.

RESUMEN

Vietnam is experiencing a diet and nutrition transition. Increasing consumption of food and beverages with added sugars is a significant public health concern. Policies and interventions, such as mandatory nutrition labelling, are being considered to improve consumers' awareness and understanding of diet and health implications of added sugars in food and beverages. The effectiveness of various policy approaches relies on an improved understanding of the interrelationships between urban Vietnamese consumers' health concerns, nutrition label use, and intake of sugars. We empirically disentangle these relationships for urban Vietnamese households using novel intra-household data covering 4047 adults and 737 adolescents from 1590 households in Hanoi and Ho Chi Minh City. The data are from comprehensive household surveys and 24-hour food diaries. Simultaneous equation regression models are estimated using three-stage least squares (3SLS) to account for possible endogeneity. Nutrition label use is significantly associated with a lower share of calories from foods and beverages with added sugars. These findings suggest that nutrition labelling programs may be an effective policy mechanism to reduce the negative health implications of increasing availability and consumption of food and beverages with added sugars in urban Vietnam.
